在ios中播放mp3文件失败[重复]答案

【问题标题】：mp3 file playing failed in ios [duplicate]在ios中播放mp3文件失败[重复]
【发布时间】：2012-08-07 11:24:39
【问题描述】：

可能重复：
Sound stop playing

我对 iPhone 应用程序开发非常陌生。我想在我的应用程序中播放一个 .mp3 文件。这是我尝试执行的代码 sn-p。“dd.mp3”是支持文件下的文件。但它不起作用。我做错了什么吗？

NSError *error=nil;
NSURL *audioURL =[[NSBundle mainBundle] URLForResource:@"dd" withExtension:@"mp3"];
AVAudioPlayer *avPlayerObject = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:&error];

if(avPlayerObject)
{
 [avPlayerObject play];
}

当我运行此代码时，我得到以下错误输出。

@Intrus：我认为“NSSound”适用于 mac 开发。不适用于 iPhone

【解决方案1】：

我发布了一条评论，其中包含指向与您类似的另一个堆栈溢出问题的链接，但这里有一个链接可以逐步引导您：

在您的 IOS 应用中播放音频：

【讨论】：

感谢 Intrus :) 问题已解决

【解决方案2】：

NSString *path = [[NSBundle mainBundle] pathForResource:@"sound" ofType:@"caf"];
self.audioPlayer =[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:path] error:nil];
[self.audioPlayer setDelegate:self];
[self.audioPlayer prepareToPlay];
[self.audioPlayer play];

caf 是音频文件格式。

另外，将 AVFoundation.framework 添加到您的项目中。

添加到“.h”文件中。
