xcode - Swift Error 未处理且未标记为 try

Question

自从我更新 Xcode 以来，我目前遇到了那段代码的错误

{!}Call can throw, but is not marked with 'try' and the error is not handled

   let soundURL = NSBundle.mainBundle().URLForResource("jump", withExtension: "caf")
            audioPlayer = AVAudioPlayer(contentsOfURL: soundURL!, fileTypeHint: nil)
            audioPlayer.numberOfLoops = -1
            audioPlayer.play()

Answer 1

该方法现在是可抛出的，所以您可以这样处理它:

do {
    audioPlayer = try AVAudioPlayer(contentsOfURL: soundURL!, fileTypeHint: nil)
    audioPlayer.numberOfLoops = -1
    audioPlayer.play()
} catch {

}
