Answer 1

If you're using Interface Builder:

1. Drag a UIButton to the view
2. Set the size constraints (ex: width 80, height 80)
3. Align Center X to Superview
4. Align Bottom to Tab Bar: -20

In your View Controller:

1. Add an IBOutlet for the button

2. Then in viewDidLoad under super.ViewDidLoad() add:

   button.layer.zposition = 1

It should give you this result:

You can lower the image by increasing the negative number on the bottom constraint.
