Hello all

I have a NSMutableArray *array; and assign this array a dictionary.

NSUserDefaults *defaults;
defaults = [NSUserDefaults standardUserDefaults];
array = [[defaults objectForKey:@"key"] retain];

But when the user start my app the first time, the array is (NULL) and it's
not possible to set any dict or object to the array.
How to fix that?
Thanks
David

Try something like this:

if (array == nil) {
NSMutableArray *myArray = [[NSMutableArray alloc] initWithSize:1];
[myArray addObject:myObject];
[defaults setObject:myArray forKey:@"key"];
[myArray release];
}

If you need to add more than one object, obviously, you would put the addObject message inside a loop of some kind.

Hope that helps!
