关于录音反正都是调用系统的东西，没啥好说的，直接上流程
var recorder:AVAudioRecorder? //录音器
var recorderSeetingsDic:[String : Any]! //录音器设置参数数组
var volumeTimer:Timer! //定时器线程，循环监测录音的音量大小
var aacPath:String! //录音存储路径
let docDir = NSSearchPathForDirectoriesInDomains(.documentDirectory,
.userDomainMask, true)[0]//获取手机根目录
var musicPlayer = AVAudioPlayer()//播放器
//初始化录音器
let session:AVAudioSession = AVAudioSession.sharedInstance()
//设置录音类型
try! session.setCategory(AVAudioSessionCategoryPlayAndRecord)
//初始化字典并添加设置参数
recorderSeetingsDic =
[
AVFormatIDKey: NSNumber(value: kAudioFormatMPEG4AAC),
AVNumberOfChannelsKey: 2, //录音的声道数，立体声为双声道
AVEncoderAudioQualityKey : AVAudioQuality.max.rawValue,
AVEncoderBitRateKey : 320000,
AVSampleRateKey : 44100.0 //录音器每秒采集的录音样本数
]
判断路径文件夹是否存在
recordPath = docDir + "/sound"
let fileManager = FileManager.default
// let exist = fileManager.fileExists(atPath: recordPath)�
let exist = fileManager.fileExists(atPath: recordPath)
if exist == false {
try! fileManager.createDirectory(atPath: recordPath,withIntermediateDirectories: true, attributes: nil)
// try! fileManager
}
let currentDate = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyyMMddHHmmss"
let myStr = dateFormatter.string(from: currentDate)
aacPath = recordPath + "/\(myStr).aac"
print(aacPath)
recorder = try! AVAudioRecorder(url: URL(string: aacPath)!,settings: recorderSeetingsDic!)
if recorder != nil {
//开启仪表计数功能
recorder!.isMeteringEnabled = true
//准备录音
recorder!.prepareToRecord()
//开始录音
recorder!.record()
}
//停止录音
recorder?.stop()
//录音器释放
recorder = nil
//暂停定时器
volumeTimer.invalidate()
volumeTimer = nil
开始播放
func startPlay() {
if (userDefult.value(forKey: "mySelectBtn") == nil) {
print(myIndex)
userDefult.setValue(myIndex.row, forKey: "mySelectBtn")
playSound()
}else{
linkRow = userDefult.value(forKey: "mySelectBtn") as! Int
if linkRow != myIndex.row {
let myindex :IndexPath = IndexPath(row: linkRow, section: 0)
userDefult.setValue(myIndex.row, forKey: "mySelectBtn")
DispatchQueue.main.async {
let mycell = self.recordTable.cellForRow(at: myindex) as! RecordTableViewCell
mycell.playBtn.isSelected = false
}
}
playSound()
}
}
func playSound(){
let sound = recordPath + "/\(titleArr[myIndex.row])"
// 播放
print(sound)
player = try! AVAudioPlayer(contentsOf: URL(string: sound)!)
player?.delegate = self
if player == nil {
print("播放失败")
}else{
player?.volume = 1.0
player?.prepareToPlay()
player?.play()
}
}
暂停播放
func stopPlay(){
if player == nil {
print("停止失败")
}else{
player?.currentTime = 0
player?.stop()
}
}
//播放完成监听
func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer, successfully flag: Bool) {
print("owari")
let cell = self.recordTable.cellForRow(at: myIndex) as! RecordTableViewCell
cell.playBtn.isSelected = false
}
录音的使用大致就是这样，只是还有小部分代码没有放上来，不过基本的流程就是这样的，等我时间充裕点再把录音单独从项目里面拿出来。
