设置UITableViewCell中滑动时显示的删除按钮的高度

Question

我有UITableViewCell，如下图所示。

单元格占据删除占用的高度。设置单元高度以便保持两个单元之间的间隔。

现在，当我滑动并删除按钮时出现（红色），它占据了上图中给出的单元格高度。我只想将其高度设置为仅白色部分的高度或者说出灰色按钮的高度。任何人都可以帮我了解如何设置在UITableViewCell中滑动后显示的删除按钮的高度？

Answer 1

解决这个问题的最佳方法是重写

-(void)layoutSubviews in YourCustomCell:UITableViewCell    

然后

if ([NSStringFromClass([subview class])isEqualToString:@"UITableViewCellDeleteConfirmationControl"]){
            UIView *deleteButtonView = (UIView *)[subview.subviews objectAtIndex:0];
                                CGRect buttonFrame = deleteButtonView.frame;
                                buttonFrame.origin.x = Xvalue;
                                buttonFrame.origin.y = Yvalue;
                                buttonFrame.size.width = Width;
                                buttonFrame.size.height = Height;
                                deleteButtonView.frame = buttonFrame;

         }

在自定义Cell类

中使用此代码

 -(void) layoutSubviews
{
    NSMutableArray *subviews = [self.subviews mutableCopy];
    UIView *subV = subviews[0];
    if ([NSStringFromClass([subV class])isEqualToString:@"UITableViewCellDeleteConfirmationView"]){
      [subviews removeObjectAtIndex:0];
      CGRect f = subV.frame;
      f.size.height = 106; // Here you set height of Delete button
      subV.frame = f;
     }

}

将此方法添加到customCell.m文件中。

-(void) layoutSubviews
{
    NSMutableArray *subviews = [self.subviews mutableCopy];
    UIView *subview = subviews[0];

    if ([NSStringFromClass([subview class])isEqualToString:@"UITableViewCellDeleteConfirmationView"]){
        UIView *deleteButtonView = (UIView *)[subview.subviews objectAtIndex:0];
        CGRect buttonFrame = deleteButtonView.frame;
        buttonFrame.origin.x = deleteButtonView.frame.origin.x;
        buttonFrame.origin.y = deleteButtonView.frame.origin.y;
        buttonFrame.size.width = deleteButtonView.frame.size.width;
        buttonFrame.size.height = 46;
        deleteButtonView.frame = buttonFrame;
        subview.frame=CGRectMake(subview.frame.origin.x, subview.frame.origin.y, subview.frame.size.width, 46);
        deleteButtonView.clipsToBounds=YES;
        subview.clipsToBounds=YES;
    }
}

Swift 5，适用于 iOS12、iOS13 和 iOS14

  func tableView(_ tableView: UITableView, willBeginEditingRowAt indexPath: IndexPath) {
    // for iOS13, iOS14
    if let swipeContainerView = tableView.subviews.first(where: { String(describing: type(of: $0)) == "_UITableViewCellSwipeContainerView" }) {
      if let swipeActionPullView = swipeContainerView.subviews.first, String(describing: type(of: swipeActionPullView)) == "UISwipeActionPullView" {
        swipeActionPullView.frame.size.height -= 10
      }
    }

    // for iOS12
    tableView.subviews.forEach { subview in
      if String(describing: type(of: subview)) == "UISwipeActionPullView" {
        subview.frame.size.height -= 10
      }
    }
  }

Answer 5

对于IOS 13，位置已再次更改，而不是在表视图内更改，它再次在_UITableViewCellSwipeContainerView中。因此，您也应该对其进行迭代。请在下面查看

([NSStringFromClass([subview class]) 
 isEqualToString:@"_UITableViewCellSwipeContainerView"]){

        for (UIView *deleteButtonSubview in subview.subviews){

            if ([NSStringFromClass([deleteButtonSubview class])
                 isEqualToString:@"UISwipeActionPullView"]) {



                if ([NSStringFromClass([deleteButtonSubview.subviews[0] class]) isEqualToString:@"UISwipeActionStandardButton"]) {

                   //do what you want
                }
            }

        }
    }

Answer 6

要了解它在IOS 11中的工作原理，请将此Swift 4代码段复制到UITableViewController中：

/var/lib/mysql/

此代码适用于IOS 11及更高版本

在自定义单元格中写下以下代码，希望它对您有用 -

- (void)willTransitionToState:(UITableViewCellStateMask)state
{
    [super willTransitionToState:state];
    if(state == UITableViewCellStateShowingDeleteConfirmationMask)
     {
        [self performSelector:@selector(resetDeleteButtonSize) withObject:nil afterDelay:0];
     }
 }



- (void)resetDeleteButtonSize
{
    NSMutableArray *subviews = [self.subviews mutableCopy];
    while (subviews.count > 0)
    {
        UIView *subV = subviews[0];
        [subviews removeObjectAtIndex:0];
        if ([NSStringFromClass([subV class])isEqualToString:@"UITableViewCellDeleteConfirmationButton"])
        {
            CGRect f = subV.frame;
            f.size.height = 74;
            subV.frame = f;
            break;
        }
        else
        {
            [subviews addObjectsFromArray:subV.subviews];
        }
    }
}
