當?UITableView
?的?style
?屬性設置為?Plain
?時,這個tableview的section header在滾動時會默認懸停在界面頂端。取消這一特性的方法有兩種:
- 將?
style
?設置為?Grouped
?。這時所有的section header都會隨著scrollview滾動了。不過?grouped
?和?plain
?的樣式有輕微區別,切換樣式后也許需要重新調整UI - 重載scrollview的delegate方法
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {CGFloat sectionHeaderHeight = 40;if (scrollView.contentOffset.y<=sectionHeaderHeight&&scrollView.contentOffset.y>=0) {scrollView.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, 0, 0, 0);} else if (scrollView.contentOffset.y>=sectionHeaderHeight) {scrollView.contentInset = UIEdgeInsetsMake(-sectionHeaderHeight, 0, 0, 0);}
}
