JavaScript Enhancement Tutorial - Summary of Native.js Examples

Although Native.js is powerful and open, many web developers have difficulty completing it independently because they are not familiar with native APIs.
The purpose of this post is to summarize various written NJS codes for the convenience of web developers.
Everyone adds fuel to the flames. Competent developers can submit NJS code and everyone will give you a thumbs up.
Android platform
Create and delete App shortcuts on the desktop

见Hello H5+里Native.js部分演示及源码。
或在这里搜索“快捷方式”，http://ask.dcloud.net.cn/docs/ ... le/88调用Android本地分享 
 
获取安卓设备device.uuid 
 
数据读取 
打开网络设置 
调用系统控件播放视频 
 
调用讯飞的文字转语音功能（TTS） 
接收系统广播消息，如监听安装卸载apk的事件 
例说明如何使用Native.js进行BroadcastReceiver广播http://ask.dcloud.net.cn/question/7661常驻Android通知栏，不用个推实现本地消息推送(Local Notification)
 
开启个推推送功能
var pushManager = plus.android.importClass("com.igexin.sdk.PushManager");
var context = plus.android.runtimeMainActivity();
function enable() {
    pushManager.getInstance().turnOnPush(context);
}
function disable() {
    pushManager.getInstance().turnOffPush(context);
}

利用native.js获取手机gps是否开启http://ask.dcloud.net.cn/question/11890通过native.js设置系统墙纸http://ask.dcloud.net.cn/article/651iOS平台
获取包名
var NSBundle = plus.ios.importClass('NSBundle');
var bundle = NSBundle.mainBundle();
console.log(bundle.bundleIdentifier());
plus.ios.deleteObject(bundle);
获取设备名 
native.js登入game center
见Hello H5+里Native.js部分演示及源码。
或在这里搜索“game center”，http://ask.dcloud.net.cn/docs/ ... le/88设置获取内容到系统粘贴板 
 
base64数据保存为图片http://ask.dcloud.net.cn/question/6190设置webview滑动减速度
var webview = plus.ios.currentWebview();
var scrollView = webview.plusGetAttribute("scrollView");
scrollView.plusSetAttribute("decelerationRate:",0.99);
打开ios的Wifi设置页面 
http://ask.dcloud.net.cn/article/188ios获取系统的时区id
var NSTimeZone = plus.ios.importClass("NSTimeZone");
var sys = NSTimeZone.systemTimeZone();
console.log(sys.plusGetAttribute("name"));
状态栏显示网络请求雪花
var UIApplication = plus.ios.import("UIApplication");
var sharedApplication = UIApplication.sharedApplication();
sharedApplication.setNetworkActivityIndicatorVisible(true);
plus.ios.deleteObject(sharedApplication);
获取GPS授权状态
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:
      // This application is not authorized to use location services.  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).  Authorization to use
    // launch APIs has not been granted.
      break;
      case 5:
     // This value is deprecated, but was equivalent to the new -Always value.
      break;
      defalut:
      break;
}
获取手机存储空间
var BundleClass = plus.ios.importClass("NSBundle");
var BundleObj = BundleClass.mainBundle();
var filenamagerobj = plus.ios.newObject("NSFileManager");
var FileAttr = plus.ios.invoke(filenamagerobj,"attributesOfFileSystemForPath:error:",BundleObj.bundlePath(),null);
// NSFileSystemFreeSize 参数获取剩余空间
// NSFileSystemSize  获取手机总存储空间
var freeSpace = plus.ios.invoke(FileAttr,"objectForKey:","NSFileSystemFreeSize");
var numberFormatterObj = plus.ios.newObject("NSNumberFormatter");
var FreeSpaceStr = plus.ios.invoke(numberFormatterObj,"stringFromNumber:",freeSpace);
var freeSpace = FreeSpaceStr / 1024/1024/1024;
看完这些例子，是不是觉得JS特别强大？
赶快拿去用起来吧！
