ios - Swift: play the audio recorded -

-

i tried record , find answer here: recording audio in swift

i make work. know how play recorded audio. recording have general var audiorecorder, , defined url path. tried audiorecorder.play() not work.

i suppose problem comes form fact global var audiorecorder instance of avaudiorecorder , play should instance of avaudioplayer?, how 2 things related?

i not want copy paste peace of code understand. why simplify code here. please explain why not work in specific code , how solve it.

(i have done lot of tutorials related. problem there code lost. question here understand how specific part works)

import avfoundation var audiorecorder:avaudiorecorder! @ibaction func record(sender: anyobject) {            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 string)     println(url)      audiorecorder = avaudiorecorder(url:url, settings: nil, error: nil)     audiorecorder.record() }  @ibaction func play(sender: anyobject) {    // gives error 'avaudiorecorder' not have member named 'play'    // audiorecorder.play()  }

here complete working code record audio store file play it:

import uikit import avfoundation  class viewcontroller: uiviewcontroller, avaudioplayerdelegate, avaudiorecorderdelegate {      @iboutlet weak var recordbutton: uibutton!     @iboutlet weak var stopbutton: uibutton!     @iboutlet weak var playbutton: uibutton!      var audioplayer : avaudioplayer?     var audiorecorder : avaudiorecorder?       override func viewdidload() {         super.viewdidload()         playbutton.enabled = false         stopbutton.enabled = false          // getting url path audio         let dirpath = nssearchpathfordirectoriesindomains(.documentdirectory, .userdomainmask, true)         let docdir = dirpath[0] as! string         let soundfilepath = docdir.stringbyappendingpathcomponent("sound.caf")         let soundfileurl = nsurl(fileurlwithpath: soundfilepath)         println(soundfilepath)          //setting recorder         let recordsettings = [avencoderaudioqualitykey: avaudioquality.min.rawvalue,             avencoderbitratekey: 16,             avnumberofchannelskey : 2,             avsampleratekey: 44100.0]         var error : nserror?         let audiosession = avaudiosession.sharedinstance()         audiosession.setcategory(avaudiosessioncategoryplayandrecord, error: &error)         if let err = error{             println("audiosession error: \(err.localizeddescription)")         }         audiorecorder = avaudiorecorder(url: soundfileurl, settings: recordsettings [nsobject : anyobject], error: &error)          if let err = error{             println("audiosession error: \(err.localizeddescription)")         }else{             audiorecorder?.preparetorecord()         }     }     //record audio     @ibaction func recordaudio(sender: anyobject) {          if audiorecorder?.recording == false{             playbutton.enabled = false             stopbutton.enabled = true             audiorecorder?.record()         }     }     //stop recording audio     @ibaction func stopaudio(sender: anyobject) {          stopbutton.enabled = false         playbutton.enabled = true         recordbutton.enabled = true          if audiorecorder?.recording == true{             audiorecorder?.stop()         }else{             audioplayer?.stop()         }     }     //play recorded audio     @ibaction func playaudio(sender: anyobject) {          if audiorecorder?.recording == false{             stopbutton.enabled = true             recordbutton.enabled = false              var error : nserror?              audioplayer = avaudioplayer(contentsofurl: audiorecorder?.url, error: &error)              audioplayer?.delegate = self              if let err = error{                 println("audioplayer error: \(err.localizeddescription)")             }else{                 audioplayer?.play()             }         }     }      func audioplayerdidfinishplaying(player: avaudioplayer!, flag: bool) {         recordbutton.enabled = true         stopbutton.enabled = false     }      func audioplayerdecodeerrordidoccur(player: avaudioplayer!, error: nserror!) {         println("audio play decode error")     }      func audiorecorderdidfinishrecording(recorder: avaudiorecorder!, flag: bool) {     }      func audiorecorderencodeerrordidoccur(recorder: avaudiorecorder!, error: nserror!) {         println("audio record encode error")     } }

check this sample project more info.

in code audiorecorder used record audio , audioplayer used play audio. thats why audiorecorder doesn't have property play()

so can not use audiorecorder.play().
