Question

我试图围绕它自己动画/旋转一个圆圈。是我试过的，但它只是在整个屏幕上旋转..我不需要它移动，我只需要在现场旋转。让circleLayer：CAShapeLayer！\在方法之外

        vlet rotate = CABasicAnimation(keyPath: "transform.rotation.z")
        rotate.fromValue = Float(0.0)
        rotate.toValue = Float(2.0 * M_PI)
        rotate.duration = 1.0
        rotate.cumulative = true
        rotate.repeatCount = 1
        rotate.removedOnCompletion = false
        rotate.fillMode = kCAFillModeForward
        circleLayer.addAnimation(rotate, forKey: "transform.rotation.z")

任何想法为什么它会在现场移动和旋转/旋转？

找到解决方案，我只是用不同的动画旋转视图本身：

 UIView.animateWithDuration(0.95, delay: 0.0, options: UIViewAnimationOptions.CurveLinear,      animations: { () -> Void in
            self.circleView.transform = CGAffineTransformMakeRotation(self.sumer)
        }, completion: nil)
