應用程序在設備上調試時崩潰

[英]App Crashes when debugging on device

 原文  2016-04-21 13:45:46  6   3    ios/ xamarin/ xamarin.ios/ mvvmcross

問題描述

我的應用程序在iOS模擬器上調試很好，當我構建ipa文件並將其部署到設備時，它運行正常。 但是，如果我嘗試在設備上調試（iPhone 9.3.1和iPad 9.3），應用程序會在啟動時立即崩潰。 我正在使用Visual Studio w / Xamarin。 問題似乎是構建/配置/版本相關，因為它在模擬器和IPA文件版本上工作正常，但我無法弄清楚問題。

Visual Studio 2013 Update 5 Xamarin 4.0.3.214 Xamarin.iOS 9.6.1.8

有效的構建之間的項目配置：

3 個解決方案

解決方案1

這不是你問題的直接答案，但是看看MvxIosSystem.BuildVersion的MvvmCross源 MvxIosSystem.BuildVersion ，第27行確實會執行ToArray ，其中應用程序在無效地址訪問時死亡： 

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

UIDevice.CurrentDevice.SystemVersion可以通過MvvmCross框架返回一些有意思的意外嗎？

即如何version.Split('.').Select(int.Parse).ToArray()導致這種無效訪問？

也許您可以在MvvmCross啟動之前在應用程序中使用類似的代碼行來獲取版本值，並希望有更多的線索來調試。

我在一個小的Xamarin.iOS項目中嘗試了這個，就在Main.cs中，但是看不到任何會導致問題的東西 - version回來了“9.3.1”， parts是一個數組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");
    }
}

我還嘗試用一些創意值替換version而不是調用UIDevice.CurrentDevice.SystemVersion ，但我可以生成的是未處理的字符串格式或空引用異常，其iOS崩潰日志與您發布的完全不同。

我想知道設備重置是否可以解決問題，從這個回答類似的問題。

我在原生應用程序的基礎上回復，如果您在項目的構建設置中將Adhoc臨時配置文件設置為調試選項，則會發生這種情況。 這意味着，為了調試代碼，您需要為“Debug”設置調試臨時配置文件，而不是adhoc類型的臨時配置文件。

MtouchUseRefCounting

這可能是必需的。 轉到構建選項，高級選項卡，然后勾選右側的框。 它應該在調試模式/模擬器中勾選。 所以在調試/設備中勾選它。
