===永久闪烁的动画=====

-(CABasicAnimation *)opacityForever_Animation:(float)time
{
    //必须写opacity才行
    CABasicAnimation *animation =[CABasicAnimation animationWithKeyPath:@"opacity"];
    animation.fromValue =[NSNumber numberWithFloat:1.0f];
    animation.toValue =[NSNumber numberWithFloat:0.0f];//这是透明度
    animation.autoreverses = YES;
    animation.duration =time;
    animation.repeatCount =MAXFLOAT;
    animation.removedOnCompletion =NO;
    animation.fillMode =kCAFillModeForwards;
    animation.timingFunction =[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
    return animation;
}

======横向纵向移动=======

-(CABasicAnimation *)moveX:(float)time X:(NSNumber *)x
{
    CABasicAnimation *animation =[CABasicAnimation animationWithKeyPath:@"transform.translation.x"];
    animation.toValue =x;
    animation.duration =time;
    animation.removedOnCompletion =NO;
    animation.repeatCount =MAXFLOAT;
    animation.fillMode =kCAFillModeForwards;
    return animation;
}

=========缩放======

-(CABasicAnimation *)scale:(NSNumber *)Multiple orgin:(NSNumber *)orginMultiple durTimes:(float)time
                       Rep:(float)repertTimes
{
    CABasicAnimation *animation =[CABasicAnimation animationWithKeyPath:@"transform.scale"];
    animation.fromValue =Multiple;
    animation.toValue =orginMultiple;
    animation.autoreverses =YES;
    animation.repeatCount =repertTimes;
    animation.duration =time;
    animation.removedOnCompletion =NO;
    animation.fillMode =kCAFillModeForwards;
    return animation;
}

------组合动画

-(CAAnimationGroup *)groupAnimation:(NSArray *)animationArray durTimes:(float)time Rep:(float)repeatTimes
{
    CAAnimationGroup *animation =[CAAnimationGroup animation];
    animation.animations =animationArray;
    animation.duration =time;
    animation.removedOnCompletion =NO;
    animation.repeatCount =repeatTimes;
    animation.fillMode =kCAFillModeForwards;
    
    return animation;
}

-----路径动画-------

-(CAKeyframeAnimation *)keyframeAnimation:(CGMutablePathRef)path durTimes:(float)time Rep:(float)repeatTimes
{
    CAKeyframeAnimation *animation =[CAKeyframeAnimation animationWithKeyPath:@"position"];
    animation.path =path;
    animation.removedOnCompletion =NO;
    animation.fillMode =kCAFillModeForwards;
    animation.timingFunction =[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
    animation.autoreverses = NO;
    animation.duration =time;
    animation.repeatCount =repeatTimes;
    return animation;
}

-(CABasicAnimation *)rotation:(float)dur degree:(float)degree direction:(int)direction repeatCount:(int)repeatCount
{
    CATransform3D rotationTransform =CATransform3DMakeRotation(degree, 0, 0, direction);
    CABasicAnimation *animation =[CABasicAnimation animationWithKeyPath:@"transform"];
    animation.toValue =[NSValue valueWithCATransform3D:rotationTransform];
    animation.duration =dur;
    animation.autoreverses =NO;
    animation.cumulative =NO;
    animation.fillMode =kCAFillModeForwards;
    animation.repeatCount =repeatCount;
    animation.delegate =self;
    return animation;
}
