How does one access a super's view controller?

Question

Hi guys!

I have a problem and I will try to explain the issue:

• I have one main UIViewController (Whole screen)
• I have one secondary UIViewController (setbounds)

• I added my secondary view to my mainview using this:

  [mainController.view addSubview:secondaryController.view];

• I created a third controller: modalController, i added it to my secondary controller like this:

  [secondaryController presentModalViewController:modalController animated:YES];

• I make calculus based on some events inside of my modelController.

• Im able to send messages from my modalController to my secondaryController using:

[[self parentViewController] performSelector:@selector(myMethodInSecondaryController:) withObject:myObject afterDelay:.5];

NOTE: "self" corresponds to the modalController

• I need to pass "myObject" to my mainController, but i cant make reference to my mainController from the secondaryController. I tried this:

[[self parentViewController] performSelector:@selector(myMethodInMainController:) withObject:myObject afterDelay:.5];

NOTE: "self" corresponds to the secondaryController

but it doesn't work, i have access to my mainController's view using:

self.view.supperview

NOTE: "self" is my secondaryController

but no to it's controller.

Thanks in advantage for your help. Alejandra :)

In your secondary controller, try

id mainViewController = [self.view.superview nextResponder];

and see if this is the main view controller you're looking for.
