Xcode 运行时崩溃答案

【问题标题】：Crash on Xcode RunXcode 运行时崩溃
【发布时间】：2018-10-23 04:18:03
【问题描述】：

我运行从 Unity3D 导入的项目。然后在 XCode 我尝试运行到我的 iPad。

可以构建和安装应用程序，但运行时会崩溃（有时只是空白屏幕）。

在 Xcode 中出现以下错误，但我不明白这些错误是什么意思？

我在这里遇到了异常：

gsCrashReporterUEHandler    NSUncaughtExceptionHandler *    (flashcards`uncaught_exception_handler) 0x01bf1a38

任何想法，我在这里发现了什么错误？

【问题讨论】：

它或多或少地告诉你问题是什么“未捕获的异常：NSInternalInconsistencyException：只有在统一设置为自动旋转时才应使用 UnityDefaultViewController”..

标签： xcode unity3d exception crash

【解决方案1】：

在您的崩溃日志中，我可以看到以下错误：未捕获的异常：NSInternalInconsistencyException：UnityDefaultViewController 仅应在 unity 设置为自动旋转时使用。

这意味着 Unity 应该将 Screen.orientation 设置为 ScreenOrientation.AutoRotation。

您可以检查 Unity3D 项目中的某些代码是否将 Screen.orientation 设置为任何其他代码，并检查“Unity Build setting”中的默认方向是“Auto Rotation”。

【讨论】：

【解决方案2】：

我们也收到了这份崩溃报告，其中很多

我在某个地方（可能在 Unity 论坛中）读到它是由以不同方向显示的广告引起的，当游戏从广告返回时，方向没有正确恢复，因此 Unity 记录了 ASSERT。

嗯，我们做到了，它对我们有用！！！

他们建议我们只需要打开导出的 XCode 项目并注释掉文件 UnityViewControllerBase+iOS.mm 中的 ASSERT 行 111

//
// Just in case the attached screenshot expires
//
- (NSUInteger)supportedInterfaceOrientations
{
    //NSAssert(UnityShouldAutorotate(), @"UnityDefaultViewController     should be used only if unity is set to autorotate");

    return EnabledAutorotationInterfaceOrientations();
}
