登陸注冊及推出主頁面

這部分有兩種寫法：一種是在SceneDelegate中推出LoginVC，后在判斷登陸成功后退去主要程序。另一種則是先加載主程序，后推出登陸頁面。通過同組同學實踐證明，后者在推出登陸頁面時會閃一下，因此還是建議采用第一種方法。

本人的登陸頁面在最初使用數組儲存用戶名和密碼，后來發現在修改密碼時會較為困難，因此我創建了一個單例類。

同時我簡單了解了一種輕量化本地存儲方式?setObject: forKey:?

他支持的對象類型包括：

類型	示例
NSString	用戶名、token 等
NSNumber	整數、布爾值等
NSArray	字符串數組、數字數組等
NSDictionary	鍵值對結構
NSDate	時間
NSData	二進制數據（如圖片、加密）

- (void)saveLoginStatus {NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];[defaults setObject:@"wutong" forKey:@"username"];[defaults setBool:YES forKey:@"isLoggedIn"];[defaults synchronize]; // 可選
}//讀取時NSString *name = [[NSUserDefaults standardUserDefaults] objectForKey:@"username"];
BOOL isLoggedIn = [[NSUserDefaults standardUserDefaults] boolForKey:@"isLoggedIn"];

NSUserDefaults?的?setObject:forKey:?是用于保存簡單用戶數據的 API，輕量、易用，適合設置類數據（如用戶名、偏好設置、登錄狀態等）。?

//  UserManager.m
//  3GShareee
//
//  Created by 吳桐 on 2025/7/18.
//#import "UserManager.h"@implementation UserManager//單例
+ (instancetype)sharedManager {static UserManager *manager = nil;static dispatch_once_t onceToken;dispatch_once(&onceToken, ^{manager = [[UserManager alloc] init];[manager loadUserData];});return manager;
}- (id)init {self = [super init];if (self) {_usernames = [NSMutableArray array];_passwords = [NSMutableArray array];[_usernames addObject:@"1"];[_passwords addObject:@"1"];}return self;
}//保存到本地
- (void)saveUserData {[[NSUserDefaults standardUserDefaults] setObject:self.usernames forKey:@"savedUsernames"];[[NSUserDefaults standardUserDefaults] setObject:self.passwords forKey:@"savedPasswords"];[[NSUserDefaults standardUserDefaults] synchronize];    //不懂，好像是保存
}- (void)loadUserData {NSArray *savedUsernames = [[NSUserDefaults standardUserDefaults] objectForKey:@"savedUsernames"];NSArray *savedPasswords = [[NSUserDefaults standardUserDefaults] objectForKey:@"savedPasswords"];NSDictionary *savedGenders = [[NSUserDefaults standardUserDefaults] objectForKey:@"savedUserGenders"];if (savedUsernames) {self.usernames = [savedUsernames mutableCopy];}if (savedPasswords) {self.passwords = [savedPasswords mutableCopy];}if (![self.usernames containsObject:@"1"]) {[self.usernames addObject:@"1"];[self.passwords addObject:@"1"];}
}- (BOOL)updatePasswordForUser:(NSString *)username oldPassword:(NSString *)oldPassword newPassword:(NSString *)newPassword {NSUInteger index = [self.usernames indexOfObject:username];if (index == NSNotFound) {  //NSNotFound 是 Objective-C 中的一個常量，表示“沒有找到”的情況，常用于查找操作的結果。return NO;}if (![oldPassword isEqualToString:self.passwords[index]]) {return NO;}// 更新密碼self.passwords[index] = newPassword;[self saveUserData];return YES;
}@end

同時，我設置了管理員密碼1 1，用于繞過調試時便捷登陸，不必輸入較長密碼。注冊功能和修改密碼功能中，密碼為不小于6位的數字或字母。

自動登錄

我設置了autoBtn，和autoBtn01。前者為切換的按鈕主體，后者為一個輔助按鈕，當用戶點擊文字時，也會觸發和前者相同的函數從而實現按鈕圖標的切換，更加人性化。

