ios - 视频录制就像会说话的汤姆应用程序

Question

我正在开发一个像会说话的汤姆这样的应用程序。当我们触摸iPhone屏幕时，会产生一些带声音的狗动画。为此，我实现了除了iPhone屏幕视频录制之外的所有功能。我基于here实现了iPhone屏幕视频录制。 .它录制了没有声音的狗动画。我必须做什么才能在视频文件中包含音频？有可用的示例代码吗？

如果你使用cocos2D开发你的应用程序，示例代码here将会很有用!

Answer 1

在 AVFoundation 框架中使用 AVAudioRecorder。导入 AVFoundation 框架并符合 AVAudioRecorderDelegate创建 AVAudioRecorder 实例和 NSURL 实例**示例代码

录音:

    [audioSession setCategory:AVAudioSessionCategoryRecord error:nil]; // assign it to recording session
    [audioSession setActive:YES error:nil]; // activate it!
      NSMutableDictionary* recordSetting = [[NSMutableDictionary alloc] init];
       [recordSetting setValue: [NSNumber numberWithInt:kAudioFormatAppleIMA4]    forKey:AVFormatIDKey]; // assign this special hardware component as the function to record
    [recordSetting setValue:[NSNumber numberWithFloat:44100.0]
    forKey:AVSampleRateKey]; //44100 is the sample rate 
   [recordSetting setValue:[NSNumber numberWithInt: 2]
    forKey:AVNumberOfChannelsKey]; // same thing
   tmpFile = [NSURL fileURLWithPath:
      [NSTemporaryDirectory() stringByAppendingPathComponent:
    [NSString stringWithFormat: @"%.0f.%@",
     [NSDate timeIntervalSinceReferenceDate] * 1000.0,
      @"caf"]]]; // how we identify the audio written to the file to play later
      recorder = [[AVAudioRecorder alloc] initWithURL:tmpFile settings:recordSetting
    [recorder setDelegate:self];
   [recorder prepareToRecord];
   [recorder record];

播放:

    AVAudioSession * audioSession = [AVAudioSession sharedInstance];
   [audioSession setCategory:AVAudioSessionCategoryPlayback error:nil];
       [audioSession setActive:YES error:nil];
      AVAudioPlayer * player =
       [[AVAudioPlayer alloc] initWithContentsOfURL:tmpFile error:nil]; // takes recording data from tmpFile where we wrote the recording in
      [player prepareToPlay];
     [player play];

这只是一些示例代码......可以帮助您，但否则请阅读文档我不确定如何为嘴巴设置动画，或者是否想改变音调，但这只是录制的开始
