'How to get the height of the tabbar programmatically?

I've found out that the height of a UITabBar is 49px (or 50px, depending on the source).

Because I don't like to use too much hard-coded values in my code I was wondering if it is possible to retrieve the height of the tabbar programmatically.

Kind regards,
Niels R.

PS: The reason I'm asking is because I have a view controller (with a list view containing text fields) that is either simply pushed by the navigationcontroller (pushViewController) or presented as a modal (presentModalViewController). As soon as the keyboard show up, the size of the view is reduced, but I have to take into account that the tabbar is only visible when the view controller is pushed and not presented as a modal.

I don't totally understand your P.S., but you can do:

tabBarController?.tabBar.frame.size.height

Solution 2:[2]

If you want to get the standard height for the UITabBar control then you can do:

    UITabBarController *tabBarController = [UITabBarController new];
    CGFloat tabBarHeight = tabBarController.tabBar.frame.size.height;

prettier 

CGRectGetHeight(self.tabBarController.tabBar.frame)

Solution 4:[4]

check this in your vc

bottomLayoutGuide.length

In Swift 3, you can retrieve the height of the UITabBar with this code below.

self.tabBarController!.tabBar.frame.size.height

Which will return a CGFloat value of the height

If an object is based on UIView (which most visual elements in the library are), you can get the size from the ivar "frame".

Solution 7:[7]

UITabBar is inherited from UIView as long as you mhave access to your UITabBar instance you can access and modify the frame of UITabBar,

CGRect myRect = myTabBar.frame;

Solution 8:[8]

Try to use the intrinsicContentSize property of the tab bar like this

let tabBarHeight = self.tabBarController.tabBar.intrinsicContentSize.height
