Currently I can add the current playing song on the iPhone to my app, but I am trying to play a song from Parse based on the song title on the app, but I am getting a nil error. Why?
func playit(sender: UIButton!){
if let nowPlaying = musicPlayer.nowPlayingItem{
let title = nowPlaying[MPMediaItemPropertyTitle] as? String
let artist = nowPlaying[MPMediaItemPropertyTitle] as? String
println(title! + artist!)
let query = PFQuery(className: "Songs")
query.whereKey("SongName", equalTo: title!)
query.findObjectsInBackgroundWithBlock {
(objects: [AnyObject]?, error: NSError?) -> Void in
if error == nil {
// The find succeeded.
println("Successfully retrieved \(objects!.count) song(s).")
// Do something with the found objects
if let objects = objects as? [PFObject] {
for object in objects {
println(object.objectId)
let objects: PFObject = object as PFObject
let parseAudio: PFFile = objects.valueForKey("Songs") as! PFFile
let audioPath: String = parseAudio.url!
let urlParse: NSURL = NSURL(string: audioPath)!
player = AVPlayer(URL: urlParse)
println(player)
player.play()
}
}
} else {
// Log details of the failure
println("Error: \(error!) \(error!.userInfo!)")
}
}
}
}
Without knowing what the exact error is I can only say that your issues most likely resides in this block:
let objects: PFObject = object as PFObject
let parseAudio: PFFile = objects.valueForKey("Songs") as! PFFile
let audioPath: String = parseAudio.url!
let urlParse: NSURL = NSURL(string: audioPath)!
Converting parseAudio
to a string for your NSURL
isn't getting the content of the file for your media player. Try something like this:
let parseAudio: PFFile = objects.valueForKey("Songs") as? PFFile
parseAudio?.getDataInBackgroundWithBlock({ (data, error) -> Void in
if error == nil {
// do what you need to with the music file which is contained in `data`
let fullParseAudioFile = data
} else if error != nil {
println(error!.localizedDescription)
}
})
I haven't worked with the media player so I don't know what format you'll have to cast data to but you would now have the usable file instead of just a string representing the name of the file.
