我的应用程序在iOS模拟器上调试很好，当我构建ipa文件并将其部署到设备时，它运行正常。但是，如果我尝试在设备上调试（iPhone 9.3.1和iPad 9.3），应用程序会在启动时立即崩溃。我正在使用Visual Studio w / Xamarin。问题似乎是构建/配置/版本相关，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。
Visual Studio 2013 Update 5 Xamarin 4.0.3.214 Xamarin.iOS 9.6.1.8

这不是您问题的直接答案，但查看MvxIosSystem.BuildVersion的{{3}}，第27行确实会执行ToArray应用程序因无效地址访问而死亡的情况：
private void BuildVersion()
{
var version = UIDevice.CurrentDevice.SystemVersion;
var parts = version.Split('.').Select(int.Parse).ToArray();
this.Version = new MvxIosVersion(parts);
}
MvvmCross框架可以UIDevice.CurrentDevice.SystemVersion返回一些有意外的意外吗？
即。 version.Split('.').Select(int.Parse).ToArray()如何导致此无效访问？
也许你可以在MvvmCross启动之前在应用程序中使用类似的代码行来获取版本值，并希望有更多的线索来调试。
我在一个小的Xamarin.iOS项目中尝试了这个，就在Main.cs中，但看不到会导致问题的任何内容 - 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");
}
}
我还尝试用version替换一些创意值而不是调用UIDevice.CurrentDevice.SystemVersion，但我生成的所有内容都是未处理的字符串格式或空引用异常，其iOS崩溃日志与您发布的完全不同。
我想知道设备重置是否可以解决问题，从MvvmCross source到类似的问题。
答案 1 :(得分：1)
我在本机应用程序的基础上进行回复，如果您在项目的构建设置中将Adhoc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，为了调试代码，您需要为调试＆＃39; Debug＆＃39;设置调试临时配置文件。不是特殊类型的临时档案。
答案 2 :(得分：0)
MtouchUseRefCounting
这可能是必需的。转到构建选项，高级选项卡，然后勾选右侧的框。它应该在调试模式/模拟器中勾选。所以在调试/设备中勾选它。
