Question

If the user gets impatient and touches this button before the next view can load, I get nested view issues, why isn’t this working? I assumed that turning the button BOOL enabled to no would fix it, but it doesn’t.

-(IBAction)start:(id)sender
{
    startButton.enabled = NO;
    [activity startAnimating];
    [locationManager stopUpdatingLocation];
    ViewController *view = [[ViewController alloc]init];
    NSManagedObjectContext *context = [self managedObjectContext];
    view.managedObjectContext = context;
    [self.navigationController pushViewController:view animated:YES];
}

Answer 1

That OP code should work. Ensure startButton is the correct button and connected in IB.

If the action is caused by the button you want to disable then self.enabled = NO; is more direct.
