Native.js虽然强大和开放，但很多web开发者因为不熟悉原生API而难以独立完成。
这篇帖子的目的就是汇总各种写好的NJS代码，方便web开发者。
众人拾柴火焰高，有能力的开发者多多提交NJS代码，大家都会给你点赞的，我们也会为每位共享NJS代码的朋友送上200积分。

Due // to active restrictions on location services, the user cannot change // this status, and may not have personally denied authorization break; case 2: // User has explicitly denied authorization for this application, or // location services are disabled in Settings. break; case 3: // User has granted authorization to use their location at any time, // including monitoring for regions, visits, or significant location changes. break; case 4: // User has granted authorization to use their location only when your app // is visible to them (it will be made visible to them if you continue to // receive location updates while in the background).

显示应用内的ViewController
复制代码// NewViewController为应用内创建的原生的ViewController类名,所调用页面的内容需要在原生代码中完成 var newVCobj = plus.ios.newObject("NewViewController"); var UIApplicationClass = plus.ios.importClass("UIApplication"); var UIAppObj = UIApplicationClass.sharedApplication(); var del = plus.ios.invoke(UIAppObj,"delegate"); // 如果当前应用delegate对象包含UIWindow对象并且变量名命名为“window”可以这么写， // 否则需要根据实际代码情况修改 // 应用的delegate对象也可以添加一个返回UIViewController的方法 var appWindowObj = plus.ios.invoke(del,"window"); var appRootController = plus.ios.invoke(appWindowObj,"rootViewController"); plus.ios.invoke(appRootController,"presentViewController:animated:completion:",newVCobj,"YES",null);
看完这些例子，是不是觉得JS特别强大？
赶快拿去用起来吧！
