我已经在我的应用程序中实现了音频录制,但我需要知道如何将音频录制文件保存在文档目录中,并在其他类中检索用于播放音频的相同文件。如何将iPhone音频文件保存在文档目录中

这里是源代码。

-(void)startPushed 
{ 
     NSMutableDictionary *rs = [[NSMutableDictionary alloc] init]; 
     [rs setValue:[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey]; 
     [rs setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey]; 
     [rs setValue:[NSNumber numberWithInt:2] forKey:AVNumberOfChannelsKey]; 
     recordedTmpFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"%.0f.%@", [NSDate timeIntervalSinceReferenceDate] * 1000.0, @"caf"]]]; 

     recorder = [[AVAudioRecorder alloc] initWithURL:recordedTmpFile settings:rs error:&error]; 
     [recorder setDelegate:self]; 
     [recorder prepareToRecord]; 
     [recorder record]; 


     NSArray *docPath = NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES); 
     NSString *docDir = [docPath objectAtIndex:0]; 
     NSString *fullPath = [docDir stringByAppendingPathComponent:[NSString stringWithFormat:@"%@", recordedTmpFile]]; 
     NSLog(@"%@", fullPath); 
} 

-(void)playbackPushed 
    { 
    AVAudioPlayer *avPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:recordedTmpFile error:&error]; 
     NSLog(@"Play Path:%@", recordedTmpFile); 
     [avPlayer prepareToPlay]; 
     [avPlayer play]; 
    } 

请告诉我如何读取和写入文件目录 音频文件(格式的.caf),也给了其他类音频播放的信息。

在此先感谢

访问文档目录在iOS中使用此代码

-(NSURL *)documentDirectory{ 
return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]; 

}

和使用的NSFileManager到文件复制到该路径。
