我有这个奇怪的问题，我的桌子重叠的UITableViewCell - 与以往的细胞内容
- 我有大约20个细胞显示
- 每个单元的高度为
- 约84px当我点击任何单元格，我已经设置了背景颜色
- 前4个单元格都可以，但是当我向下滚动并单击第5个单元格时，每个单元格的内容开始与其他一些内容重叠，通常是来自第4个单元格的内容。
我相信它的一些细胞可重用性或绘图问题。我不确定如何解决它，我检查了我的代码，但我没有改变单元格的内容。
这里是我的代码，将增加一些照片太

return 104;
}

你应该在nib中构建像这样的单元格，而不是在cellForRow中创建所有的东西。 – Mark 2013-04-23 22:07:09
你也可以在这里看到答案。清楚地解释。 http://stackoverflow.com/questions/8999300/labels-in-custom-cell-overlaps – user3675974 2014-07-09 07:36:17
我有同样的问题，但我的子视图没有在代码中实例化，但来自故事板。如果删除子视图，他们都会消失。我该如何解决这个问题？ – DamirDiz 2015-07-27 16:29:39
