how Marquee text of label on swift?

Question

I want to create a marquee label in Swift. I tried some codes but could not get it to work.

I also can do this with animation but I have problem with repeating it.

Answer 1

I don't know why I got 2 - ?!???

I tried many things. that doesn't matter anymore...

I found this 5 min ago and thats my answer for using animation instead of marquee. but on iOS marquee is a tough problem !

here is the link that solved my repeating animation problem

I used this code and it Works ! wish to help others too.

on ViewdidLoad :

  if let aLabel = self.txtAmarFull {
        aLabel.pushTransition(3)

    }

on Body:

extension UIView {
func pushTransition(duration:CFTimeInterval) {
    let animation:CATransition = CATransition()
    animation.timingFunction = CAMediaTimingFunction(name:
        kCAMediaTimingFunctionEaseInEaseOut)
    animation.type = kCATransitionMoveIn
    animation.subtype = kCATransitionFromLeft
    animation.duration = duration
    animation.repeatCount = 99
    self.layer.addAnimation(animation, forKey: kCATransitionPush)
}

my label name is : txtAmarfull
