I want to increment UILabel.text value from 0 to say 100 using CoreAnimation with easing functions (e.g. easeInOutQuad). But it seems like text property is not animatable. So how to achieve this with the help of CA? Or Would I need to implement easing function myself and call it using GCD? Thanks
P.S. I'd like to stick to CA as much as possible.
class ViewController: UIViewController {
@IBOutlet weak var label: UILabel!
var counter = 0
override func viewDidLoad() {
super.viewDidLoad()
let timer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: Selector("animate"), userInfo: nil, repeats: true)
timer.fire()
}
func animate() {
UIView.transitionWithView(label,
duration: 1.0,
options: [.CurveEaseInOut],
animations: { () -> Void in
self.counter += 1
self.label.text = "\(self.counter)"
}, completion: nil)
}
}
