Poptorootviewcontroller with delay

Question

I have a method "test" that execute poptorootviewcontroller. I want to put some delay before the animation of poptorootviewcontroller. Here is my code :

-(void)test{
[UIView animateWithDuration:5.0
                      delay: 2.5
                    options: UIViewAnimationOptionCurveEaseIn
                 animations:^{
                     [self.navigationController popToRootViewControllerAnimated:NO];
                 }
                 completion:nil];
}

But it doesn't work. Any help? Thanks!

Answer 1

The code you posted is for performing an animation, not delaying.

A good solution would be to use dispatch_after:

-(void)test{
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
        [self.navigationController popToRootViewControllerAnimated:NO];
    });

Replace the 2.5 with whatever delay you want.
