我的应用程序中有许多动画(如 70 个、7 个视图控制器中的 10 个)具有相同类型的空隙和功能,当我在我的设备或模拟器中运行时,应用程序崩溃。
如何使用线程或调度改进这些动画,或者问题是内存?
如何做到这一点,在另一个问题和教程中,对动画使用相同的方法并且非常简单,代码是这样的,我对我的应用程序中需要的任何动画重复:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    [self CargarSonidos];
    [self getArrayEffectImagen1];
    self.imgImagen1.animationImages = self.arrayEffectImagen1;
    self.imgImagen1.animationDuration = 1.0f;
    [sonido play];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (void)getArrayEffectImagen1
{
    NSMutableArray *arrayEfecto = [[NSMutableArray alloc] init];

    for (int i=0; i<14; i++) {
        UIImage *imagen = [UIImage imageNamed:[NSString stringWithFormat:@"Imagen%d.png",i]];
        [arrayEfecto addObject:imagen];
    }

    self.arrayEffectImagen1 = [NSArray arrayWithArray:arrayEfecto];
}

-(void)CargarSonidos
{
    NSURL *Imagen1Url = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"PrimerSonido"ofType:@"MP3"]];

    NSError *error;
    Sonido = [[AVAudioPlayer alloc]initWithContentsOfURL:Imagen1Url error:&error];

    if (error)
    {
        NSLog(@"Error in audioPlayer: %@",[error localizedDescription]);
    }
    else
    {
        Sonido.delegate = self;
        [Sonido prepareToPlay];
    }
}

-(IBAction)Animacion1
{
    [Sonido play];
    [self.imgImagen1 setAnimationRepeatCount:1];
    [self.imgImagen1 startAnimating];
}

-(void)audioPlayerDidFinishPlaying:
(AVAudioPlayer *)player successfully:(BOOL)flag
{
}
-(void)audioPlayerDecodeErrorDidOccur:
(AVAudioPlayer *)player error:(NSError *)error
{
}
-(void)audioPlayerBeginInterruption:(AVAudioPlayer *)player
{
}
-(void)audioPlayerEndInterruption:(AVAudioPlayer *)player
{
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    [Sonido stop];
}

-(IBAction)TapOne:(UITapGestureRecognizer *)recognizer
{
    [self Animacion1];
}

我正在使用 Xcode 4.6 并且该应用程序适用于 iOS 5.0。我使用带有故事板和模态或推送segue的ARC,我确实尝试以一种简单的方式创建这个应用程序,所以如果你知道一些事情或帮助我,我该如何以更好的方式通过线程或调度来修复或改进这段代码?

并且是的,崩溃日志是:

这里有几个可能的问题:

  1. 一个问题是imageNamed会缓存图像。您可以考虑imageWithContentsOfFile改用。正如imageNamed文档所说:

    如果您有一个只显示一次的图像文件并希望确保它不会被添加到系统的缓存中,您应该改为使用imageWithContentsOfFile:. 这将使您的一次性图像远离系统图像缓存,从而潜在地改善您的应用程序的内存使用特性。

    因此,如果您将图像用于一次性(或不经常使用)动画,请考虑使用imageWithContentsOfFile而不是imageNamed.

  2. 动画完成后(可以通过检查isAnimating属性来检测,例如在 a 中CADisplayLink),您可以查看nilanimationImages属性UIImageView,这将释放对这些图像的强引用。

  3. 图像的大小适合UIImageView吗?如果您的图像大小(以像素为单位,而不是文件大小)超过了图像视图的大小,iOS 将优雅地调整视图中的图像大小(取决于您的contentMode),但它仍会将未压缩的图像存储在内存中(通常每个像素占用四个字节)。不要查看 PNG/JPG 文件的大小来考虑内存影响(因为这些是压缩文件格式,当您使用它们时在内存中未压缩)。查看底层证券的尺寸UIImage

    如果图像尺寸超过了图像视图所需的尺寸,您可能需要调整它们的大小。根据图像的大小,这可能会对内存消耗产生巨大影响。有许多图像大小调整算法(例如this)。
