在ViewController iOS中翻转TabBar和subView

Question

I am working on an app which is using UITabBarController . At some point, I have to flip the view and the whole tabbar and also have to update the tabbar items.

To flip the views without tabbar , I have used this:

-(IBAction)flipView:(id)sender {

    if (self.isSignUpViewOnDisplay == YES) {

        [self.signUpView setHidden:YES];
        [self.signUpView setHidden:NO];

        [UIView transitionFromView:self.signUpView toView:self.signInView
                          duration:1.0
                           options:UIViewAnimationOptionTransitionFlipFromRight | UIViewAnimationOptionShowHideTransitionViews
                        completion:NULL];
        self.isSignUpViewOnDisplay = NO;
    }
    else {

        [self.signUpView setHidden:NO];
        [self.signUpView setHidden:YES];

        [UIView transitionFromView:self.signInView toView:self.signUpView
                          duration:1.0
                           options:UIViewAnimationOptionTransitionFlipFromLeft | UIViewAnimationOptionShowHideTransitionViews
                        completion:NULL];
        self.isSignUpViewOnDisplay = YES;
    }
}

And it works perfectly. Now, I am inside a tabbar and I have to flip it. By using same code, I cannot see the flip animation. Although, tabbar is updated and its simple.

How I can flip the whole tabbar with current controller?

Answer 1

You can simply flip it with tabBarController.tabBar

UIView * a = self.tabBarController.tabBar;

[UIView transitionFromView:toolbar
                    toView:a
                  duration:0.5
                   options:UIViewAnimationOptionTransitionFlipFromTop | UIViewAnimationOptionShowHideTransitionViews
                completion:^(BOOL finished)
 {

 }];
