由 早过忘川 提交于 2020-02-14 05:40:11
问题 After doing some searching and editing, I can't seem to find a solution to fixing this error. I'm trying to link my location search results with a table to display the search results in a list-form. I have my map with the details button linked with a UIViewController called 'FirstViewController.' My results table is linked with a UITableViewController called 'ResultsTableViewController.' My prototype cells are linked with a UITableViewCell called 'ResultsTableCell' which is also where my

iOS 开发 UItableView中滑动删除 cell

主要是就是两个函数 一： - ( void ) tableView: ( UITableView * ) tableView commitEditingStyle: ( UITableViewCellEditingStyle ) editingStyle forRowAtIndexPath: ( NSIndexPath * ) indexPath 相应 editingStyle事件处理 在这里主要相应 UITableViewCellEditingStyleDelete： 二： (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath 在这个函数中设置那个cell设置成 什么样的editingStyle删除，插入，无 UITableViewCellEditingStyleDelete UITableViewCellEditingStyleInsert UITableViewCellEditingStyleNone 需要注意的问题 ：在删除对应cell中的内容时，也要删除这个cell，否则运行时显示效果就像没有刷新 一样，多出一个cell。而使用 [tableView reloadData];[self

Displaying NSMutableAttributedString on iOS 8

由 ＊爱你＆永不变心＊ 提交于 2020-02-13 04:36:43
问题 Seems on iOS 8.0 (12A365) NSMutableAttributedString sometimes will not be displayed correctly. The problem obviously occurs when the range of the attribute does not start at the beginning of the text (and if there is no other attribute starting at the beginning of the text). So with 1.) the second word "green" in will not show the green background (bug!) ("cell" is a UITableViewCell with UILabel "label" as a subview): 1.) text = [[NSMutableAttributedString alloc] initWithString:@"Green is

在做tableView的时候，我们有时候须要依据cell的高度动态来调整。近期在网上看到一段代码不错。跟大家Share一下。 在 -( UITableViewCell *)tableView:( UITableView *)tableView cellForRowAtIndexPath:( NSIndexPath *)indexPath{ 类中获取cell的高度： CGSize boundSize = CGSizeMake(216, CGFLOAT_MAX); cell.textLabel.text = @"12345678900123456789"; cell.userInteractionEnabled = NO; cell.textLabel.numberOfLines = 0; CGSize requiredSize = [cell.textLabel.text sizeWithFont:[UIFont systemFontOfSize:13] constrainedToSize:boundSize lineBreakMode:UILineBreakModeWordWrap]; CGRect rect = cell.frame; rect.size.height = requiredSize.height+5; cell.frame = rect;

由 江枫思渺然 提交于 2020-02-11 07:14:25
问题 I'm trying to get the height of all of a table's contents so I can update the container it is in. This will allow the container and other views in the scroll view to scroll together. 回答1: Swift : var tableViewHeight: CGFloat { tableView.layoutIfNeeded() return tableView.contentSize.height } Objective-C - (CGFloat)tableViewHeight { [tableView layoutIfNeeded]; return [tableView contentSize].height; } 回答2: Swift 3 override func viewDidLoad() { super.viewDidLoad() myTbleView.addObserver(self,
