使用代码过滤器:
imgAnimation=[[UIImageView alloc]initWithFrame:frame];
imgAnimation.animationImages=_arrimg;
//animationImages=animationImages;
imgAnimation.contentMode=UIViewContentModeScaleAspectFit;
imgAnimation.animationDuration = 2.0f;
imgAnimation.animationRepeatCount = 0;
[imgAnimation startAnimating];
[self.view addSubview:imgAnimation];
动画实现的很好,还要实现 sepia, grey scale 效果。不知道怎么实现?
