我试图利用 ABPersonViewController 的简单性，同时稍微自定义它的外观以匹配我的应用程序的外观和感觉。
我对 ABPersonViewController 进行了子类化，并使用 this technique ，我循环遍历 ABPersonViewController 的 View 层次结构，这是我的输出:
UIView: 0x5a45d80; frame = (0 0; 320 416); autoresize = W+H; layer = >

甜甜的!所以我应该能够递归地循环遍历根 UIView 的 subview ，并改变我的内心内容。
问题是，执行此循环时，根 UIView 只显示一个 subview (ABPersonTableView)，我不能再深入了。
有什么想法吗？ ABPersonTableView 是一个隐藏其创建/包含的所有内容的私有(private)类吗？
我可以通过在递归循环中执行此操作来更改表格的背景颜色:
if ([subview isKindOfClass:[UITableView class]]) {
((UITableView *)subview).backgroundColor = [UIColor purpleColor];
}
但是，我无法访问任何 UILabels，因为我无法访问 ABPersonTableView 的任何 subview 。
有什么想法吗？
最佳答案
你被困住了，因为苹果只提供两种方法:
- Apple 的内置、自动、 super 简单的外观和感觉方式(不可自定义)
- 您可以通过对 AddressBook 的低级调用自行完成所有操作
ABPersonViewController 及其 subview 不应该被修改，并且这样做不能保证与 future 的软件更新一起使用。
原因是苹果想要一致的外观和感觉。
如果您确实需要匹配应用程序的外观和感觉，则必须采用上面的方法 2) 并从头开始重新实现整个过程。这不一定很难，但肯定很耗时。
