I have built an app that records an audio clip, and saves it to a file called xxx.m4a
.
Once the recording is made, I can find this xxx.m4a
file on my system and play it back - and it plays back fine. The problem isn't recording this audio track.
My problem is playing this audio track back from within the app.
// to demonstrate how I am building the recordedFileURL
let currentFileName = "xxx.m4a"
let dirPaths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
let docsDir: AnyObject = dirPaths[0]
let recordedFilePath = docsDir.stringByAppendingPathComponent(currentFileName)
var recordedFileURL = NSURL(fileURLWithPath: recordedFilePath)
// quick check for my own sanity
var checkIfExists = NSFileManager.defaultManager()
if checkIfExists.fileExistsAtPath(recordedFilePath){
println("audio file exists!")
}else{
println("audio file does not exist")
}
// play the recorded audio
var error: NSError?
let player = AVAudioPlayer(contentOfURL: recordedFileURL!, error: &error)
if player == nil {
println("error creating avaudioplayer")
if let e = error {
println(e.localizedDescription)
}
}
println("about to play")
player.delegate = self
player.prepareToPlay()
player.volume = 1.0
player.play()
println("told to play")
// -------
// further on in this class I have the following delegate methods:
func audioPlayerDidFinishPlaying(player: AVAudioPlayer!, successfully flag: Bool){
println("finished playing (successfully? \(flag))")
}
func audioPlayerDecodeErrorDidOccur(player: AVAudioPlayer!, error: NSError!){
println("audioPlayerDecodeErrorDidOccur: \(error.localizedDescription)")
}
My console output when I run this code is like this:
audio file exists!
about to play
told to play
I dont get anything logged into the console from either audioPlayerDidFinishPlaying
or audioPlayerDecodeErrorDidOccur
.
Can someone explain to me why I my audio clip isnt playing?
Many thanks.
