我在使用Twilio客户端组件的Xamarin应用程序中崩溃了。我使用＆＃34;入门＆＃34;代码来制作一个简单的应用程序，当我点击一个按钮时，它会拨打电话。从崩溃日志中我看到对＆＃34; CRASHING_DUE_TO_PRIVACY_VIOLATION ＆＃34;的引用在调用堆栈中。我不知道那可能是什么，音频和Airplay＆＃34;和＃34; IP语音＆＃34;在我的应用程序plist文件中检查后台模式。
在模拟器中奇怪的是它完美无缺，只有当我在iPhone上运行应用程序时才会发生崩溃。我的手机正在运行ios 10.2。我包括代码和崩溃日志。请帮助，因为这个崩溃在我正在为工作而构建的应用程序中完全相同，所以我真的需要解决它而且我在我的智慧结束。

这是崩溃日志。请注意崩溃是在第7个线程中。

请确保您使用的是最新的iOS语音SDK 2.0 https://www.twilio.com/docs/api/voice-sdk/ios。您使用的Xamarin组件可能基于弃用版本（Twilio iOS Client SDK）。新版本是可编程语音iOS SDK，支持iOS 10.
changelog中的详细信息。
答案 1 :(得分：0)
如果缺少必需的权限字符串，则定位到iOS 10+的应用会崩溃。
对于Twilio，它需要访问手机的麦克风，因此您的应用需要询问用户麦克风使用权限。
您可以通过编辑应用的Info.plist文件来执行此操作。在<key>NSMicrophoneUsageDescription</key>
<string>My app needs to use the microphone.</string>部分中添加此代码<dict> ... </dict>。
有关详细信息，请参阅iOS 10 - Changes in asking permissions of Camera, microphone and Photo Library causing application to crash和https://developer.apple.com/library/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html。
