Why cannot add method in category extension in objective-c?

With given class TestViewController, if a method is added to its extension. But error will pop up, what is the reason?

Code:

@interface TestViewController (){
    -(void) testMethod;
}

Parse error: TestViewController.m:12:5: Type name requires a specifier or qualifier

How to add a method to extension class which extend a anonymous category? thanks

Remove the {}. ivars are declared inside {}, methods are declared outside the {}.
