This class is used for Easing animation.

• Easy to understand
• You can use it to build your own animation

 

How to use

• Import the header

  and use like this:

 // 计算好起始值,结束值

 CGFloat oldValue = 0.f;

 CGFloat newValue = 1.f;



 // 关键帧动画

 CAKeyframeAnimation *animation = \

     [CAKeyframeAnimation animationWithKeyPath:@"transform.rotation.z"];



 // 设置值

 [animation setValues:[YXEasing calculateFrameFromValue:oldValue

              toValue:newValue

                 func:ElasticEaseOut

           frameCount:500]];



 // 设置持续时间

 animation.duration  = 0.5f;



 // 每秒增加的角度(设定结果值,在提交动画之前执行)

 layer.transform = \

     CATransform3DMakeRotation(newValue, 0.0, 0.0, 1.0);



 // 提交动画

 [layer addAnimation:animation forKey:nil];

enjoy it :)
