Question

I’m new to iphone development, and just to get a feel for it, I created a new view which has an alert popup on every load.

This works correctly, however when i shut the app down, then reopen it, the whole app crashes. The only thing I’m doing is showing an alert.

This is my code of the alert:

    UIAlertView *alert = [[UIAlertView alloc]
                      initWithTitle: @"Announcement"
                      message: @"This is really annoying just to make"
                      delegate: nil
                      cancelButtonTitle:@"OK"
                      otherButtonTitles:nil];
[alert show];

I think I’m supposed to put [alert release]; but Xcode keeps saying that release is unavailable.

Is the [alert release] the reason my app keeps crashing on exit/restart?

Thanks!

Edit: Heres the surrounding code where I call UIAlertView

- (void)viewDidLoad
{
    [super viewDidLoad];
// Do any additional setup after loading the view.

//just testing alerts..this shows up after the first load only
UIAlertView *alert = [[UIAlertView alloc]
                      initWithTitle: @"Announcement"
                      message: @"This is really annoying just to make"
                      delegate: nil
                      cancelButtonTitle:@"OK"
                      otherButtonTitles:nil];
[alert show];

}

release will be unavailable if you use ARC

Also, It is pretty unusual for a simple alert to cause a crash, as @rdelmar said in the comments, you really need to provide more info about your problem… One thing you could try though is to display your UIAlertView inside viewDidAppear instead of the viewDidLoad method.
