Swift3に次のアニメーションを変換するには?NSValue valueWithCATransform3D:Swift3内
CABasicAnimation *scaleAnimation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
scaleAnimation.fromValue = [NSValue valueWithCATransform3D:CATransform3DIdentity];
scaleAnimation.toValue = [NSValue valueWithCATransform3D:CATransform3DMakeScale(2.5, 2.5, 1)];
私が現在持っていることは
let circleEnlargeAnimation = CABasicAnimation(keyPath: "transform.scale")
circleEnlargeAnimation.fromValue = CATransform3DIdentity
circleEnlargeAnimation.toValue = CATransform3DMakeScale(10.0, 10.0, 1.0)
あるしかし、私のアニメーションが動作していない...次は、フルアニメーションのコードです:
let shapeLayer = CAShapeLayer()
let center = CGPoint(x: sampleButton.bounds.width/2.0, y: sampleButton.bounds.height/2.0)
let radius = CGFloat(10.0)
let path = UIBezierPath(arcCenter: center, radius: radius, startAngle: 0.0, endAngle: (CGFloat(360.0 * M_PI)/180.0), clockwise: true)
shapeLayer.path = path.cgPath
shapeLayer.fillColor = UIColor.white.cgColor
shapeLayer.strokeColor = UIColor.white.cgColor
shapeLayer.lineCap = kCALineCapRound
shapeLayer.frame = sampleButton.bounds
let circleEnlargeAnimation = CABasicAnimation(keyPath: "transform.scale")
circleEnlargeAnimation.fromValue = CATransform3DIdentity
circleEnlargeAnimation.toValue = CATransform3DMakeScale(10.0, 10.0, 1.0)
circleEnlargeAnimation.duration = 1.0
shapeLayer.add(circleEnlargeAnimation, forKey: nil)
sampleButton.layer.addSublayer(shapeLayer)
それが唯一のサークルを示すがありますアニメートしないでください。
