Question

.hidesBottomBarWhenPushed = NO; doesn’t work because the view isn’t getting pushed. I want the tabBar to be hidden on the first screen and able to show it again a few screens later.

How can I do this?

Answer 1

Subclass your UITabBarController and add a function like this

- (void) hideTabBar:(BOOL)hide animated:(BOOL)animated {

    if (tabBarHidden == hide) { return; }

    if (animated) {
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:1.5];
    }

    for(UIView *view in self.view.subviews) {

        if([view isKindOfClass:[UITabBar class]]) {

            if (!hide) {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y-49, view.frame.size.width, view.frame.size.height)];
            } else {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y+49, view.frame.size.width, view.frame.size.height)];
            }
        } else {
            if (!hide) {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height-49)];
            } else {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height+49)];
            }

        }
    }

    if (animated) { [UIView commitAnimations]; }

    tabBarHidden = hide;

}   

Whilst your at it, add a function like this to allow the tab bar to rotate

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return allowRotate;
}
