自定义UITableViewRowAction按钮

我想为uitableviewrowaction按钮设置顶部和底部约束

这是我的代码

- (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewRowAction *deleteAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:@"Delete" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){ }]; deleteAction.backgroundColor = [UIColor redColor]; return @[deleteAction]; } 

像这样我添加了删除按钮。 在tableviewCell我添加了一个UIView它有顶部和底部约束。 我希望删除按钮与UITableviewCell视图相UITableviewCell 。

您可以在自定义uitableviewcell类中设置删除按钮框

喜欢这个

  -(void)didTransitionToState:(UITableViewCellStateMask)state { [super didTransitionToState:state]; if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask) { UIView *deleteButton = [self deleteButtonSubview:self]; if (deleteButton) { CGRect frame = deleteButton.frame; frame.origin.y = 4; frame.size.height = frame.size.height-8; /* if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { frame.size.height = 62; //vikram singh 2/1/2015 frame.size.width = 80; } else { frame.size.height = 52; //vikram singh 2/1/2015 frame.size.width = 80; } */ deleteButton.frame = frame; } } } - (UIView *)deleteButtonSubview:(UIView *)view { if ([NSStringFromClass([view class]) rangeOfString:@"Delete"].location != NSNotFound) { return view; } for (UIView *subview in view.subviews) { UIView *deleteButton = [self deleteButtonSubview:subview]; [deleteButton setBackgroundColor:[UIColor whiteColor]]; if (deleteButton) { return deleteButton; } } return nil; } 

使用didTransitionToState方法:)

更多关于Balkaran的回答…删除按钮是一个自定义私有类，但使用String(describing:)方法，你可以合理地确定你可以得到它。
另外，我很惊讶地发现，一旦你开始改变状态， didTransition激活，而不是在状态完成改变时。

Swift 3中@ balkaran代码的更新版本：

 override func didTransition(to state: UITableViewCellStateMask) { super.willTransition(to: state) if state == .showingDeleteConfirmationMask { let deleteButton: UIView? = subviews.first(where: { (aView) -> Bool in return String(describing: aView).contains("Delete") }) if deleteButton != nil { deleteButton?.frame.size.height = 50.0 } 

Answer 4

  super.willTransitionToState(state) if state == .ShowingDeleteConfirmationMask { let deleteButton: UIView? = subviews[0] if deleteButton != nil { var frame: CGRect? = deleteButton?.frame frame?.origin.y = 9 frame?.origin.x = 10 frame?.size.height = (frame?.size.height)! - 14 deleteButton?.frame = frame! } }
