Question

I’ve been searching for a solution for this problem but I couldn’t solve it!
I tried

mapViewController = (MapViewController*)self.parentViewController;

but it doesn’t work.

Answer 1

you can do like this ..

in your class .h file

make a member variable

@interface SomeClass: NSObject
{

 UIViewController *controller;
}

when you initialize the class make it controller to self …that way it will work the same way as

SomeClass *class = [[SomeClass alloc]init];
class.controller = self;

now you can use the parent properties and methods..However you will still need to typecast it to (MapViewController*)controller so that it autocompletes its methods.
