Iphone 模拟动画内存不足

我正在尝试基于一系列54幅图像模拟动画。我收到一条“程序接收信号：”0“。消息-内存不足

我正在尽力照顾他们，因为我似乎失败了。我在大约4-5秒内完成了所有54个步骤，然后应该会重复（几乎像一本翻页书）。由于图像中有闪亮的3D材质，因此使用核心动画无法轻松完成动画

或者，有没有更好的办法

代码如下：

-(void)addImage:(NSString*)imageName{
    if (self.images == nil){
        self.images = [[[NSMutableArray alloc] init] autorelease];
    }
    [self.images addObject:[UIImage imageNamed:imageName]];
}

// Returns a UIImageView that contains the next image to display
- (UIImageView *)nextImageView
{
    // get the image at the next index
    UIImage *image = [images objectAtIndex:pictureIndex];
    ++pictureIndex; // increment the index

    if(pictureIndex > images.count -1){
        pictureIndex = 0;
    }


    // create an image view for the image
    UIImageView *imageView = [[UIImageView alloc] initWithImage:image];

    // resize the image to fill the screen without distorting
    imageView.frame = rotator.frame;

    imageView.autoresizesSubviews = NO;
    [imageView setContentMode:UIViewContentModeCenter];


    // Makes the image move proportionally in any direction if the
    // bounds of the superview change when the iPhone is rotated.
    imageView.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin |
                                  UIViewAutoresizingFlexibleRightMargin |                          
                                  UIViewAutoresizingFlexibleTopMargin |                            
                                  UIViewAutoresizingFlexibleBottomMargin);

    return imageView;
}

- (void)timerFired:(NSTimer *)_timer{
    UIImageView *nextImageView = [self nextImageView];
    if(nextImageView){
        [self.view addSubview:nextImageView];
        nextImageView.alpha = 0.0;

        //NSLog(@"timerFired - image no: %i", pictureIndex);

        // begin animation block
        [UIView beginAnimations:nil context:nextImageView];
        [UIView setAnimationDuration:animationDuration]; // set the animation length
        [UIView setAnimationDelegate:self]; // set the animation delegate

        // call the given method when the animation ends
        [UIView setAnimationDidStopSelector:@selector(transitionFinished:finished:context:)];

        // make the next image appear with the chosen effect
        [nextImageView setAlpha:1.0]; // fade in the next image
        [currentImageView setAlpha:0.0]; // fade out the old image

        [UIView commitAnimations];
    } else {
        [timer invalidate];
        timer = nil;
    }

}

// called when the image transition animation finishes
- (void)transitionFinished:(NSString *)animationId finished:(BOOL)finished context:(void *)context
{
    [currentImageView removeFromSuperview]; // remove the old image
    [currentImageView release]; // release the memory for the old image
    currentImageView = context; // assign the new image
}

-(void)startRotator{
    self.rotator.animationImages = self.images;
    self.rotator.animationDuration = animationDuration;

    pictureIndex = 0; // reset the index

    currentImageView = [self nextImageView]; // load the first image
    [self.view addSubview:currentImageView]; // add the image to the view

    //[self.rotator startAnimating];
    NSLog(@"start Animating - Image Count: %i", self.images.count);

    timer = [NSTimer scheduledTimerWithTimeInterval:scheduledInterval 
                                             target:self
                                           selector:@selector(timerFired:) 
                                           userInfo:nil 
                                            repeats:YES];
}

您正在

nextImageView

中泄漏

imageView

。返回的实例应自动删除

你确定你的54幅图像适合memeory吗？

还要记住，大多数图像格式都未经压缩存储在iPhone的内存中，因此它们占用的内存可能比你意识到的要多。iOS可以将压缩后的PVRTC图像存储在内存中，但它们也有自己的折衷方案。它将在transitionFinished中发布。我能够把它们全部缩小，这似乎起到了作用。你能告诉我更多关于PVRTC的情况吗？
