iPhone Dev - Storing and Retrieving Variables from App Delegate

Question

I have created a variable in my App Delegate and from my first View Controller, I am saving a value to the variable (in the App Delegate).

Here is how I'm saving the value to the variable in the App Delegate:

MyAppDelegate *DelegateVar = TheValue;

NSLog(@"%@", DelegateVar); // This NSLog outputs correct value

Later in the program, in a separate ViewController, I am trying to retrieve the value from the App Delegate. I am getting values that look to be pointers...

Here is how I'm trying to retrieve the value:

MyAppDelegate *MyVar = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];

NSLog(@"%@", MyVar); // outputs incorrect value

Anybody that has any input regarding my problem, your help would be greatly appreciated.

Answer 1

This doesn't make sense. Why are you assigning a value to a pointer to your application's delegate in the first place? If you want to assign a value to an instance variable inside your delegate, then you need to do something completely different.

Answer 2

First, you should check the main XIB file to ensure the delegate is wired up to the application.

Second, try replacing TheValue in the first instance with [[UIApplication sharedApplication]delegate] and see if you get the same incorrect value as you do later on.
