Strange animation on iOS 7 when using hidesBottomB

Question

This problem comes when I build an app targeting iOS 5 or 6, but run it on iOS 7. If I have a controller in a navigationController that is a part of a tabBarController, and I do the following:

controller.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:testController animated:YES];

A strange vertical positioning animation occurs. I would instead like the new controller (with the bottom bar hidden) to push or pop on the navigation controller pushing the tab bar out or bringing it back and with no vertical positioning changes.

Answer 1

Just set the translucent property to NO for both navigation bar and tabBarController. This will solve your problem.

Answer 2

Try This:

[self.navigationController.navigationBar setHidden:NO];

Answer 3

If you want to keep transparency, add this to the root UIViewController:

- (void)viewWillAppear:(BOOL)animated {
    [UIView animateWithDuration:0.35f animations:^{
        self.tabBarController.tabBar.alpha = 1.0f;
    }];
}

- (void)viewWillDisappear:(BOOL)animated {
    [UIView animateWithDuration:0.35f animations:^{
        self.tabBarController.tabBar.alpha = 0.0f;
    }];
}

This way you'll get a nice fade-in/fade-out animation of the tab bar.

Answer 4

this says you should put:

self.navigationController.navigationBar.translucent = NO;

Answer 5

Try this

if( [self respondsToSelector:@selector(setEdgesForExtendedLayout:)] )
{
    self.edgesForExtendedLayout=UIRectEdgeNone;
}

Answer 6

You can always remove animation from the UIView with

[self.view.layer removeAllAnimations];
