Question

I’m unable to refer to my integer pickedItem declared in my RootViewController.h in my DetailViewController.m file.

Not sure if I should declare this as a global variable, but tried unsuccessfully to do so.

I think this should be simple, but I haven’t got any other suggestions (from other posted answers) to work.

Thanks in advance.

Answer 1

You can access the app delegate through

[[UIApplication sharedApplication] delegate]

this call. And then can access the root view controller’s property (assuming you have access to the rootViewController object in appDelagate).

In RootViewController.h

@property(nonatomic, assign) NSInteger myInt

And from anywhere in the code

UIApplicationDelegate *delegate = [[UIApplication sharedApplication] delegate];
delegate.viewController.myInt = 31;

p.s. I have just typed the code, not compiled. So there might be some typo.
