Question

So I’ve noticed some very weird behaviour from my program. Here’s a simplified code snippet and then I’ll explain what occurs when built and ran.

-(void)viewDidLoad {
   [super viewDidLoad];
   ...
   if (self.sampleBool) {
       [self performSegueWithIdentifier:@"mySegue" sender:self];
   }
   else {
       // do stuff
   }
}
...
-(IBAction)myMethod:(UITapGestureRecognizer*)sender {
    ...
    [self performSegueWithIdentifier:@"mySegue" sender:self];
}

The segue triggers via the UITapGestureRecognizer fine – so I know the segue is linked correctly. However, when self.sampleBool is true and performSegueWithIdentifier is called within viewDidLoad, the segue does not fire.

Anyone have any guesses? Any help or advice is appreciated.

Thanks

Answer 1

Try using viewWillAppear orviewDidAppear event and see if it works. My guess is that segues in viewDidload may not be relevant since things are not entirely wired up.

On the other hand, is there a design issue here? Should that segue be occurring at all if your condition is true? Perhaps you can do your test further upstream before that view is called to load.
