删除UITableViewCell上的填充 [英] Remove padding on UITableViewCell

问题描述

在 UITableViewCell 与 UITableViewCellStyleSubtitle 样式，我设置 imageView.image ， textLabel.text 和 detailTextLabel.text 。单元格周围有白色填充。如何摆脱填充，所有我的图像互相接触，像下面的Youtube应用程序？

On a UITableViewCell with UITableViewCellStyleSubtitle styling, I'm setting the imageView.image, textLabel.text, and detailTextLabel.text. There's white padding all around the cell. How do I get rid of the padding so all my images touch each other like the Youtube app below?

推荐答案

可能最简单的方法是子类 UITableViewCell -layoutSubviews 方法执行此操作：

Probably the easiest way to do this would be to subclass UITableViewCell and override the -layoutSubviews method to do something like this:

- (void)layoutSubviews {
  //have the cell layout normally
  [super layoutSubviews];
  //get the bounding rectangle that defines the position and size of the image
  CGRect imgFrame = [[self imageView] frame];
  //anchor it to the top-left corner
  imgFrame.origin = CGPointZero;
  //change the height to be the height of the cell
  imgFrame.size.height = [self frame].size.height;
  //change the width to be the same as the height
  imgFrame.size.width = imgFrame.size.height;
  //set the imageView's frame (this will move+resize it)
  [[self imageView] setFrame:imgFrame];

  //reposition the other labels accordingly
}
