问题描述

是否有可能实现动画使用CAAnimation图像序列？我不想使用的UIImageView ...

我需要类似的UIImageView的东西在这里我们可以设置imageView.animationImages并呼吁startAnimation ......但使用CAAnimation

解决方案

  CAKeyframeAnimation * animationSequence = [CAKeyframeAnimation animationWithKeyPath：@内容];
animationSequence.calculationMode = kCAAnimationLinear;
animationSequence.autoreverses = YES;
animationSequence.duration = kDefaultAnimationDuration;
animationSequence.repeatCount = HUGE_VALF;NSMutableArray里* animationSequenceArray = [[NSMutableArray里的alloc]初始化];
对于（*的UIImage在self.animationImages图片）
{
    [animationSequenceArray ADDOBJECT：（ID）image.CGImage]
}
animationSequence.values = animationSequenceArray;
[animationSequenceArray发布]
[self.layer addAnimation：animationSequence forKey：@内容];

Is it possible to implement animating sequence of images using CAAnimation? And i dont want to use UIImageView...

I need Something similar to UIImageView where we can set imageView.animationImages and calling startAnimation... but using CAAnimation

解决方案

CAKeyframeAnimation *animationSequence = [CAKeyframeAnimation animationWithKeyPath: @"contents"];
animationSequence.calculationMode = kCAAnimationLinear;
animationSequence.autoreverses = YES;
animationSequence.duration = kDefaultAnimationDuration;
animationSequence.repeatCount = HUGE_VALF;

NSMutableArray *animationSequenceArray = [[NSMutableArray alloc] init];
for (UIImage *image in self.animationImages) 
{
    [animationSequenceArray addObject:(id)image.CGImage];
}
animationSequence.values = animationSequenceArray;
[animationSequenceArray release];
[self.layer addAnimation:animationSequence forKey:@"contents"];
