Question

I have a tab bar controller with a view inside a navigation controller. One of the buttons on this pops up a modal view. I set my starting view as the delegate for the modal, and call the following:

- (void)dischargeSaveComplete:(dischargeView *)controller
{
    [self dismissViewControllerAnimated:YES completion:nil];

    [self.navigationController popViewControllerAnimated:YES];
}

It correctly dismisses the modal view, but it doesn’t call the back button. Do I need to do something else since it’s inside a tab bar controller?

I tried set both to animation no as seen below, and it doesn’t work either.

- (void)dischargeSaveComplete:(ehrxEncounterDischargeView *)controller
{
    [self dismissViewControllerAnimated:NO completion:nil];

    [self.navigationController popViewControllerAnimated:NO];
}

Found the solution based on one of the answers, because I was in a tab bar controller, I had to call the popviewcontroller from the first view as seen below:

- (void)dischargeSaveComplete:(ehrxEncounterDischargeView *)controller
{
    [self dismissViewControllerAnimated:YES completion:^(void) 
    {
        demoView *e = [self.parentViewController.tabBarController.viewControllers objectAtIndex:0];
        [e.navigationController popViewControllerAnimated:YES];
    }];
}

You want 2 animations to follow one another, which is not allowed as you did it. You either have to cancel one of the animation or place popViewController inside the completion block for your first animation.

[self dismissViewControllerAnimated:YES completion:^(void) {
    [self.navigationController popViewControllerAnimated:YES];
}
];
