e可疑代码。对新的细节有什么见解吗？我替换了以下代码：UIView*view=[[UIView alloc]initWithFrame:self.frame]；view.backgroundColor=[UIColor colorWithPatternImage:[UIImage ImageName:@“cell_background_normal.png”]；self.backgroundView=视图；使用以下代码：[self-setBackgroundColor:[uicolorWithPatternImage:[UIImage imageNamed:@“cell_background_normal.png”]]；在定制我的自定义单元格时，我仍然不确定如何在代码中使用它，因为我有一个需要添加的CAGradientLayer。不管怎样，我已经放弃了渐变，因为当我删除它时，删除按钮是可见的，单元格的纯白色外观与iOS7的设计模式相匹配。谢谢你的帮助！很好的解决方案。这是防止重新覆盖删除按钮的方法。在iOS6中，我曾将左侧的删除控件从（-）更改为（I），但现在行会滑动。有没有一种简单的方法可以在iOS7中保留iO6的方式，或者我只需要接受我的行的一部分在滑动时会被隐藏。你能简单地解释一下吗。如何在自定义单元格和默认单元格中对背景视图进行子类化。不幸的是，对于自定义格式的单元格，这使单元格上的文本不可见-在这篇描述修复的文章中可以看到正在发生的事情：我尝试了这个，我知道代码正在运行，但是我的删除按钮仍然在消失。
