用UIImageView实现动画时内存管理问题

Question

我有一组序列帧，想用UIImageView来做成动画。我的代码如下

UIImageView* campFireView = [[UIImageView alloc] initWithFrame:self.view.frame];
        
        NSMutableArray *moviesSourceArray = [NSMutableArray arrayWithCapacity:200];
        int i = 1;
        
        for (i = 1; i <= 100; i++) {
            NSString *imageName;
            imageName = [NSString stringWithFormat:@"image%i.png",i];
            [moviesSourceArray addObject:[UIImage imageNamed:imageName]];
        }
                
        campFireView.animationImages = moviesSourceArray;
        
        campFireView.animationDuration = 1.75;
        
        campFireView.animationRepeatCount = 0;
        
        [campFireView startAnimating];
        
        [controller.view addSubview:campFireView];
        [campFireView release];

我的序列帧图片比较多，一共40M的样子，200张。如果全部图片都加入进来播放的话就会崩溃，减少到100张能正常运行。有没有其他比较好的办法或者优化方案来实现播放完整动画而又不会出现这样内存占用太多崩溃的情况呢？

Answer 1

果断存成mov，用个视频view播放啊

别说40M。10M图片在iOS6上让你崩不是啥难事。

Answer 2

动态加载图片啊，不要把图片一下全部加在进去。下面的代码可供参考。

imgV=[[UIImageView alloc]initWithFrame:CGRectMake(40, 40, 128, 128)];
[self.window addSubview:imgV];
[self performSelectorInBackground:@selector(playAnim)withObject:nil];

[imgV release];
-(void)playAnim{
for (int i=0;i<101;){
usleep(100000);
UIImage *image=[[UIImage alloc]initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"%d",i+1 ] ofType:@"tiff"]];
[self performSelectorOnMainThread:@selector(changeImage:) withObject:image waitUntilDone:YES];
i++;

}
} 
-(void)changeImage:(UIImage*)image{
imgV.image=image; 
}
