Snapchat-like text on image

Question

I have been trying to implement a Snapchat-like edit text on an image. What I did so far is implement a UILabel in the center of the UIImageView and I added 3 gestures to this U

Found a solution, apparently all I needed to do in the Rotation & Pinch is to always reset the view's rotation / scale. For instance, setting my recognizer.scale to 1.0 and recognizer.rotation to 0.0.

Here is an example of my code:

func handlePan(recognizer: UIPanGestureRecognizer) {
    let translation = recognizer.translationInView(view)
    if let view = recognizer.view {
        view.center = CGPoint(x:view.center.x + translation.x,
            y:view.center.y + translation.y)
    }
    recognizer.setTranslation(CGPointZero, inView: view)
}

func handlePinch(recognizer: UIPinchGestureRecognizer) {
    if let view = recognizer.view as? UILabel {
        let pinchScale: CGFloat = recognizer.scale
        view.transform = CGAffineTransformScale(view.transform, pinchScale, pinchScale)
        recognizer.scale = 1.0
    }
}

func handleRotate(recognizer: UIRotationGestureRecognizer) {
    if let view = recognizer.view as? UILabel {
        let rotation: CGFloat = recognizer.rotation
        view.transform = CGAffineTransformRotate(view.transform, rotation)
        recognizer.rotation = 0.0
    }
}
