my code here:

- (void)viewdidload {     [super viewdidload];     radataobject *category;     (nsdictionary *dict in jsonarray) {         nsarray *subarray = [dict valueforkey:@"sub"];         if(subarray.count ==0) {             category = [radataobject dataobjectwithname:[dict valueforkey:category_name_english] children:nil];         }         else {             category = [radataobject dataobjectwithname:[dict valueforkey:category_name_english] children:[self getsubcategories:subarray]];         }         [mutableaddarray addobject:category];     }     self.data = [mutableaddarray copy]; }  -(nsarray *)getsubcategories:(nsarray *)subarray {     nsmutablearray *duplicate = [[nsmutablearray alloc]init];     (nsdictionary *dct in subarray) {         [duplicate addobject:[dct valueforkey:category_name_key]];     }     nsarray *returnarray = [duplicate copy];     return returnarray; }

is possible using recursion?

this code might work your.. not checked..

-(void)getsubcategories:(nsarray *)subarray { (nsdictionary *mydict in subarray) {  nsstring *first = [mydict objectforkey : @"category_name_english"]; nsarray *myubarray = [mydict objectforkey : @"sub"]; if([mysubarray count])  [self getsubcategories:mysubarray];   } }

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
