Xcode7.0.1问题,无法构建

import UIKit
import AVFoundation

class ViewController: UIViewController {

var APlayer:AVAudioPlayer!

@IBAction func PlayBtnClicked(sender: AnyObject) {
    APlayer.play()
}
@IBAction func PauseBtnClicked(sender: AnyObject) {
    APlayer.pause()
}
@IBAction func StopBtnClicked(sender: AnyObject) {
    APlayer.stop()
    APlayer.currentTime = 0
}
override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view, typically from a nib.

    _APlayer = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("Mirror Night", ofType: "mp3")!))
}_//此处有错误提示"call can throw,but it is not marked with 'try' and the error is nothandled"

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

解决方案
