Question

我正在尝试使用以下代码在UITableViewCell中以宽度方式居中UIImageView：

        // self.cover_image is a UIImage variable
        // cell is a UITableCellView

        UIImageView* backcover_imageview = [[[UIImageView alloc] initWithImage:self.cover_image] autorelease];
        [backcover_imageview sizeToFit];

        //center image
        //float xPos = cell.contentView.frame.size.width - (self.cover_image.size.width/2);

        //TODO: need better solution
        //Eyeballing attempt:
        float xPos = self.cover_image.size.width - 25;
        CGRect bookcover_frame = backcover_imageview.frame;
        bookcover_frame.origin.x = xPos;
        backcover_imageview.frame = bookcover_frame;
        backcover_imageview.tag = 9000;
        backcover_imageview.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;

        [cell.contentView addSubview:backcover_imageview];

无论iPad或iPhone设备的方向如何，我都试图将UIImageView置于UITableCellView中心。有没有人知道正确的方法呢？

Answer 1

我添加了两个自动修复蒙版，并使用您的代码和PengOne的答案获得了良好的结果：

playImage.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
[cell.contentView addSubview:playImage];
playImage.center = CGPointMake(cell.contentView.bounds.size.width/2,cell.contentView.bounds.size.height/2);

Answer 2

将backcover_imageView添加到单元格的contentView后，使用此选项将其居中：

imageView.center = CGPointMake(cell.contentView.bounds.size.width/2,cell.contentView.bounds.size.height/2);

Answer 3

您可以尝试将单元格的center属性指定为图像视图的中心属性吗？

像这样的东西

imageView.center = cell.center;

然后将其添加到单元格中。

Answer 4

您可以使用单元格的中心锚点将图像保持在中心：

image.centerXAnchor.constraint(equalTo: cell.centerXAnchor).isActive = true
image.centerYAnchor.constraint(equalTo: cell.centerYAnchor).isActive = true

无论方向如何，如何将UIImageView置于UITableViewCell中心？
