iphone - 我需要检查 iPhone 程序上的 View 层次结构

Question

如何确定 iPhone 程序在模拟器上运行时的 View 结构？

Answer 1

有一种内置方法可以转储 View 层次结构:recursiveDescription

NSLog(@"%@", [查看递归描述]);

它会输出如下内容:

<UIView: 0x6a107c0; frame = (0 20; 320 460); autoresize = W+H; layer = […]
   | <UIRoundedRectButton: 0x6a103e0; frame = (124 196; 72 37); opaque = NO; […]
   |    | <UIButtonLabel: 0x6a117b0; frame = (19 8; 34 21); text = 'Test'; […]
