I am trying to play a song based on the instrument the user selects. Here is my code:
@IBAction func play(sender: AnyObject) {
if isPlaying == false {
player.play()
isPlaying = true
}
}
@IBAction func stop(sender: AnyObject) {
if isPlaying == true {
player.stop()
isPlaying = false
}
}
@IBAction func pause(sender: AnyObject) {
if isPlaying == true {
isPlaying = false
player.pause()
}
}
var player = AVAudioPlayer()
var audioPath = NSBundle.mainBundle().pathForResource("Iditarod Bass", ofType: "m4a")
var isPlaying = Bool()
@IBOutlet var instrumentSelect: UISegmentedControl!
@IBAction func didChangeInstrument(sender: AnyObject) {
if isPlaying == false {
if instrumentSelect.selectedSegmentIndex == 0 {
audioPath = NSBundle.mainBundle().pathForResource("Iditarod Bass", ofType: "m4a")
do {
try player = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: audioPath!))
} catch {
}
} else if instrumentSelect.selectedSegmentIndex == 1 {
audioPath = NSBundle.mainBundle().pathForResource("Iditarod Cello", ofType: "m4a")
do {
try player = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: audioPath!))
} catch {
}
} else if instrumentSelect.selectedSegmentIndex == 2 {
audioPath = NSBundle.mainBundle().pathForResource("Iditarod Viola", ofType: "m4a")
do {
try player = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: audioPath!))
} catch {
}
} else if instrumentSelect.selectedSegmentIndex == 3 {
audioPath = NSBundle.mainBundle().pathForResource("Iditarod Violin 1", ofType: "m4a")
do {
try player = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: audioPath!))
} catch {
}
} else if instrumentSelect.selectedSegmentIndex == 4 {
audioPath = NSBundle.mainBundle().pathForResource("Iditarod Violin 2", ofType: "m4a")
do {
try player = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: audioPath!))
} catch {
}
}
}
}
All of them work fine except for the instrumentSelect.selectedSegmentIndex == 1. I don't know why. I get an EXC_BAD_INSTRUCTION that says fatal error: unexpectedly found nil while unwrapping an Optional value. The file is working fine, and I have cleaned the project numerous times. I have typed everything correctly. Why is that one not working? I am very confused about this, and I appreciate your help.
