iphone - 删除 UITableViewCell 上的填充

Question

在具有 UITableViewCellStyleSubtitle 样式的 UITableViewCell 上，我设置 imageView.image、textLabel.text和 detailTextLabel.text。细胞周围有白色填充物。如何去掉填充，使所有图像相互接触，就像下面的 Youtube 应用程序一样？

可能最简单的方法是子类化 UITableViewCell 并重写 -layoutSubviews 方法来执行以下操作:

- (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
}