[self.autoBtn setImage: [UIImage imageNamed: @"autoreserved.png"] forState: UIControlStateNormal];[self.autoBtn setImage: [UIImage imageNamed: @"autohighlighted.png"] forState: UIControlStateSelected];self.autoBtn.selected = NO;[self.autoBtn addTarget: self action: @selector(pressAuto) forControlEvents: UIControlEventTouchUpInside];self.autoBtn1 = [UIButton buttonWithType: UIButtonTypeRoundedRect];self.autoBtn1.frame = CGRectMake(67, 550, 64, 16);[self.autoBtn1 setTitle: @"自動登錄" forState: UIControlStateNormal];[self.autoBtn1 setTintColor: [UIColor colorWithDisplayP3Red: 14.0 / 255 green: 46.0 / 255 blue: 121.0 / 255 alpha: 1.0]];[self.autoBtn1 addTarget: self action: @selector(pressAuto) forControlEvents: UIControlEventTouchUpInside];

自動收起鍵盤

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {[self.view endEditing:YES];
}

這兩個方法筆者暫時也不算很清楚講述，只算一知半解，只知道能實現這個功能?

- (void)keyboardWillAppear:(NSNotification *)notification{CGRect keyboardFrame = [notification.userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];CGFloat keyboardY = keyboardFrame.origin.y;[UIView animateWithDuration:0.3 animations:^{self.view.transform = CGAffineTransformMakeTranslation(0, keyboardY - self.view.frame.size.height + 20);}];
}- (void)keyboardWillDisAppear:(NSNotification *)notification{[UIView animateWithDuration:0.3 animations:^{self.view.transform = CGAffineTransformIdentity;}];
}

注冊

核心代碼如下

-(void) pressConfirm {NSString *username = self.usernameTextField.text;NSString *password = self.passwordTextField.text;UserManager *userManager = [UserManager sharedManager];if (username.length == 0 || password.length == 0) {UIAlertController* warning = [UIAlertController alertControllerWithTitle:@"提示"message:@"賬號或密碼不能為空"preferredStyle:UIAlertControllerStyleAlert];UIAlertAction* warn = [UIAlertAction actionWithTitle:@"確定"style:UIAlertActionStyleDefaulthandler:nil];[warning addAction:warn];[self presentViewController:warning animated:YES completion:nil];return;}// 檢查密碼長度是否大于6位if (password.length < 6) {UIAlertController* warning = [UIAlertController alertControllerWithTitle:@"提示"message:@"密碼長度必須大于6位"preferredStyle:UIAlertControllerStyleAlert];UIAlertAction* warn = [UIAlertAction actionWithTitle:@"確定"style:UIAlertActionStyleDefaulthandler:nil];[warning addAction:warn];[self presentViewController:warning animated:YES completion:nil];return;}// 檢查用戶名是否已存在if ([userManager.usernames containsObject:username]) {UIAlertController* warning = [UIAlertController alertControllerWithTitle:@"提示"message:@"該用戶名已被注冊"preferredStyle:UIAlertControllerStyleAlert];UIAlertAction* warn = [UIAlertAction actionWithTitle:@"確定"style:UIAlertActionStyleDefaulthandler:nil];[warning addAction:warn];[self presentViewController:warning animated:YES completion:nil];return;}// 所有檢查通過，注冊新用戶[userManager.usernames addObject:username];[userManager.passwords addObject:password];[userManager saveUserData]; // 保存到磁盤// 顯示注冊成功提示UIAlertController* successAlert = [UIAlertController alertControllerWithTitle:@"注冊成功"message:@"您已成功注冊"preferredStyle:UIAlertControllerStyleAlert];UIAlertAction* okAction = [UIAlertAction actionWithTitle:@"確定"style:UIAlertActionStyleDefaulthandler:^(UIAlertAction * _Nonnull action) {// 關閉注冊頁面[self dismissViewControllerAnimated:YES completion:nil];}];[successAlert addAction:okAction];[self presentViewController:successAlert animated:YES completion:nil];// 清空輸入框self.usernameTextField.text = @"";self.passwordTextField.text = @"";self.emailTextField.text = @"";
}

