I have a navigational based application which has multiple views. Is it possible to use one single NSMutableArray for the whole applicaiton? Can i add objects to that NSMuta
The AppDelegate approach should work, and you should probably figure out why it's not working, even if you go with a singleton.
The statement to get your appDelegate pointer appears to be correct, so I'm guessing that the pointer to the array is either not getting set (and retained) in your myappDelegate class, or you did not create the AppDelegate instance correctly in the first place.
