AVAudio Player中的iOS 13.1崩溃 [英] iOS 13.1 Crash in AVAudio Player

问题描述

当我跟踪问题时，我的应用程序在iOS 13.1上崩溃，然后发现由于AVAudioPlayer而导致应用程序崩溃.

My App is crashing on iOS 13.1 when i trace a issue then found App is crashing because of AVAudioPlayer.

下面是我的播放器设置.

Below Is My Player Setup.

if let wrongURL = Bundle.main.url(forResource: "wrongAudio", withExtension: "mp3")
        {
            do {
                wrongMusicPlayer = try AVAudioPlayer(contentsOf: wrongURL)
                wrongMusicPlayer.prepareToPlay()
            }
            catch
            {
                print(error.localizedDescription)
            }
        }

这里所有东西都可以正确找到，但是当AVAudioPlayer尝试用URL初始化时会崩溃.

Here All things found correctly but crash when AVAudioPlayer try to initialise with URL.

推荐答案

我在AVAudioPlayer的iOS 13.1中发现了崩溃问题.

I found a crash issue in AVAudioPlayer with iOS 13.1.

这是解决方案

为什么我的AVAudioPlayer崩溃?因为

我像

var wrongMusicPlayer: AVAudioPlayer = AVAudioPlayer()

然后我尝试如下重新分配wrongMusicPlayer

and then i try to reassign wrongMusicPlayer as below

wrongMusicPlayer = try AVAudioPlayer(contentsOf: wrongURL)

我的应用崩溃了.

解决方案

如果您以任何方法将AVAudioPlayer初始化为var wrongMusicPlayer: AVAudioPlayer = AVAudioPlayer()或wrongMusicPlayer = AVAudioPlayer()，请先将其删除，然后像var wrongMusicPlayer: AVAudioPlayer!那样声明.

If you initialise your AVAudioPlayer like var wrongMusicPlayer: AVAudioPlayer = AVAudioPlayer() OR wrongMusicPlayer = AVAudioPlayer() in any method then please remove it and just Declare like var wrongMusicPlayer: AVAudioPlayer!.
