How do I programmatically play an MP3 on an iPhone?
提问by AngryHacker
I'd like to include an MP3 with my app and play it on demand. Unfortunately I am not sure how to get started. I keep reading about .caf files, but I am not sure what those are.
我想在我的应用程序中包含 MP3 并按需播放。不幸的是，我不知道如何开始。我一直在阅读 .caf 文件，但我不确定那些是什么。
I am looking for a step by step, if possible.
如果可能的话，我正在寻找一个循序渐进的方法。

You could also try the AVAudioPlayerutility Framework.
您也可以尝试使用AVAudioPlayer实用程序框架。

Here is what I am doing to play mp3 in xCode 4.2:
这是我在 xCode 4.2 中播放 mp3 所做的工作：
1) Import AVFoundation.frameworkframework into your project
1) 将AVFoundation.framework框架导入到您的项目中
2) Adding: #import "AVFoundation/AVAudioPlayer.h"into your project ViewController.hfile:
2）添加：#import "AVFoundation/AVAudioPlayer.h"到您的项目ViewController.h文件中：
#import <UIKit/UIKit.h>
#import "AVFoundation/AVAudioPlayer.h"
@interface ViewController : UIViewController
@end
3) Drag and drop your mp3 file yoursoundfile.mp3into your root project explorer
3) 将您的 mp3 文件拖放yoursoundfile.mp3到您的根项目资源管理器中
4) Modify -(void)viewDidLoadin ViewController.m:
4）修改-(void)viewDidLoad中ViewController.m：
- (void)viewDidLoad{
[super viewDidLoad];
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:@"yoursoundfile"
ofType:@"mp3"]];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:url
error:nil];
[audioPlayer play];
}
As soon as you start your program, it will play the sound. You can customize to fit your app by changing volume, or when to play, stop...
只要您启动程序，它就会播放声音。您可以通过更改音量或播放时间、停止时间来自定义以适合您的应用程序...

Use afconvert in Terminal to convert your MP3 to a .caf. man afconvert will tell you more.
在终端中使用 afconvert 将您的 MP3 转换为 .caf。man afconvert 会告诉你更多。
Then
然后
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource: name ofType: @"caf"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath];
AVAudioPlayer *player = [super initWithContentsOfURL: fileURL error: nil];
[fileURL release];
[player play];
