ios - 用于动画的数组不释放图像。内存压力

标签 ios arrays memory instruments pressure

我有 5 个数组，用于加载和播放 5 组图像以形成 5 种不同的动画。

我有大量内存问题。高达 500mb。当我在 finder 中检查图像大小时，这些图像在应用程序之外的总大小只有大约 15mb。

我在我的应用程序运行时运行了内存工具；

![5个数组加载完成后的MEMORY状态。][1]

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

这是我为每个数组使用的代码；

//Play Button 1 Animation

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

               [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"play_button0023"] ofType:@"png"]],
               [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"play_button0024"] ofType:@"png"]],
               [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"play_button0025"] 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 ^

有没有人知道问题可能是什么，或者如果我正确地确定了问题，谁能帮我解决这个问题？

谢谢。

最佳答案

试试这个，它工作正常，也没有出现任何内存问题:

// 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];

也许它会对你有所帮助。
