保存AVAudioRecording路徑

我設法設置AVAudiorecorder進行錄製，但我想將錄製文件保存在文檔目錄中以稍後收聽。我嘗試這樣做：保存AVAudioRecording路徑

- (void) audioRecorderDidFinishRecording:(AVAudioRecorder *)avrecorder successfully:(BOOL)flag{ 

ButtonStopRecording.hidden = YES; 

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"audioFile.ext"]; // Where ext is the audio format extension you have recorded your sound 
[avrecorder.data writeToFile:filePath atomically:YES]; 

}

但在

avrecorder.data

錯誤我該如何解決這個問題？

現在您必須知道，如果您發佈有關錯誤的問題，則應在問題中包含完整的錯誤。 – rmaddy

嘗試訪問使用

avrecorder.url

文件假定您已經正確設置你的刻錄機，當你開始record

這樣的事情...

NSString *temnpVoiceFile = [NSString pathWithComponents:[NSArray arrayWithObjects:[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject], @"tempVoice.caf", nil]]; 

// We need to update the file generator 
NSURL *soundFileURL = [NSURL fileURLWithPath:temnpVoiceFile]; 

NSError *error = nil; 

// Instantiate an audio recorder. 
self.audioRecorder = [[[AVAudioRecorder alloc] initWithURL:soundFileURL settings:_recordSettings error:&error] autorelease]; 
NSAssert1(!error, @"error creating audio file = %@", error); 

BOOL fileSuccess = [_audioRecorder prepareToRecord]; 

NSAssert(fileSuccess, @"audio recorder could not be prepared."); 
[_audioRecorder record];

讓我知道你是否需要更多信息。

沒有AVAudioRecorder的數據屬性。當您初始化AVAudioRecorder時，您只需設置位置以保存錄制的音頻。設置錄像機時，只需將其設置到文檔目錄即可。

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"audioFile.ext"]; // Where ext is the audio format extension you have recorded your sound 
NSData *data=[NSData dataWithContentsOfURL:avrecorder.url]; 
    [data writeToFile:soundFilePath atomically:YES]; 
[data writeToFile:filePath atomically:YES];

我認爲這會對您有所幫助。
