CABasicAnimation unlimited repeat without HUGE_VALF?
No, this is the way you're supposed to do it according to the documentation.
Setting this property to
HUGE_VALFwill cause the animation to repeat forever.
Update for Swift:
HUGE_VALF is not exposed to Swift. However, my understanding from this page is that HUGE_VALF is intended to be infinity (in fact, INFINITY is defined as HUGE_VALF). Since Swift's FloatingPointType protocol provides a static var infinity, you can simply write
myAnimation.repeatCount = .infinity
For swift 3.0 and above
let rotationAnimation = CABasicAnimation(keyPath: "transform.rotation.z") rotationAnimation.fromValue = 0 rotationAnimation.toValue = CGFloat.pi * 2 rotationAnimation.duration = 1 rotationAnimation.repeatCount = .infinity holderView.btnRefresh.layer.add(rotationAnimation, forKey: "spinAnimation")
