Use NSMutableArray in app delegate in another class

Question

I have an NSMutableArray in my app delegate. I wish to use that mutable array in a different class in my program, as if it were a global variable. How would I do this?

Is it as simple as importing the header and referencing the object?

Answer 1

Take advantage of the UIApplication singleton:

YourAppDelegate *appDelegate = (YourAppDelegate *)[[UIApplication sharedApplication] delegate];

Then, access your array property like this: appDelegate.yourArrayProperty
