SKAction playSoundFileNamed在500 mp3时失败了 [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（大约500个项目一个接一个）

所以我使用 SKAction playSoundFileNamed

在大约200声之后它崩溃了'无法加载资源 - 无法加载资源s234.mp3'。内存增加到70mb。

如何避免这种情况？

我尝试过：

1. 在每次迭代中重新创建声音

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




2. 在.m

   
   的开头创建一个变量
   

     SKAction * mySound; 
     

并在迭代中重复使用

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

2。
在开始时将所有声音加载到数组

  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。

如何清除此内存泄漏？

已编辑
我也试图关闭ARC并每次手动解除它。没有任何改变。

解决方案

这里的小小调将允许您使用常规的旧SKAction，但可以自定义代码中的播放。 / p>

https：// github .com / pepelkod / iOS- Examples / tree / master / 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组：@ [playAction，waitAction]]; 
返回groupActions; 
} 
返回playAction; 
  

}

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

So I use SKAction playSoundFileNamed

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

How to avoid this?

What I tried:

1. recreate sound in every iteration

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

2. create the one variable in the beggining of .m

   SKAction *mySound;
   

and reuse it in iterations

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

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]];
    }

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

How to clean this memory leaks?

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

解决方案

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/master/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;

}
