Question

我正在尝试使用此代码调整UITableView单元格的删除按钮的大小，但出于某种原因，x＆amp;你工作正常，但我无法改变高度和删除按钮的宽度。我在我的自定义UITableViewCell课程中使用此代码，一切正常，优于宽度＆amp; “删除”按钮的高度。我在这里失踪了什么？

- (void)layoutSubviews
{
[super layoutSubviews];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.0f];

for (UIView *subview in self.subviews) {
    if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"]) {

        CGRect newFrame = subview.frame;
        newFrame.origin.x = 250;
        newFrame.origin.y = 47;
        newFrame.size.height = 30;
        newFrame.size.width = 50;

        deleteButtonView.frame = newFrame;
        subview.frame = newFrame;
    }
}
[UIView commitAnimations];}

使用此代码...

if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"]) {
      UIView *deleteButtonView = (UIView *)[subview.subviews objectAtIndex:0];
      CGRect f = deleteButtonView.frame;
      f.origin.x = 250;
      f.origin.y = 47;
      f.size.width = 30;
      f.size.height = 50;

      CGRect sf = self.frame;
      sf.size.width = 100;
      sf.size.height = 100;

      deleteButtonView.frame = f;
      self.frame = sf;
}

在自定义Cell类

中使用此代码

-(void)layoutSubviews
{
  NSMutableArray *subviews = [self.subviews mutableCopy];
  UIView *subV = subviews[0];
  [subviews removeObjectAtIndex:0];
  CGRect f = subV.frame;
  f.size.height = 70; // Here you set height of Delete button
  subV.frame = f;
}

Answer 3

在UITableviewCell中找到“UITableViewCellDeleteConfirmationView”以更改删除按钮的高度。

在自定义单元格类中使用此代码

 - (void)layoutSubviews {
[super layoutSubviews];
NSMutableArray *subviews = [self.subviews mutableCopy];
while (subviews.count > 0)
{
    UIView *subV = subviews[0];
    [subviews removeObjectAtIndex:0];

    if ([NSStringFromClass([subV class])isEqualToString:@"UITableViewCellDeleteConfirmationView"])//Here you select the subView of delete button {
    UIView *deleteButtonView = (UIView *)[self.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 = 70;  //Here you set the height
    deleteButtonView.frame = buttonFrame;

}
}

}

您也可以使用约束（适用于iOS 8.x +）来执行此操作。这样动画（特别是删除按钮动画）保持整洁/没有UI故障。

在你的UITableViewCell子类中：

在您的班级匿名类别中声明弱属性：

gawk

禁用自动调整遮罩约束的转换并添加自己的约束：

awk

覆盖CustomTableViewCell中的func layoutSubviews（）：UITableViewCell

override func layoutSubviews() {

    for subview in self.subviews {

        if String(describing: type(of: subview.self)).isEqualToString("UITableViewCellDeleteConfirmationView") {

            var newFrame = subview.frame
            newFrame.origin.y = 10
            newFrame.size.height = 60
            subview.frame = newFrame
        }
    }
}
