CAKeyframeAnimation doesNotRecognizeSelector

Question

CAKeyframeAnimationで奇妙なエラーが発生しました。奇妙な部分は、 "SwiftDeferredNSArray doubleValue"です。なぜキーフレームアニメーションを扱うときにそれを取得できますか？

私はこれらのエラーで、以下のトレースを取得：要求として

-[_TtCs21_SwiftDeferredNSArray doubleValue]: unrecognized selector sent to instance 0x12b55e060

追加コード：

override func didUpdateFocusInContext(context: UIFocusUpdateContext, withAnimationCoordinator coordinator: UIFocusAnimationCoordinator) { 

    self.opacityView.layer.removeAnimationForKey("a") 

    if (self.focused) 
    { 
     self.opacityView.layer.addAnimation(a1, forKey: "a") 
    } 
} 


// Animation a1 
let ani = CAKeyframeAnimation(keyPath: "transform.scale") 
ani.timingFunctions = [CAMediaTimingFunction(controlPoints: 0.06,0.756,0.223,1.0)] 
ani.values = [[1.0,1.0,1.0],[1.0*scaleFactor,1.0*scaleFactor,1.0*scaleFactor]] 
ani.duration = 0.267 
ani.fillMode = kCAFillModeForwards 
ani.removedOnCompletion = false 

Answer 1

を、私はこれは少し遅れているけど、私はとにかく答えを与えるだろう考え出しこのエラーに遭遇している他の人々のために。私が見る限り、ani.valuesは配列の配列ではなく個々のキーフレーム値の配列でなければならないため、これを見ていると思います。例：

ani.values = [1.0, 1.0*scaleFactor]