FirstVC

因為文章的格式類似如圖，我新建了一個cell用于設置所有類似的頁面，textTableViewCell

首頁中，我們需要在點擊假日時跳轉到另一個頁面，同時實現兩個頁面之間的點贊同步。

---

先來說說推出假日頁面。

我在texttableView中添加了一個手勢識別

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc]initWithTarget:selfaction:@selector(CellTap)];[self.contentView addGestureRecognizer:tapGesture];

// 告訴我被點擊了
- (void)CellTap {if ([self.delegate respondsToSelector:@selector(textTableViewCellDidTap:)]) {[self.delegate textTableViewCellDidTap:self];}
}

在首頁中： 我們只處理第一行的情況

- (void)textTableViewCellDidTap:(textTableViewCell *)cell {NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];if (indexPath.section == 1 && indexPath.row == 0) {NSMutableDictionary *holidayData = [self.dataArray[0] mutableCopy];HolidayDetailViewController *detailVC = [[HolidayDetailViewController alloc] init];detailVC.holidayData = holidayData;detailVC.delegate = self;detailVC.isLiked = [holidayData[@"isLiked"] boolValue]; // 傳遞當前點贊狀態// 推入導航棧[self.navigationController pushViewController:detailVC animated:YES];}
}

---

再來說說點贊。

其實下圖中的方法更為簡便，不需要我的多重傳值

列表頁點贊：
textTableViewCell (按鈕點擊) → FirstVC (更新數據源) → 刷新UI

詳情頁點贊：
HolidayDetailViewController → FirstVC (通過代理回調) → 更新數據源 → 刷新列表頁單元格

傳值法：

列表頁點贊：

在textCell中：

- (void)likeButtonTapped:(UIButton *)sender {sender.selected = !sender.selected;//一種保護 檢查是否實現方法if ([self.delegate respondsToSelector:@selector(textTableViewCell:didChangeLikeStatus:)]) {[self.delegate textTableViewCell:self didChangeLikeStatus:sender.selected];//調用代理方法}
}

對應FirstVC中：

- (void)textTableViewCell:(textTableViewCell *)cell didChangeLikeStatus:(BOOL)isLiked {NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];if (indexPath.row < self.dataArray.count) {NSMutableDictionary *item = [self.dataArray[indexPath.row] mutableCopy];item[@"isLiked"] = @(isLiked);self.dataArray[indexPath.row] = item;}
}

詳情頁點贊：

holidayVC:?

- (void)pressLike {self.isLiked = !self.isLiked;self.likeIcon.selected = self.isLiked;//通過代理通知列表頁if ([self.delegate respondsToSelector:@selector(holidayDetail:didChangeLikeStatus:)]) {[self.delegate holidayDetail:self didChangeLikeStatus:self.isLiked];}
}

FirstVC:

- (void)holidayDetail:(HolidayDetailViewController *)detail didChangeLikeStatus:(BOOL)isLiked {NSMutableDictionary *holidayData = [self.dataArray[0] mutableCopy];holidayData[@"isLiked"] = @(isLiked);self.dataArray[0] = holidayData;NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:1];//這個函數可以刷新單元格[self.tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}

SecondVC

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {if ([self.searchBar.text isEqualToString:@"大白"]) {SearchResultViewController* searchResultsView = [[SearchResultViewController alloc] init];[self.navigationController pushViewController: searchResultsView animated: YES];}
}

還有一部分是上傳頁面?

