Question

So i am new to iOS programming. I am using SDK 4.0 and you know when you build a universal project they provide you with app delegates for the full project and two sub class app delegates classes for iphone and ipad.

Question is how will i call app delegate method from the sub class app delegate class that is extending the app delegate.

Like this

#import "AppDelegate.h"


@interface AppDelegate_iPhone : AppDelegate 
{
   // have to call the AppDelegate methods and its objects.


}

You can send messages to the parent/super class using super like [super doThisMethod];. If you have to use the ivars or properties declared in the superclass, you can directly refer to them as they were declared in your class – ivar or self.property.

But you should read Apple's guide on Objective-C first. It is pretty well documented.
