Swift 没有太多信息的崩溃报告

Question

我在 swift 为我们公司开发的所有应用程序都收到了同样的基本崩溃报告。它只发生在一小部分时间。没有太多信息可以参考。我们的应用程序显示的唯一一行是 AppDelegate.swift 无论如何我都没有编码。

我该如何解决这个问题？

Answer 1

这原来是一个与 AVAudioPlayer 相关的问题。我有一个 class AVAudioPlayer 变量 (audioPlay)，我一遍又一遍地为不同的声音重新初始化。在初始化我的变量之前，我停止了当前变量并使用以下代码将其重置为 nil。现在我没有问题了。

if audioPlay != nil
    {
        //print( "blabla" )
        audioPlay?.stop()
        audioPlay = nil
    }
