Ios 将单元格添加到UITableView，但它们没有'；我无法直观地显示，但我可以单击，它们可以工作

将iOS6应用程序迁移到iOS7，这在以前是可行的。在6点，一切正常

在iOS7上，当向UITableView添加单元格时，它们不会直观地显示出来，但当我单击它们应该在的位置时，它们会像在那里一样工作

好像UIView没有重新绘制自己或其他东西。很奇怪

有人知道从哪里开始找吗

执行递归描述我得到了这个

看起来所有的都是可见的，所以这个订单是正确的。因此，我猜当我单击一个空的tableviewcell（即没有数据），但只有一个没有分隔符的背景图像（即，它看起来平坦平滑）时，会发生什么。它仍然让我选择它，好像它是一个好的细胞

所以有两个问题

提供给此tableview的字典的新数据要么没有数据，要么有数据，并且没有重新绘制

它允许我点击空单元格，这是我不希望发生的

---

尝试将断点放置在类似于

didselectrowatinexpath

的位置，然后键入

po[self.tableView recursiveDescription]

以查看视图层次结构的外观。您的单元格似乎是空的，或者布局是这样的，以至于内容不在屏幕上。然后返回报告，请为您的问题添加更多详细信息，例如代码和屏幕截图（它应该是什么样子，而您得到的是什么），等等。

iOS 7中更改了UITableView的内部结构。这在任何地方都没有记录，因为只要使用公共API（将内容添加到

contentView

，而不是直接添加到

cell

）就没有副作用

---

如果从单元格内部执行类似于

self.superview

的操作，则会出现问题，因为视图层次结构不是由公共API定义的。

滚动tableview时会发生什么情况？请检查对象的颜色。因为如果对象为白色，则ios7中单元格的默认颜色将设置为白色，这意味着在滚动对象时它将不可见。背景是自定义图像，而不是白色。发布表数据源方法的源代码我没有收到更新，因为您没有回复我。如注释线程中所述，您的

recursiveDescription

显示内容视图中不包含单元格的内容。这是您的解决方案解决的问题。单元格在那里，但您无法看到它们，因为子视图不在contentView中。
