Question

当我希望用户分享他的语音备忘录时，我正在编写Titanium iPhone应用程序。

有两种选择：（1）记录 - ＆gt;保存 - ＆gt;分享（2）浏览语音备忘录 - ＆gt;共享

我在这两方面都面临着问题。在（1）中，我设法录制了一个音频并进行播放。但我很困惑如何将这个录制的声音对象转换为文件对象，以便我可以共享该文件。在（2）中，我无法找到以编程方式访问语音备忘录记录的方法。

任何帮助???

Answer 1

不要回答什么是语音备忘录，但我可以帮助你解决第一个问题：

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
    NSError *err = nil;
    [audioSession setCategory :AVAudioSessionCategoryPlayAndRecord error:&err];
    if(err){
        NSLog(@"audioSession: %@ %d %@", [err domain], [err code], [[err userInfo] description]);
        return;
    }
    [audioSession setActive:YES error:&err];
    err = nil;
    if(err){
        NSLog(@"audioSession: %@ %d %@", [err domain], [err code], [[err userInfo] description]);
        return;
    }

    recordSetting = [[NSMutableDictionary alloc] init];

    // We can use kAudioFormatAppleIMA4 (4:1 compression) or kAudioFormatLinearPCM for nocompression
    [recordSetting setValue :[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey];

    // We can use 44100, 32000, 24000, 16000 or 12000 depending on sound quality
    [recordSetting setValue:[NSNumber numberWithFloat:16000.0] forKey:AVSampleRateKey];

    // We can use 2(if using additional h/w) or 1 (iPhone only has one microphone)
    [recordSetting setValue:[NSNumber numberWithInt: 1] forKey:AVNumberOfChannelsKey];


    // Create a new dated file

    recorderFilePath = [[NSString stringWithFormat:@"%@/Parking.caf", DOCUMENTS_FOLDER] retain];

    NSLog(@"recorderFilePath: %@",recorderFilePath);

    NSURL *url = [NSURL fileURLWithPath:recorderFilePath];

    err = nil;

    NSData *audioData = [NSData dataWithContentsOfFile:[url path] options: 0 error:&err];
    if(audioData)
    {
        NSFileManager *fm = [NSFileManager defaultManager];
        [fm removeItemAtPath:[url path] error:&err];
    }

    err = nil;
    recorder = [[ AVAudioRecorder alloc] initWithURL:url settings:recordSetting error:&err];
    if(!recorder){
        NSLog(@"recorder: %@ %d %@", [err domain], [err code], [[err userInfo] description]);
        UIAlertView *alert =
        [[UIAlertView alloc] initWithTitle: @"Warning"
                                   message: [err localizedDescription]
                                  delegate: nil
                         cancelButtonTitle:@"OK"
                         otherButtonTitles:nil];
        [alert show];
        [alert release];
        return;
    }

    //prepare to record
    [recorder setDelegate:self];
    [recorder prepareToRecord];
    recorder.meteringEnabled = YES;

    BOOL audioHWAvailable = audioSession.inputIsAvailable;
    if (! audioHWAvailable) {
        UIAlertView *cantRecordAlert =
        [[UIAlertView alloc] initWithTitle: @"Warning"
                                   message: @"Audio input hardware not available"
                                  delegate: nil
                         cancelButtonTitle:@"OK"
                         otherButtonTitles:nil];
        [cantRecordAlert show];
        [cantRecordAlert release]; 
        return;
    }

    // start recording
    [recorder recordForDuration:(NSTimeInterval) 30];

Answer 2

问题1的解决方案：

您可以直接创建文件对象并在其上写下您记录的数据，

// Save the data to file. Overwrite if fill
var file = Titanium.Filesystem.getFile( 'Your path', 'yourfile.wav' );

// Write the data.
file.write( recordData );

问题2的解决方案： 我不确定Titanium中是否有Voice Memos。

Answer 3

经过大量研究后，我设法保存了声音文件。问题1的解决方案：

var file = var file = Titanium.Filesystem.getFile( 'thePath', 'newRecording.wav' );

// Write the data.

file.write( sound.toBlob() );

仍在努力解决第二个问题。任何帮助???
