我想用AVAudioPlayer读取mp3文件
#import <AVFoundation/AVFoundation.h>
AVAudioPlayer *player;
@property(retain,nonatomic) AVAudioPlayer *player;
@synthesize player
-(IBAction) lirepiste
{
NSString *file =@"http://media.islamway.net/lessons/othymeen/40nowaweyya/1.mp3";
player = [[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL URLWithString:file,error:nil];
[player play];
}
没有错误没有崩溃但也没有阅读

使您的标头文件看起来像这样
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
@interface FirstViewController : UIViewController <AVAudioPlayerDelegate> {
IBOutlet UIScrollView *LLScrollView;
AVAudioPlayer *data;
}
- (IBAction) playSound;
@end
并使实现看起来像这样
#import "FirstViewController.h"
@implementation FirstViewController
- (IBAction) playSound {
NSString *name = [[NSString alloc] initWithFormat:@"SoundName"];
NSString *source = [[NSBundle mainBundle] pathForResource:name ofType:@"mp3"];
if (data) {
[data stop];
[data release];
data = nil;
}
data=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath: source] error:NULL];
data.delegate = self;
[data play];
}
//everything else...
@end
如果你的声音文件名为“example.mp3”,那么在initWithFormat中只输入“example”和文件名。
此代码完美无瑕。祝你好运。

我按照你的推荐做了,但有两个错误: 架构i386的未定义符号: “_ OBJC_CLASS _ $ _ AVAudioPlayer”,引自: ViewController.o中的objc-class-ref ld:找不到架构i386的符号 clang:错误:链接器命令失败,退出代码为1(使用-v查看调用)
它出了什么问题?
