Question

So im trying to skip my first viewcontroller if a NSUserDefaults key is found. But its not working. Is it smart to use a Segue for this? Im new to storybord.

Warning: Attempt to present on whose view is not in the window hierarchy!

Im using this code in the viewDidLoad of the first VC:

    if ([[NSUserDefaults standardUserDefaults] boolForKey:@"HasLaunchedOnce"])
    {

        NSLog(@"not first launch");
        [self performSegueWithIdentifier:@"SegueToNewTrackTraceVC" sender:self];


    }else{
        NSLog(@"First launch");
    }

    NSLog(@"initialViewController loaded");
}

Answer 1

You forgot to update the NSUserDefault after the first launch.

if ([[NSUserDefaults standardUserDefaults] boolForKey:@"HasLaunchedOnce"])
{

    NSLog(@"not first launch");
    [self performSegueWithIdentifier:@"SegueToNewTrackTraceVC" sender:self];


}
else
{
    NSLog(@"First launch");
    [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"HasLaunchedOnce"];
}
