IOS AVAudioPlayer的最大音量级别？ [英] IOS maximum volume level for AVAudioPlayer?

问题描述

我使用AVAudioPlayer播放.caf文件。我的问题是：它不够响亮我的目的。由于iPhone的振铃声响亮得多，我想知道如何归档这个音量。
我已经尝试操纵.caf文件，但没有取得真正的成功。有什么想法吗？

I use the AVAudioPlayer to play a .caf file. My problem is: it is not loud enough for my purpose. Since the ringer sound of the IPhone is much louder I was wondering how I can archive this volume. I already tried to manipulate the .caf file but with no real success. Any ideas?

到目前为止我使用的代码：

The code I use so far:

    AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: url error: nil];
self.appSoundPlayer = newPlayer;
[newPlayer release];
[appSoundPlayer prepareToPlay];
[appSoundPlayer setVolume: 0.8];
[appSoundPlayer setDelegate: self];
    [appSoundPlayer play];

编辑：

[appSoundPlayer setVolume: 1.0];

推荐答案

您可以随时将音量设置为实际最大值，例如：

You could always set the volume to actual maximum eg:

[appSoundPlayer setVolume: 1.0];

除此之外，您可能需要自己编辑文件。

Other than that, you probably will have to edit the file itself.
