应用程序在设备上调试时崩溃

问题描述：

我的应用程序在iOS模拟器上调试得很好，并且在构建和部署一个ipa文件到设备时它运行良好。但是，如果我尝试在设备上进行调试（iPhone 9.3.1和iPad 9.3），则应用程序会在启动时立即崩溃。我正在使用Visual Studio w/Xamarin。这个问题似乎是建立/配置/版本相关的，因为它在模拟器和IPA文件版本上工作正常，但我无法弄清楚问题所在。应用程序在设备上调试时崩溃

的Visual Studio 2013更新5 Xamarin 4.0.3.214 Xamarin.iOS 9.6.1.8

你看看你的应用程序的链接？请参阅：https：//developer.xamarin.com/guides/ios/advanced_topics/linker/ – Martijn00

是的。我以相同的结果关闭链接器。 –

在iOS项目的AppDelegate.FinishedLaunching中可能比模拟器需要更长的时间，例如设备的“看门狗”进程可能会杀死应用程序？ –

答

MtouchUseRefCounting

这可能是必需的。转到构建选项，高级选项卡，并在右侧打勾。它应该在调试模式/模拟器中打勾。因此，请在调试/设备中勾选它。

没有运气。仍然崩溃。 –

答

这是不是直接回答你的问题，但看MvvmCross source为MvxIosSystem.BuildVersion，27行确实出现执行ToArray其中，app的无效地址访问去世：

private void BuildVersion() 
{ 
    var version = UIDevice.CurrentDevice.SystemVersion; 
    var parts = version.Split('.').Select(int.Parse).ToArray(); 
    this.Version = new MvxIosVersion(parts); 
}

可能UIDevice.CurrentDevice.SystemVersion是返回MvvmCross框架意想不到的有趣事物？

I.e. version.Split('.').Select(int.Parse).ToArray()怎么会导致这个无效的访问？

也许你可以在MvvmCross启动发生之前在你的应用中使用类似的代码行来获得版本值，并希望有更多的线索去调试。

我想这在一个小Xamarin.iOS项目，就在Main.cs，但看不到任何会导致问题 - version回来了“9.3.1”和parts是一个数组int[3]：

public class Application 
{ 
    // This is the main entry point of the application. 
    static void Main (string[] args) 
    { 
     //Xamarin.Insights.Initialize (XamarinInsights.ApiKey); 
     var version = UIDevice.CurrentDevice.SystemVersion; 
     var parts = version.Split('.').Select(int.Parse).ToArray(); 

     // if you want to use a different Application Delegate class from "AppDelegate" 
     // you can specify it here. 
     UIApplication.Main (args, null, "AppDelegate"); 
    } 
}

我也试过version替代的，而不是调用UIDevice.CurrentDevice.SystemVersion一些有创意的价值，但我能生成是未处理的字符串格式或具有非常不同的iOS崩溃日志比你贴什么空引用例外。

我不知道设备重置是否可以解决问题，从this SO answer到类似的问题。

设备重置可能是答案，但它是我的个人电话，现在不是一个选项。 –

我仍然无法从我的设备进行调试，尽管您的答案没有修复，但它提供了深入的见解。 –

你有没有机会看到'UIDevice.CurrentDevice.SystemVersion'返回的值是什么？我很想知道设备是否触发'MvvmCross'代码崩溃，或者这是否更像物理内存问题。 –

答

我在本地应用程序的基础上回复，如果您在工程的构建设置中将“临时配置文件”设置为“调试”选项，则会发生这种情况。这意味着为了调试你的代码，你需要设置调试临时配置文件'调试'而不是临时配置文件。

对我来说并非如此 –
