Change UITabBar height

Question

I use UITabBarController as a root view and app supports iOS 6 and above. Project class hierarchy is as below.

UITabBarController   - tab1     - UINavigationController       - UIViewController       - UIViewController       .       .   - tab2     - UINavigationController       - UIViewController       - UIViewController       .       .       .   - tab3     - UIViewController   - tab4     - UIViewController 

I used below code to change height of UITabBar in one of the UIViewControllers (which is inside UINavigationController) in above hierarchy.

CGRect tabbarFrame = self.tabBarController.tabBar.frame; tabbarFrame.size.height += 60; self.tabBarController.tabBar.frame = tabbarFrame; 

But its not changing the height. UITabBar is displayed with default height. Though logging its value prints changed value as shown below.

<UITabBar: 0xb528f60; frame = (0 431; 320 109); autoresize = W+TM; layer = <CALayer: 0xb529080>> 

How can I change UITabBar's height to achieve something like this:?

I faced this issue and I was able to solve it.

You have to add following code to your subclass of UITabBarController class.

const CGFloat kBarHeight = 80;  - (void)viewWillLayoutSubviews {     [super viewWillLayoutSubviews];      CGRect tabFrame = self.tabBar.frame; //self.TabBar is IBOutlet of your TabBar     tabFrame.size.height = kBarHeight;     tabFrame.origin.y = self.view.frame.size.height - kBarHeight;     self.tabBar.frame = tabFrame; } 

Swift:

override func viewWillLayoutSubviews() {     super.viewWillLayoutSubviews()      tabBar.frame.size.height = kBarHeight     tabBar.frame.origin.y = view.frame.height - kBarHeight }
