IOS - Affordable Modal Parental Property

Question

I probably come across this too often, but is there a way to access the modal parent property?

So, I call "presentModalViewController" and then I can access some properties on the view controller that just called it from the modal.

Thanks Ashley

if you are using iOS 5, you can call self.presentingViewController to access the parent view controller

- presentingViewController, parentViewController, ( , , ), .

, - , presentingViewController.

, , , , , , .

:

((pController *)self.parentViewController).testString;

, UIViewController, , UITabBarController, selectedViewController .

modal.h

id delegate;

@property (nonatomic, assign) id delegate;

alloc/init modalViewController,

modalViewController.delegate = self;

That way I could call self.delegate from my modal. This was not enough, since it does not say which view controller it is, so I can’t say

self.delegate.testString;

But the casting, which I learned earlier, allowed me to get a fully working solution

((pController *)self.delegate).testString;

Hopefully I didn’t just blabber along this path, and I hope that this can help someone in the future.