實現效果如圖。兩個textField用來輸入作品名稱和文章內容

折疊cell：

   self.foldButton = [UIButton buttonWithType:UIButtonTypeCustom];self.foldButton.frame = CGRectMake(315, 168, 48, 48);UIImage *foldImage = [UIImage imageNamed:@"guanbi.png"];[self.foldButton setImage:foldImage forState:UIControlStateNormal];[self.foldButton setTintColor:[UIColor colorWithRed:0.2 green:0.6 blue:0.9 alpha:1.0]];[self.foldButton addTarget:self action:@selector(pressUnfold) forControlEvents:UIControlEventTouchUpInside];[self.view addSubview:self.foldButton];

- (void)pressUnfold {[UIView animateWithDuration:0.3 animations:^{if (self.isFolded) {self.foldTableView.frame = CGRectMake(225, 180, 110, self.foldCellArray.count * 25);[self.foldButton setImage:[UIImage imageNamed:@"kaiqi.png"] forState:UIControlStateNormal];} else {self.foldTableView.frame = CGRectMake(225, 180, 110, 25);[self.foldButton setImage:[UIImage imageNamed:@"guanbi.png"] forState:UIControlStateNormal];}}];self.isFolded = !self.isFolded;[self.foldTableView reloadData]; // 刷新表格以顯示正確行數
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {if (!self.isFolded) {NSString *selectedCategory = self.foldCellArray[indexPath.row];if (indexPath.row != 0) {[self.foldCellArray removeObjectAtIndex:indexPath.row];[self.foldCellArray insertObject:selectedCategory atIndex:0];}[self pressUnfold];} else {[self pressUnfold];}
}

上傳圖片：?

一個choosePhoto按鈕用來彈出照片墻，另一個numbersOfPhotolabel用來顯示選中的照片數量。如上文示范圖。

- (void)pressChoosePhotoButton {PhotoWallViewController* photoWallViewController = [[PhotoWallViewController alloc] init];photoWallViewController.delegate = self;[self.navigationController pushViewController: photoWallViewController animated: YES];
}

- (void)pressPhoto: (UIButton*)button {if (button.selected == NO) {int selectNumber = (int)(button.tag - 100);self.numbersOfPhoto++;[self.imageNameArray addObject: [NSString stringWithFormat: @"photo%d.jpg", selectNumber]];button.selected = YES;} else {int selectNumber = (int)(button.tag - 100);self.numbersOfPhoto--;[self.imageNameArray removeObject: [NSString stringWithFormat: @"photo%d.jpg", selectNumber]];button.selected = NO;}
}

NSString* message = [NSString stringWithFormat: @"成功上傳 %d 張圖片!", self.numbersOfPhoto];UIAlertController* boomAlert = [UIAlertController alertControllerWithTitle: @"提示" message: message preferredStyle: UIAlertControllerStyleAlert];UIAlertAction* boomAction= [UIAlertAction actionWithTitle: @"確定" style: UIAlertActionStyleDefault handler: ^(UIAlertAction *action) {// 返回前調用代理方法if ([self.delegate respondsToSelector:@selector(changedPhotoName:andNumber:)]) {[self.delegate changedPhotoName:self.imageNameArray.firstObject andNumber:self.numbersOfPhoto];}[self.navigationController popViewControllerAnimated: YES];}];[boomAlert addAction: boomAction];[self presentViewController: boomAlert animated:YES completion:nil];

注意，在這里我們傳回來的是數組的第一個元素

- (void)changedPhotoName:(NSString *)nameOfPhoto andNumber:(int)numbersOfPhoto {self.numbersOfPhoto = numbersOfPhoto;if (nameOfPhoto) {[self.choosePhoto setBackgroundImage:[UIImage imageNamed:nameOfPhoto] forState:UIControlStateNormal];[self.choosePhoto setTitle:@"" forState:UIControlStateNormal];}// 更新圖片數量標簽self.numbersOfPhotoLabel.text = [NSString stringWithFormat:@"%d", numbersOfPhoto];self.numbersOfPhotoLabel.hidden = (numbersOfPhoto == 0);
}

