iOS核心动画详解swift版---基础动画

• 创建工程,添加2个ViewController,通过rootViewController设置显示的ViewController
• 第一个ViewController实现基础动画 ####1.position动画,通过移动position移动位置 实现代码如下:

func position() {// 声明一个基础动画let ani = CABasicAnimation(keyPath: "position")// 设置动画toValue,也就是要移动到那个位置ani.toValue = NSValue(CGPoint: CGPointMake(300, 300))// 设置动画曲线:线性/先快后慢/先慢后快等ani.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)// 代理ani.delegate = self// 设置动画结束后不移除,需要以下2个属性设置共同完成ani.removedOnCompletion = false;ani.fillMode = kCAFillModeForwards;// 添加动画self.testView.layer.addAnimation(ani, forKey: nil)
}

####2.rotation动画,实现通过x,y,z轴的旋转 实现代码如下:

func rotationX() {let ani = CABasicAnimation(keyPath: "transform.rotation.x")ani.toValue = NSNumber.init(double: M_PI)ani.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)ani.delegate = selfani.removedOnCompletion = false;ani.fillMode = kCAFillModeForwards;self.testView.layer.addAnimation(ani, forKey: nil)
}

####3.scale动画,放大或者缩小一定的倍数 代码如下:

func scale() {let ani = CABasicAnimation(keyPath: "transform.scale")ani.toValue = NSNumber(int: 2)ani.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)ani.delegate = selfani.removedOnCompletion = false;ani.fillMode = kCAFillModeForwards;self.testView.layer.addAnimation(ani, forKey: nil)
}

####4.translation动画,直接移动到某个位置(与position对比) 代码如下:

func translation() {let ani = CABasicAnimation(keyPath: "transform.translation")ani.toValue = NSValue(CGPoint: CGPointMake(-50, -50))ani.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)ani.delegate = selfani.removedOnCompletion = false;ani.fillMode = kCAFillModeForwards;self.testView.layer.addAnimation(ani, forKey: nil)
}

####5.opacity动画,透明度/模糊度 代码如下:

func opacity() {let ani = CABasicAnimation(keyPath: "opacity")ani.toValue = NSNumber.init(float: 0.3)ani.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)ani.delegate = selfani.removedOnCompletion = false;ani.fillMode = kCAFillModeForwards;self.testView.layer.addAnimation(ani, forKey: nil)
}

####6.cornerRadius,borderWidth动画:设置圆角,以及边框宽度(需要设置view的layer.masksToBounds) 代码如下:

// 圆角
func cornerRadius() {let ani = CABasicAnimation(keyPath: "cornerRadius")ani.toValue = NSNumber.init(float: 50)ani.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)ani.delegate = selfani.removedOnCompletion = false;ani.fillMode = kCAFillModeForwards;self.testView.layer.addAnimation(ani, forKey: nil)
}
// 边框宽度
func borderWidth() {let ani = CABasicAnimation(keyPath: "borderWidth")ani.toValue = NSNumber.init(float: 2)ani.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)ani.delegate = selfani.removedOnCompletion = false;ani.fillMode = kCAFillModeForwards;self.testView.layer.addAnimation(ani, forKey: nil)
}

####7.contents动画,修改view的内容 代码如下:

func contents() {let ani = CABasicAnimation(keyPath: "contents")ani.toValue = UIImage.init(named: "12.png")?.CGImageani.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)ani.delegate = selfani.removedOnCompletion = false;ani.fillMode = kCAFillModeForwards;self.testView.layer.addAnimation(ani, forKey: nil)
}

###最后是动画的代理方法

// MARK: - 代理方法
// 动画开始
override func animationDidStart(anim: CAAnimation) {print("动画开始")
}
// 动画结束
override func animationDidStop(anim: CAAnimation, finished flag: Bool) {print("动画结束")dispatch_after(dispatch_time(DISPATCH_TIME_NOW,Int64(3.0 * Double(NSEC_PER_SEC))), dispatch_get_main_queue()) {self.testView.layer.removeAllAnimations()print("删除动画")}
}
