Native.js示例汇总

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。

复制代码var CLLocationManager = plus.ios.import("CLLocationManager");
var authorizationStatus = CLLocationManager.authorizationStatus();
switch(authorizationStatus) {
      case 0:
      /// User has not yet made a choice with regards to this application
      break;
      case 1:

            plus.ios.invoke(device, "lockForConfiguration:", null);

            } else {
                plus.ios.invoke(device, "setTorchMode:", 0);
                plus.ios.invoke(device, "setFlashMode:", 0);
            }
            plus.ios.invoke(device, "unlockForConfiguration");
        }
    }

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！