?在發布頁面修改照片數量，同時修改那個背景。

ThirdVC

直接注冊三個一模一樣的cell，以實現互不干涉。古老簡單但是有效

- (void)setupTableViews {CGFloat tableHeight = HEIGHT - 150;self.tableView01 = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, WIDTH, tableHeight) style:UITableViewStylePlain];self.tableView01.delegate = self;self.tableView01.dataSource = self;self.tableView01.backgroundColor = [UIColor whiteColor];self.tableView01.showsVerticalScrollIndicator = NO;self.tableView01.separatorStyle = UITableViewCellSeparatorStyleNone;self.tableView02 = [[UITableView alloc] initWithFrame:CGRectMake(WIDTH, 0, WIDTH, tableHeight) style:UITableViewStylePlain];self.tableView02.delegate = self;self.tableView02.dataSource = self;self.tableView02.backgroundColor = [UIColor whiteColor];self.tableView02.showsVerticalScrollIndicator = NO;self.tableView02.separatorStyle = UITableViewCellSeparatorStyleNone;self.tableView03 = [[UITableView alloc] initWithFrame:CGRectMake(WIDTH * 2, 0, WIDTH, tableHeight) style:UITableViewStylePlain];self.tableView03.delegate = self;self.tableView03.dataSource = self;self.tableView03.backgroundColor = [UIColor whiteColor];self.tableView03.showsVerticalScrollIndicator = NO;self.tableView03.separatorStyle = UITableViewCellSeparatorStyleNone;// 注冊cell[self.tableView01 registerClass:[textTableViewCell class] forCellReuseIdentifier:@"cell"];[self.tableView02 registerClass:[textTableViewCell class] forCellReuseIdentifier:@"cell"];[self.tableView03 registerClass:[textTableViewCell class] forCellReuseIdentifier:@"cell"];[self.scrollView addSubview:self.tableView01];[self.scrollView addSubview:self.tableView02];[self.scrollView addSubview:self.tableView03];
}- (void)createArticles {UIImage *defaultImage = [UIImage systemImageNamed:@"photo"];self.articlesSection0 = [NSMutableArray arrayWithArray:@[@{@"thumbnail": [UIImage imageNamed:@"article1"] ?: defaultImage, @"title": @"如期而至", @"author": @"SHARE 鋼蛋", @"category": @"", @"time": @"16", @"isLiked": @NO},@{@"thumbnail": [UIImage imageNamed:@"article2"] ?: defaultImage, @"title": @"duck的學問", @"author": @"SHARE 王二麻", @"category": @"", @"time": @"20", @"isLiked": @NO},@{@"thumbnail": [UIImage imageNamed:@"article3"] ?: defaultImage, @"title": @"您的故事", @"author": @"SHARE 和尚", @"category": @"", @"time": @"25", @"isLiked": @NO},@{@"thumbnail": [UIImage imageNamed:@"article4"] ?: defaultImage, @"title": @"八月的故事", @"author": @"SHARE 二五", @"category": @"", @"time": @"60", @"isLiked": @NO},@{@"thumbnail": [UIImage imageNamed:@"article5"] ?: defaultImage, @"title": @"我們終將再見", @"author": @"SHARE 小唐", @"category": @"", @"time": @"60", @"isLiked": @NO}]];self.articlesSection1 = [self.articlesSection0 mutableCopy];self.articlesSection2 = [self.articlesSection0 mutableCopy];
}

FourthVC

FifthVC

我上傳的

直接調用ThirdVC中的頁面

我的信息

評論 && 活動通知 && 我的推薦

這段代碼我也沒有很懂，只知道能實現一個類似這樣的效果

UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil message:@"沒有新內容" preferredStyle:UIAlertControllerStyleAlert];[self presentViewController:alert animated:YES completion:nil];dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{[alert dismissViewControllerAnimated:YES completion:nil];});

