自我控制器0键/值对

Question

I have a working controller, however when I debug it and try to see the values of the variables, self is empty like this. I tryed to clean project, restarted XCODE but nothing worked, any idea?

Answer 1

我刚刚创建了另一个控制器，复制并粘贴了所有内容，它才起作用

Answer 2

initialize you variable in viewDidLoad.

for ex. if you have declared NSMutableArray in properties and haven't intialized them in viewDidLoad. like this ieNSMutableArray a=[NSMutableArray alloc]init];

It may cause this problem.
