I tried to move segue continually, but I failed, too.
So I tried to set interval between first segue and second segue for one second.
This works well ! When you push button in red window, green window appears, and after it, blue window appears automatically.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self performSelector:@selector(segue) withObject:nil afterDelay:1.0];
}
- (void)segue
{
[self performSegueWithIdentifier:@"toBlue" sender:self];
}
