Swift 3 - How do I create a prominent button on a tab bar (e.g. camera button) [duplicate]

Answer 1

One way is to simply add your UIButton on top of UITabBarController with the dummy center view controller.

Here I use storyboard and subclass UITabBarController to add that button:

This is my storyboard, note how the center view controller is just there for space:

With only those code and storyboard, this is the result:

Answer 2

One solution would be to create your own subclass of the TabBar or just create a generic UIView that has the same properties as a TabBar (e.g. array of buttons that get displayed inside the view at certain heights, with the center one with a different height or offset value).

Another route you could take is to search and find other frameworks that are out there to use that do the same sort of functionality. A quick search on cocoacontrols came up with a couple options, the one that looked closest to what you are looking for is the RaisedCenterTabBar.