新關注的

這部分需要實現一個關注的留存如下圖

?通過如下方式可以確保只創建一個followVC，進而保存之前的關注。

@property (nonatomic, strong) followViewController *followVC;else if ([messageType isEqualToString:@"新關注的"]) {// 使用強引用確保只創建一次 followViewControllerif (!_followVC) {_followVC = [[followViewController alloc] init];_followVC.title = @"關注列表";_followVC.view.backgroundColor = [UIColor whiteColor];}[self.navigationController pushViewController:_followVC animated:YES];

私信：

首先要隱藏tabBar

// 隱藏tabBar
- (void)viewWillAppear:(BOOL)animated {[super viewWillAppear:animated];self.tabBarController.tabBar.hidden = YES;
}// 恢復tabBar
- (void)viewWillDisappear:(BOOL)animated {[super viewWillDisappear:animated];self.tabBarController.tabBar.hidden = NO;
}

- (void)setupMessages {_messageArray = [NSMutableArray array];_rowHeightArray = [NSMutableArray array];[self addMessage:@"1～365選一個數字" isOutgoing:NO];[self addMessage:@"52" isOutgoing:YES];[self addMessage:@"我會在接下來的365天一直愛你" isOutgoing:NO];[self addMessage:@"我能不能重新選" isOutgoing:YES];[self addMessage:@"能" isOutgoing:NO];[self addMessage:@"1" isOutgoing:YES];[self addMessage:@"你只需要愛我一天，剩下的364天我來愛你" isOutgoing:YES];[self scrollToBottom];
}- (void)addMessage:(NSString *)message isOutgoing:(BOOL)isOutgoing {//添加NSDictionary *messageDict = @{@"text": message,@"outgoing": @(isOutgoing)};[_messageArray addObject:messageDict];NSDictionary *attri = @{NSFontAttributeName: [UIFont systemFontOfSize:16]};  //16號字體//boundingRectWithSize:... 是 NSString 的一個方法：“請你告訴我最大容納的尺寸，我會幫你計算出這段字符串在這些限制下需要多大的空間。”CGSize size = [message boundingRectWithSize:CGSizeMake(WIDTH * 0.6, CGFLOAT_MAX)options:NSStringDrawingUsesLineFragmentOrigin //繪圖時請考慮換行，按段落來布局文字attributes:attri    //就是第1行設置的字體屬性字典。告訴系統你用什么樣的字體來繪制這段文字。context:nil].size;  //一般用于繪圖時提供額外信息，但我們這里只是“量尺寸”，所以設置為 nil。CGFloat height = MAX(60, size.height + 40);//行高[_rowHeightArray addObject:@(height)];
}- (void)sendMessage {if (self.textField.text.length == 0) return;[self addMessage:self.textField.text isOutgoing:self.isNextOutgoing];self.isNextOutgoing = !self.isNextOutgoing; //實現交替發送NSIndexPath *indexPath = [NSIndexPath indexPathForRow:self.messageArray.count - 1 inSection:0];[self.tableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationBottom];//滑到底部[self scrollToBottom];self.textField.text = @"";
}- (void)scrollToBottom {if (self.messageArray.count > 0) {NSIndexPath *indexPath = [NSIndexPath indexPathForRow:self.messageArray.count - 1 inSection:0];[self.tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];}
}- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {//cell復用static NSString *cellIdentifier = @"MessageCell";UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];if (!cell) {cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];cell.selectionStyle = UITableViewCellSelectionStyleNone;cell.backgroundColor = [UIColor clearColor];} else {//清除原先的子視圖for (UIView *subview in cell.contentView.subviews) {[subview removeFromSuperview];}}

設置

基本資料需要保存之前修改后的男女性別 不能人家改成女的推出去以后又成男的了

還是以前那個方法，只創建一次

- (void)showBasicInfo {if (!_basicsVC) {_basicsVC = [[basicsViewController alloc] init];_basicsVC.view.backgroundColor = [UIColor whiteColor];}[self.navigationController pushViewController:_basicsVC animated:YES];
}

