I am pasting this from my working code... you can call these methods to hide and show the tabbarcontroller.... just pass tabbarcontroller instance to these functions..
1 // Method call 2 [self hideTabBar:self.tabBarController];
// Method implementations - (void)hideTabBar:(UITabBarController *) tabbarcontroller { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; for(UIView *view in tabbarcontroller.view.subviews) { if([view isKindOfClass:[UITabBar class]]) { [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)]; } else { [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)]; } } [UIView commitAnimations]; } - (void)showTabBar:(UITabBarController *) tabbarcontroller { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; for(UIView *view in tabbarcontroller.view.subviews) { NSLog(@"%@", view); if([view isKindOfClass:[UITabBar class]]) { [view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)]; } else { [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)]; } } [UIView commitAnimations]; }
Modified Setomidor's answer to work on both landscape, portrait, and iPad (the 320 and 480 values only work on iPhone).
- (void) hideTabBar:(UITabBarController *) tabbarcontroller { CGRect screenRect = [[UIScreen mainScreen] bounds]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; float fHeight = screenRect.size.height; if( UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) ) { fHeight = screenRect.size.width; } for(UIView *view in tabbarcontroller.view.subviews) { if([view isKindOfClass:[UITabBar class]]) { [view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)]; } else { [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)]; view.backgroundColor = [UIColor blackColor]; } } [UIView commitAnimations]; } - (void) showTabBar:(UITabBarController *) tabbarcontroller { CGRect screenRect = [[UIScreen mainScreen] bounds]; float fHeight = screenRect.size.height - 49.0; if( UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) ) { fHeight = screenRect.size.width - 49.0; } [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; for(UIView *view in tabbarcontroller.view.subviews) { if([view isKindOfClass:[UITabBar class]]) { [view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)]; } else { [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)]; } } [UIView commitAnimations]; }
Saurabh's answer above can be extended to also work in landscape orientation:
+ (void) hideTabBar:(UITabBarController *) tabbarcontroller { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; //Support for landscape views int orientation = [[UIDevice currentDevice] orientation]; int x_pos = 480; if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) { x_pos = 320; } for(UIView *view in tabbarcontroller.view.subviews) { if([view isKindOfClass:[UITabBar class]]) { [view setFrame:CGRectMake(view.frame.origin.x, x_pos, view.frame.size.width, view.frame.size.height)]; } else { [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, x_pos)]; } } [UIView commitAnimations]; }
Saurahb and karlbecker_com's solutions are great, though they can cause an obvious popping effect when the view contains a tableview while the tab bar animates back up. I've made some modifications and combined it into a single function (as a category on UITabBarController). It's not completely perfect (delayed correction animation) but gives good results with tables.
If you like animation blocks and categories, give this a try. Orientation and device friendly.
