Question

这是一种正确的方法还是有更好的解决方案？

非常感谢！

Code（rowAtIndexPath）

UIImageView * imageView = [[UIImageView alloc] initWithFrame:CGRectMake(500, 50, 20, 20)];
        imageView.image = [UIImage imageNamed:@"Icon.png"];
        [cell addSubview:imageView];

Answer 1

您应该将视图添加到单元格的contentView而不是单元格的视图中。这是一个例子：

UIImageView * imageView = [[UIImageView alloc] initWithFrame:CGRectMake(500, 50, 20, 20)];
imageView.image = [UIImage imageNamed:@"Icon.png"];
[cell.contentView addSubview:imageView];

Answer 2

UIImageView * imageView = [[UIImageView alloc] initWithFrame:CGRectMake(cell.contentView.frame.origin.x, cell.contentView.frame.size.height, 20, 20)];

imageView.image = [UIImage imageNamed:@"Icon.png"];
[cell.contentView addSubview:imageView];

这是正确的。对于UITableView的大型列表。如果您使用[cell addSubview:]，对于大型列表，它看起来就像闪烁一样。

Answer 3

有我的代码，它运作良好。希望它可以帮助你。

UIImageView * imageView = [[UIImageView alloc] initWithFrame:CGRectMake(cell.contentView.frame.origin.x, cell.contentView.frame.size.height, 20, 20)];
imageView.image = [UIImage imageNamed:@"Icon.png"];
[cell.contentView addSubview:imageView];

Answer 4

对于Swift 3

let imgView : UIImageView = UIImageView(frame: CGRect(x: 500, y: 50, width: 70, height: 70)) 
     //CALayer for rounded image 
        let imageCALayer : CALayer = imgView.layer
        imageCALayer.cornerRadius = 35
        imageCALayer.masksToBounds = true
        imgView.image = UIImage(string: "Icon.png")
        cell.contentView.addSubview(imgView)

将UIImageView添加到自定义UITableView Cell
