//速度控制函数(CAMediaTimingFunction)
//1> kCAMediaTimingFunctionLinear（线性）：匀速，给你一个相对静态的感觉
//2> kCAMediaTimingFunctionEaseIn（渐进）：动画缓慢进入，然后加速离开
//3> kCAMediaTimingFunctionEaseOut（渐出）：动画全速进入，然后减速的到达目的地
//4> kCAMediaTimingFunctionEaseInEaseOut（渐进渐出）：动画缓慢的进入，中间加速，然后减速的到达目的地。
//移动简单的移动外还有启动的动画，只需要修改keyPath值就行
//@"position":位置移动
//@"transform.scale":缩放
//@"transform.rotation.x":x轴旋转
//@"transform.rotation.y":y轴旋转
//@"transform.rotation.z":z轴旋转
//默认以layer中心为圆心，可以通过下面方式修改
//[yourView.layer setAnchorPoint:CGPointMake(0.5, 0.5)];
//组合动画
//
///* 动画组 */
//CAAnimationGroup *group = [CAAnimationGroup animation];
//group.delegate = self;
//group.duration = 5.0;

//
//// 动画结束后不变回初始状态
//group.removedOnCompletion = NO;
//group.fillMode = kCAFillModeForwards;
//
//// 添加动画
//group.animations = [NSArray arrayWithObjects:animation1, animation2, nil];
//[imageView.layer addAnimation:group forKey:@"move-rotate-layer"];
