如何打印特定视图控制器的视图层次结构？(How to print view hierarchy of a specific view controller?)

如何打印特定视图控制器的视图层次结构？(How to print view hierarchy of a specific view controller?)

我在控制台中发出以下调用并获得视图层次结构。

（lldb）expr -l objc ++ -O - [[[UIWindow keyWindow] rootViewController] _printHierarchy]

<TestViewController 0x13ee07360>, state: appeared, view: <TestView 0x13ed10520> | <MyApp.MenuController 0x13ee126b0>, state: disappeared, view: (view not loaded) | <UINavigationController 0x13ee15b60>, state: appeared, view: <UILayoutContainerView 0x13ed16b80> | | <MyApp.ViewController 0x13ee13b50>, state: appeared, view: <UIView 0x13ee1d700>

如何打印MyApp.ViewController的视图层次结构？ 可以以某种方式使用视图控制器的地址吗？

I issue the following call in the console and got the view hierarchy.

(lldb) expr -l objc++ -O -- [[[UIWindow keyWindow] rootViewController] _printHierarchy]

<TestViewController 0x13ee07360>, state: appeared, view: <TestView 0x13ed10520> | <MyApp.MenuController 0x13ee126b0>, state: disappeared, view: (view not loaded) | <UINavigationController 0x13ee15b60>, state: appeared, view: <UILayoutContainerView 0x13ed16b80> | | <MyApp.ViewController 0x13ee13b50>, state: appeared, view: <UIView 0x13ee1d700>

How do I print the view hierarchy for MyApp.ViewController? Can the address of the view controller be used somehow?

最满意答案

只需输入lldb命令即可

expr -l objc++ -O -- [0x13ee13b50 _printHierarchy]

其中0x13ee13b50是您感兴趣的视图控制器的地址。

Just enter the lldb command

expr -l objc++ -O -- [0x13ee13b50 _printHierarchy]

where 0x13ee13b50 is the address of the view controller that you are interested in.
