NSMutableArray getting released before ViewDidLoad

In my header file I have:

@property (nonatomic, retain) NSMutableArray * array1;

and in My initWithNibName method I have:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
    // Custom initialization

    self.array1 = [[NSMutableArray alloc] initWithObjects:@"test", nil];


    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(DoUpdateLabel:) name:@"DoUpdateLabel" object:nil];

}
return self;
}

The DoUpdateLable method does some updating to the array (adds a number of items). Once this is complete and ViewDidLoad executes my array disappears and becomes null which is annoying because I want to load it into a table view.

Here's a trimmed down version of the DoUpdateLable method. I've had to trim it down as the actual method includes a lot of JSON parsing and URL requests:

-(void)DoUpdateLabel:(NSNotification *) notification
{   
int count = 0;
while(count < 59)
{
    NSString * currentpatname = @"test1";
    if(![currentpatname isEqualToString:@""])
    {
        [self.array1 addObject:currentpatname];
        NSLog(@"array: %@", self.array1);
    }
    count++;
}

NSLog(@"final array: %@", self.array1);
}

I'm a little stuck as to why it's not being retained. Any help would be much appreciated!

Thanks!

initWithNibName:bundle: is called if you just use alloc init somewhere. You probably have done that, but you shouldn't be. Delete that, and put the code you have in your question in initWithCoder:, then it should work properly.

Looking at your updated question, you're setting up that array inside the scope that starts with // Custom initialization. But what you don't notice is that viewDidLoad is actually called on this line: self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

That means your array is still nil inside viewDidLoad, and thus DoUpdateLabel

I would recommend instead initializing that array inside -viewDidLoad instead, and you'll see the results you're looking for.
