有谁知道我在哪里可以找到有关如何在Swift应用程序中录制音频的信息？我一直在看一些音频播放示例，但是在实现音频记录方面似乎找不到任何东西。谢谢
这是代码。您可以轻松地进行记录。将此代码写在上。IBAction它将Documents按名称保存记录recordTest.caf
//declare instance variable
var audioRecorder:AVAudioRecorder!
func record(){
var audioSession:AVAudioSession = AVAudioSession.sharedInstance()
audioSession.setCategory(AVAudioSessionCategoryPlayAndRecord, error: nil)
audioSession.setActive(true, error: nil)
var documents: AnyObject = NSSearchPathForDirectoriesInDomains( NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)[0]
var str = documents.stringByAppendingPathComponent("recordTest.caf")
var url = NSURL.fileURLWithPath(str as String)
var recordSettings = [AVFormatIDKey:kAudioFormatAppleIMA4,
AVSampleRateKey:44100.0,
AVNumberOfChannelsKey:2,AVEncoderBitRateKey:12800,
AVLinearPCMBitDepthKey:16,
AVEncoderAudioQualityKey:AVAudioQuality.Max.rawValue]
println("url : \(url)")
var error: NSError?
audioRecorder = AVAudioRecorder(URL:url, settings: recordSettings, error: &error)
if let e = error {
println(e.localizedDescription)
} else {
audioRecorder.record()
}
}
