用Xamarin Binding启动Optimizely时出错。

我希望使用Optimizely来改进应用程序中的A/B测试。为此，我已经实现了一个类似于这个repo的Xamarin绑定：

https://github.com/JustGiving/XamarinBindings/tree/master/Optimizely.iOS

当我在FinishedLaunching中注册我的API密钥时，采用以下方式：

static readonly string OptimizelyAPIToken = "mykey~projectid";

public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
      // create a new window instance based on the screen size
      Window = new UIWindow(UIScreen.MainScreen.Bounds);
      root = new WelcomeController();
      nav = new UINavigationController(root);

      // If you have defined a root view controller, set it here:
      Window.RootViewController = nav;

      // make the window visible
      Window.MakeKeyAndVisible();

      OptimizelyiOS.Optimizely.SharedInstance().VerboseLogging = true;

      OptimizelyiOS.Optimizely.StartOptimizelyWithAPIToken(OptimizelyAPIToken, launchOptions ?? new NSDictionary());


      return true;
}

我有这个问题

这可能有所帮助，但Optimizely确实有一个基本的Xamarin绑定 - 我很想知道这是否有所帮助：

可以在此处找到绑定文件：这里 1. 将来自SDK的Optimizely库文件的副本放置在与Optimizely.linkwith.cs文件相同的目录中 2. 项目现在应在Xamarin中构建并生成.dll文件 3. 现在，在目标应用程序项目中，要么添加对上述.dll文件的引用，要么将绑定项目包含在解决方案中并向其添加项目引用。 4. 将com.optimizely URL方案添加到plist文件中（按照xcode项目） 5. 在AppDelegate.FinishedLaunching中添加类似于以下代码的代码：

公共覆盖布尔值FinishedLaunching(UIApplication app, NSDictionary options) { // 根据屏幕大小创建一个新的窗口实例 window = new UIWindow(UIScreen.MainScreen.Bounds);

ABTesting.Preregister();
Optimizely.Optimizely.SharedInstance.VerboseLogging = true;
Optimizely.Optimizely.StartWithAPIToken("***YOURTOKEN***", options);

}

Add an exported property "Window": (not 100% sure if this is needed)
[Export("window")] UIWindow window { get; set; }

In AppDelegate.OpenUrl, this:


public override bool OpenUrl(UIApplication application, NSUrl url, string sourceApplication, NSObject annotation)
{
    if (Optimizely.Optimizely.HandleOpenUrl(url))
        return true;
}

For ABTesting, C# doesn't support C-style macros as used by the Objective-C Optimizely headers, so I've set up a static class to encapsulate all our A/B variables. Currently we have just one integer variable "onboardingExperience".


public static class ABTesting
    {
        public static void Preregister()
        {
            Optimizely.Optimizely.Preregister(_onboardingExperienceKey);
        }

    public static int OnboardingExperience
    {
        get
        {
            return Optimizely.Optimizely.NumberForKey(_onboardingExperienceKey).IntValue;
        }
    }

    static OptimizelyVariableKey _onboardingExperienceKey = 
        OptimizelyVariableKey.Create("onboardingExperience", NSNumber.FromInt32(0));

}

然后，在其他地方我们只需要引用ABTesting.OnboardingExperience

备注:

在 Debug 模式下，通过绘制 Optimizly 的应用手势可能会导致应用程序崩溃，原因是由 Optimizely SDK 违反了 Xamarin 库执行的线程检查。 (这可能仅针对子类化的 UIView 类 - 例如：对于我们来说，它会在 UIButton 的子类中崩溃)。

并非所有 Optimizely SDK 都被绑定。有些功能和 API 需要在 ApiDefinition.cs 中编写相应的签名才能支持这些功能。

希望可以简化变量实现方式，使其不那么冗长重复 - 或许可以使用 C# 反射和属性来驱动它。

祝好运！
