SKAction playSoundFileNamed 在 500 mp3 时失败 [英] SKAction playSoundFileNamed failed at 500 mp3

问题描述

在我的应用程序中，我需要使用很多不同的短mp3(一个一个大约500个项目)

In my application I need to use a lot of short different mp3s (about 500 items one by one)

所以我使用 SKAction playSoundFileNamed

大约 200 次声音后，它因加载资源失败 - 无法加载资源 s234.mp3"而崩溃.内存增加到 70mb.

After ~200 sounds it crashed with 'Failed to load resource - Resource s234.mp3 can not be loaded'. Memory rises to 70mb.

如何避免这种情况?

我尝试了什么:

1. 在每次迭代中重新创建声音

1. recreate sound in every iteration

SKAction *mySound=[SKAction playSoundFileNamed:aa waitForCompletion:YES];

在.m开头创建一个变量

create the one variable in the beggining of .m

SKAction *mySound;

并在迭代中重用它

    mySound=[SKAction playSoundFileNamed:aa waitForCompletion:YES];

2.在开始时将所有声音加载到数组中

2. load all sounds to array once at start

for (int j=0;j<500;j++){
        NSString *aa=[NSString stringWithFormat:@"s%d.mp3", j];
        [item.sounds addObject:[SKAction playSoundFileNamed:aa waitForCompletion:YES]];
    }

...但从未改变 - 它崩溃并且无法加载 mp3.

...but never changed - it crashes and can't load mp3.

如何清理这种内存泄漏?

已编辑我还尝试关闭 ARC 并每次手动解除分配.没有任何改变.

EDITED I also tried to turn off ARC and manually dealloc it every time. Nothing changed.

推荐答案

这里的这个小玩意将允许您使用常规的旧 SKAction，但可以在代码中自定义播放.

This little ditty right here will allow you to use a regular old SKAction but customize the playback in code.

https://github.com/pepelkod/iOS-Examples/tree/主/PlaySoundWithVolume

+(SKAction*)playSoundFileNamed:(NSString*)fileName atVolume:(CGFloat)volume waitForCompletion:(BOOL)wait{
// setup audio
NSString*   nameOnly = [fileName stringByDeletingPathExtension];
NSString*   extension = [fileName pathExtension];
NSURL *soundPath = [[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:nameOnly ofType:extension]];
AVAudioPlayer *player = [[AVAudioPlayer alloc]initWithContentsOfURL:soundPath error:NULL];
[player setVolume:volume];
[player prepareToPlay];

SKAction*   playAction = [SKAction runBlock:^{
    [player play];
}];
if(wait == YES){
    SKAction*   waitAction = [SKAction waitForDuration:player.duration];
    SKAction* groupActions = [SKAction group:@[playAction, waitAction]];
    return groupActions;
}
return playAction;

}
