帶#keyPath的CATransform3D關鍵路徑

Question

是否可以使用增強關鍵路徑（如here）針對Swift 3中的CATransform3D屬性和新的#keyPath關鍵字？

換句話說東西來代替

let scaleAnimation = CABasicAnimation(keyPath: "transform.scale") 

像

let scaleAnimation = CABasicAnimation(keyPath: #keyPath(CALayer.transform.???)) 

Answer 1

恕我直言CAValueFunction應使用，但對我來說不能很好地工作......

let scaleAnimation = CABasicAnimation(keyPath: "transform.scale") 

- >

let scaleAnimation = CABasicAnimation(keyPath: #keyPath(CALayer.transform)) 
scaleAnimation.valueFunction = CAValueFunction(name: kCAValueFunctionScale) 

和

let rotationAnimation = CABasicAnimation(keyPath: "transform.rotation") 

- >

let rotationAnimation = CABasicAnimation(keyPath: #keyPath(CALayer.transform)) 
rotationAnimation.valueFunction = CAValueFunction(name: kCAValueFunctionRotateZ) 

等

• rotation.x - >kCAValueFunctionRotateX
• rotation.y - >kCAValueFunctionRotateY
• rotation.z - >kCAValueFunctionRotateZ
• rotation - >kCAValueFunctionRotateZ
• scale.x - >kCAValueFunctionScaleX
• scale.y - >kCAValueFunctionScaleY
• scale.z - >kCAValueFunctionScaleZ
• scale - >kCAValueFunctionScale
• translation.x - >kCAValueFunctionTranslateX
• translation.y - >kCAValueFunctionTranslateY
• translation.z - >kCAValueFunctionTranslateZ
• translation - >kCAValueFunctionTranslate
