// NSFileSystemSize  获取⼿机总存储空间
var freeSpace = plus.ios.invoke(FileAttr,"objectForKey:","NSFileSystemFreeSize");

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);
