How to make a rounded oval button?

问题

My goal is to make my button look like this:

minus the black edges around the button.

After reading quite a few posts, I see most solutions saying to use

layer.cornerRadius = 10.0

When I do that I get this:

It rounds the edges, but doesn't give me my desired goal.

Any suggestion?

Swift 3

myButton.layer.cornerRadius = myButton.frame.height / 2

myButton.backgroundColor = UIColor.blue
myButton.clipsToBounds = true
myButton.tintColor = UIColor.white
myButton.setTitle("Connect With Facebook", for: .normal)

You Can do it like this (For Example if you button is called button):

button.layer.cornerRadius = button.bounds.size.height / 2.0
