iPhone UILabel text soft shadow

Question

I know soft shadows are not supported by the UILabel out of the box, on the iPhone. So what would be the best way to implement my own one?

EDIT:

Answer 1

In Swift 3, you can create an extension:

import UIKit

extension UILabel {
    func shadow() {
        self.layer.shadowColor = self.textColor.cgColor
        self.layer.shadowOffset = CGSize.zero
        self.layer.shadowRadius = 3.0
        self.layer.shadowOpacity = 0.5
        self.layer.masksToBounds = false
        self.layer.shouldRasterize = true
    }
}

and use it via:

label.shadow()
