Question

Hey everyone,
I am trying to iterate though an array of strings when I click a button in my iPhone app. In the viewDidLoad method this code works great, however, I am using a Tab Bar to switch between views, and I want the view to refresh itself when i switch to it from another view. This is the code it is breaking around, very similar to code I am using in another button that works perfectly

        NSEnumerator *e = [deckList objectEnumerator];
        id obj;

It crashes whenever it gets to “id obj”
Any help would be most appreciated.

for (NSString* string in arrayOfStrings ){
    NSLog(@"%@", string);
}
