持续旋转

平面旋转：

顺时针旋转90度：

UIView.animate(withDuration: 1) {

self.captainLabel.transform = CGAffineTransform(rotationAngle: CGFloat.pi / 2)

}

顺时针旋转180度：

UIView.animate(withDuration: 1) {

self.captainLabel.transform = CGAffineTransform(rotationAngle: CGFloat.pi)

}

逆时针旋转90度：

需要用到

@available(iOS 2.0, *)

public func inverted() -> CGAffineTransform

事例代码

UIView.animate(withDuration: 1) {

self.captainLabel.transform = CGAffineTransform(rotationAngle: CGFloat.pi / 2).inverted()

}

持续旋转：

需要用到

@available(iOS 2.0, *)

public func concatenating(_ t2: CGAffineTransform) -> CGAffineTransform

事例代码

Timer.scheduledTimer(withTimeInterval: 1, repeats: true) { (_) in

UIView.animate(withDuration: 1) {

self.captainLabel.transform = CGAffineTransform(rotationAngle: CGFloat.pi / 2).inverted().concatenating(self.captainLabel.transform)

}

}

3D旋转：

需要用到

@available(iOS 2.0, *)

public func CATransform3DRotate(_ t: CATransform3D, _ angle: CGFloat, _ x: CGFloat, _ y: CGFloat, _ z: CGFloat) -> CATransform3D

向量为(1, 0, 0)时：

UIView.animate(withDuration: 1) {

self.captainLabel.layer.transform = CATransform3DMakeRotation(CGFloat.pi, 1, 0, 0)

}

向量为(0, 1, 0)时：

UIView.animate(withDuration: 1) {

self.captainLabel.layer.transform = CATransform3DMakeRotation(CGFloat.pi, 0, 1, 0)

}

向量为(0, 0, 1)时：

UIView.animate(withDuration: 1) {

self.captainLabel.layer.transform = CATransform3DMakeRotation(CGFloat.pi, 0, 0, 1)

}

持续旋转：

Timer.scheduledTimer(withTimeInterval: 1, repeats: true) { (_) in

UIView.animate(withDuration: 1) {

self.captainLabel.layer.transform = CATransform3DRotate(self.captainLabel.layer.transform, CGFloat.pi / 2, 1, 0, 0)

}

}
