declare a NSMutablearray of uiimages globally

Question

I want to declare a global array so I can use this in all methods and every where in my app. I have two buttons which 1 shows the next image in the array and the other button shows the previous image shown. I want both buttons to use the same array.

NSMutableArray *images = [[NSMutableArray alloc] 
                          initWithObjects:@"Americans.png",
                                          @"Approach.png",
                                          @"Arianny.png",
                                          @"Atoms.png",
                                          @"Australia.png",nil];

You might want to take a look at this question. I'd suggest going with putting it in your AppDelegate or creating a singleton.

Yep, anchor the array in your app delegate or make it a singleton. – Hot Licks Jan 14 '12 at 04:33

You can use dispatch_once to allocate a static object:

static dispatch_once_t once;
static NSMutableArray * images;
dispatch_once(&once, ^ { images = /*blah*/; });

Generally you would wrap this in a function or a class method of a utility class.
