我有 5 个数组，用于加载和播放 5 组图像以形成 5 个不同的动画。

我有大量的内存问题。高达 500MB。当我在取景器中检查它们的大小时，这些图像在应用程序之外的总大小只有 15mb 左右。

我在我的应用程序运行时运行了记忆工具；

![5 个数组加载后的内存状态。][1]

此图显示了加载五个数组后的内存。在阵列运行后保留图像似乎很明显？或者至少我认为这是问题所在。

这是我用于每个数组的代码；

//Play Button 1 Animation

NSMutableArray *play1Frames = [[NSMutableArray alloc] initWithObjects:
               [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"play_button0000"] ofType:@"png"]],

               nil];
play1Image.animationImages = play1Frames;
play1Image.animationDuration = 3;
play1Image.animationRepeatCount = 1;
play1Frames = nil;

我想用这段代码做动画，我试过这段代码；

UIImage* animatedImage = [UIImage animatedImageNamed:@"Anim" duration:20];

但它并没有给我想要的功能，即使使用这段代码，内存问题仍然存在^

有谁知道问题可能是什么，或者如果我已经正确识别了问题，有人可以帮我解决它吗？

谢谢你。

我认为您应该尝试以下操作：将图像复制到包中，如下所示：

NSMutableArray *images=[[NSMutableArray   
alloc]initwithobjects:@"play_button0000.png",@"xxx.png",,,nil];

并编写您的动画代码。问题似乎是您将图像添加到数组的位置。

试一试。

试试这个，它工作正常，也没有任何内存问题：

// Load images
NSArray *imageNames = @[@"play_button0000.png", @"play_button0001.png", @"play_button0002.png", @"play_button0003.png",@"play_button0004.png", @"play_button0005.png", @"play_button0006.png", @"play_button0007.png",@"play_button0008.png", @"play_button0009.png", @"play_button0010.png", @"play_button0011.png",@"play_button0012.png", @"play_button0013.png", @"play_button0014.png",
                        @"play_button0015.png",@"play_button0016.png", @"play_button0017.png", @"play_button0018.png", @"play_button0019.png",@"play_button0020.png", @"play_button0021.png", @"play_button0022.png", @"play_button0023.png",@"play_button0024.png",
                        @"play_button0025.png"];
NSMutableArray *images = [[NSMutableArray alloc] init];
for (int i = 0; i < imageNames.count; i++) {
    [images addObject:[UIImage imageNamed:[imageNames objectAtIndex:i]]];

}
 // Normal Animation
animationImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320,480)];
animationImageView.animationImages = images;
animationImageView.animationRepeatCount=1;
animationImageView.animationDuration = 3;
[self.view addSubview:animationImageView];
[self.view sendSubviewToBack:animationImageView];

也许它会帮助你。
