Question

我们基于Xamarin的iOS应用在iPhone上运行良好但在iPad上崩溃。违规通知是SetEnableIO：

audioUnit = new AudioUnit.AudioUnit(component);
audioUnit.SetEnableIO(true, AudioUnitScopeType.Input, kInputBus);

以下是调试窗口中收到的输出：

=================================================================
Got a SIGABRT while executing native code. This usually
indicates a fatal error in the mono runtime or one of the
native libraries used by your application.

有谁知道如何解决这个问题？问候。

环境：

Visual Studio 2015 with update 3
Xamarin 4.2.0.680
Xamarin.iOS 10.0.0.6
iPad is running iOS 10.0.1

Answer 1

我们终于把问题钉死了。显然，Xamarin还没有在iOS 10上进行过全面测试。操作系统引入了一些新的隐私设置。如果您没有定义iOS应用程序打算使用的设置，您将看到您的应用程序因SIGABRT错误而崩溃。可以在Info.plist.中定义隐私设置。在我们的案例中，它是NSMicrophoneUsageDescription.希望您觉得这很有用。
