Question

我想使用Optimizely改进App中的A / B测试。为此，我实现了一个等于此repo的Xamarin Binding：

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

当我以这种方式在FinishedLaunching上注册我的API密钥时：

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

我的Optimizely的Info.plist节点是：

        <dict>
            <key>CFBundleURLName</key>
            <string>com.optimizely</string>
            <key>CFBundleURLSchemes</key>

            <string>Images.xcassets/AppIcons.appiconset/Icon-Small@2x</string>
        </dict>

其中optlyprojectid = optly + projectid（在我的api密钥中）。

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

可以找到绑定文件here

将SDK中的Optimizely库文件的副本放入与文件Optimizely.linkwith.cs相同的目录中
该项目现在应该在Xamarin中构建并生成.dll文件
现在在目标应用程序项目中，添加对上述.dll文件的引用，或者在解决方案中包含绑定项目并向其添加项目引用。
将com.optimizely URL方案添加到plist文件（根据xcode项目）
在AppDelegate.FinishedLaunching中添加与此类似的代码：

 


public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
    // create a new window instance based on the screen size
    window = new UIWindow(UIScreen.MainScreen.Bounds);

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


}

添加导出的属性＆＃34; Window＆＃34; :(不是100％确定是否需要）

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

在
[Export("window")] UIWindow window { get; set; }中，这个：
```
AppDelegate.OpenUrl
```
对于ABTesting，C＃不支持Objective-C Optimizely标头使用的C风格的宏，所以我设置了一个静态类来封装我们所有的A / B变量。目前我们只有一个整数变量＆＃34; onboardingExperience＆＃34;。


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

然后在其他地方我们只是引用


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));

}

注意：

由于Xamarin库执行的线程检查被Optimizely SDK违反，因此绘制Optimizly in-app手势可能会使调试模式版本中的应用程序崩溃。（这可能只发生在子类UIView类中 - 例如：对我们来说，它在UIButton的子类中崩溃了。）

并非所有Optimizely SDK都受到约束。有些功能和API需要在ApiDefinition.cs中写入适当的签名来支持这些功能。

简化变量实现会很好，所以它不是那么冗长/重复 - 也许用C＃反射和属性驱动它。

使用Xamarin绑定启动Optimizely时出错
