ios - AVAudioPlayer playing overtime viewcont. loads [Swift] -

-

in mainmenuviewcontroller in viewdidload, tell play background song. problem is, when user goes view , goes main menu, starts playing song again, , 2 copies overlap. tried put in viewdidload didn't work

if themeplayer.playing == false {  themeplayer.preparetoplay()  themeplayer.play()  }

it kind of ignores if condition , plays anyways. how can fix this?

-viewdidload run when view loaded. since player still playing song when navigate away mainmenuviewcontroller indicates view controller never being deallocated. try putting if condition in -viewdidappear or -viewwillappear method.

override func viewwillappear(animated: bool) {     super.viewwillappear(animated);      if themeplayer == nil {         // either it's first time view loaded, or themeplayer deallocated         let soundurl = nsbundle.mainbundle().urlforresource("pres song", withextension: "mp3")          themeplayer = avaudioplayer(contentsofurl: soundurl, error: nil)          themeplayer.numberofloops = -1          themeplayer.volume = 0.1         themeplayer.preparetoplay()         themeplayer.play()     }      if themeplayer.playing == false {             themeplayer.preparetoplay()             themeplayer.play()         } }

if in doubt in future on if being called, use breakpoints , step through code.