修改密碼：

- (void)pressButton {NSString *oldPassword = self.firstTextField.text;NSString *newPassword = self.secondTextField.text;NSString *confirmPassword = self.thirdTextField.text;UserManager *userManager = [UserManager sharedManager];NSString *currentUser = userManager.currentUser;if (currentUser.length == 0) {// 沒有當前登錄用戶self.alertController = [UIAlertController alertControllerWithTitle:@"錯誤"message:@"無法獲取當前登錄用戶信息"preferredStyle:UIAlertControllerStyleAlert];}// 檢查新密碼長度else if (newPassword.length < 6 || newPassword.length > 20) {self.alertController = [UIAlertController alertControllerWithTitle:@"通知"message:@"密碼需為6-20位英文或數字組合"preferredStyle:UIAlertControllerStyleAlert];}// 檢查兩次密碼是否一致else if (![newPassword isEqualToString:confirmPassword]) {self.alertController = [UIAlertController alertControllerWithTitle:@"通知"message:@"兩次新密碼輸入不同"preferredStyle:UIAlertControllerStyleAlert];}// 檢查新密碼是否與舊密碼相同else if ([oldPassword isEqualToString:newPassword]) {self.alertController = [UIAlertController alertControllerWithTitle:@"通知"message:@"新密碼不能與舊密碼相同"preferredStyle:UIAlertControllerStyleAlert];}// 嘗試修改密碼else {// 調用用戶管理類修改密碼if ([userManager updatePasswordForUser:currentUser oldPassword:oldPassword newPassword:newPassword]) {self.alertController = [UIAlertController alertControllerWithTitle:@"成功"message:@"密碼修改成功"preferredStyle:UIAlertControllerStyleAlert];// 修改成功后清空密碼框self.firstTextField.text = @"";self.secondTextField.text = @"";self.thirdTextField.text = @"";} else {self.alertController = [UIAlertController alertControllerWithTitle:@"錯誤"message:@"舊密碼不正確"preferredStyle:UIAlertControllerStyleAlert];}}UIAlertAction *sure = [UIAlertAction actionWithTitle:@"確定" style:UIAlertActionStyleDefault handler:nil];[self.alertController addAction:sure];[self presentViewController:self.alertController animated:YES completion:nil];
}

對應UserManger中：

- (BOOL)updatePasswordForUser:(NSString *)username oldPassword:(NSString *)oldPassword newPassword:(NSString *)newPassword {NSUInteger index = [self.usernames indexOfObject:username];if (index == NSNotFound) {  //NSNotFound 是 Objective-C 中的一個常量，表示“沒有找到”的情況，常用于查找操作的結果。return NO;}if (![oldPassword isEqualToString:self.passwords[index]]) {return NO;}// 更新密碼self.passwords[index] = newPassword;[self saveUserData];return YES;
}

其他頁面：在此不過多贅述了

Tips：

self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone; // 移除分隔線

這個代碼可以用來移除cell間的分界線

 UIBarButtonItem* btn = [[UIBarButtonItem alloc] initWithImage: [UIImage imageNamed: @"holidayfanhui.png"] style: UIBarButtonItemStylePlain target: self action: @selector(pressReturn)];self.navigationItem.leftBarButtonItem = btn;btn.tintColor = [UIColor whiteColor];- (void)pressReturn {[self.navigationController popViewControllerAnimated: YES];
}

這段代碼可以用來自定義返回鍵類

// 在tabBar上方添加自定義覆蓋視圖UIView* overlayView = [[UIView alloc] initWithFrame:CGRectMake(0, 50, WIDTH, tabBarViewController.tabBar.bounds.size.height)];overlayView.backgroundColor = [UIColor blackColor];[tabBarViewController.tabBar addSubview:overlayView];

這個代碼可以實現遮擋tabBar和屏幕底部之間的區域，更加美觀，當然如果為了更加自然可以自己調顏色。?
