iPhone - 检测第一次启动与phonegap [英] iPhone - detect first time launch with phonegap

问题描述

我试图检测第一次启动新安装的应用程序，并显示该应用程序的许可协议。用户必须接受lincense或离开应用程序。

I am trying to detect the first time launch of a newly installed application and display a license agreement for the application. The user must accept the lincense or leave the application..

有谁知道我可以如何使用Phonegap这样做？我已经通过主题搜索，但我似乎找不到这里。

Does anyone know how I can do this using Phonegap? I have searched through the topics but I cant seem to find this anywhere.

谢谢

推荐答案

您可以使用本机储存空间的应用程序启动计数。

You can use local storage to keep track of app launch counts.

var applaunchCount = window.localStorage.getItem('launchCount');

//Check if it already exists or not
if(applaunchCount){
   //This is a second time launch, and count = applaunchCount
}else{
  //Local storage is not set, hence first time launch. set the local storage item
  window.localStorage.setItem('launchCount',1);

  //Do the other stuff related to first time launch
}
