Getting the frame of a particular tab bar item

Question

Is there a way to find the frame of a particular UITabBarItem in a UITabBar?

Specifically, I want to create an animation of an image \"falling\

Answer 1

You do not need any private API, just use the UITabbar property itemWidth and itemSpacing. Set these two values like following:

NSInteger tabBar.itemSpacing = 10; tabBar.itemWidth = ([UIScreen mainScreen].bounds.size.width - self.tabBarController.tabBar.itemSpacing * (itemsCount - 1)) /itemsCount;

Note this will not impact the size or position of image and title used for UITabBarItem.

And then you can get the ith item's center x like following:

CGFloat itemCenterX = (tabBar.itemWidth + tabBar.itemSpacing) * ith + tabBar.itemWidth / 2;
