检测应用程序首先启动Windows Phone [英] Detect app first launch windows phone

问题描述

我对 Windows Phone 开发人员很陌生.我想检测用户何时首次启动我的应用程序以显示解释框架，例如调用:

I'm quite new on windows phone dev. I would like to detect when the user launches my app for the first time to display an explaination frame for example by calling :

if(firstLaunch)
showTheFrameToTheGuyBecauseHeLaunchedTheAppForTheFirstTime();

如果有人能向我们展示这么小的脚本，我会非常高兴......

I would be sooooooo glad if someone could show us such a small script...

提前谢谢你们！

推荐答案

我建议您使用内置的应用程序设置.

I would recommend you to use the builtin applicationsettings.

const string settingsAppLaunched = "appLaunched";

public static bool IsFirstLaunch(){
    IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;
    return !(settings.Contains(settingsAppLaunched) && settings[settingsAppLaunched]);
}

public static bool Launched(){
    if(IsFirstLaunch()){
        IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;
        settings.Add(settingsAppLaunched, true);
        settings.Save();
    }
}

//usage:
if(IsFirstLaunch()){
    showTheFrameToTheGuyBecauseHeLaunchedTheAppForTheFirstTime();
    Launched();
}
