Jan 21, 2017 pm 04:01 PM

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.

    // 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;

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!
