I am fairly new to iOS development and I have been trying to figure out how I can convert the following string into an array and then displaying that array in a UITableView {"Result":"OK","Users":[{"name":"The King","email":"king@gmail.com"},{"name":"The Resteruant","email":"theresturaunt@gmail.com"}]} What I want to get is an array for the "name" and a separate array for "email" This is what i have so far: strURL = [NSString stringWithFormat:@" [LINK] "]; dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]]; strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding]; NSLog(@"%@", strResult); I have installed a JSON library but I dont know how to use i

In the arabic case you can use JSON_UNESCAPED_UNICODE for default behaviour like echo json_encode($yourdata, JSON_UNESCAPED_UNICODE); Also use charset=utf-8 also Read this [LINK] Try to get response in NSArray then convert it in JSON or see the video tutorial [this video] which may helps you.

I'm trying to parse a JSON from this URL [LINK] , which is a JSON output from Wordpress. For some reason, there's no output in the UITableView. Here's the code I have got to parse. I'm sure I'm missing out something but I'm not able to figure out how to parse Nested JSON in this code. ViewController.m: - (void)viewDidLoad { [super viewDidLoad]; self.title = @"News"; [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; NSURL *url = [NSURL URLWithString:@" [LINK] "]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [[NSURLConnection alloc] initWithRequest:request delegate:self]; // Do any additional setup after loading the view, typically from a nib. } - (void)con

This question is bit related to my earlier question I am newbie for iPhone application and trying to learn UITableView with JSON . I followed this video [this video] for learning. I created same example using Stoaryboard and also added new screen where I can add data. Now I was trying to delete the data. So what I did is thought is instead of below method, I will add button on each row and on clicking of that I will delete the data. - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath But I am not getting how I will get the row details and how to delete. Any help/ suggestion would be grateful. Below is h

Cites Kevin Kelly · 2013-01 · Stack Overflow · on “Splitting JSON topics into sections in tableview”

I am reading articles from a webserver, which come in JSON format, and displaying them in tableview. I want to implement section headers, with each section being a topic. So far there are only 3 topics and the code in 'numberOfSectionsInTableView' below correctly determines that there are 3 sections. My trouble is with the next function, 'numberOfRowsInSection'. I cannot figure out how to determine the number of rows in each section. I have looked at other answers on stack overflow and the reason none have helped me is that I have a variable number of sections and rows, whereas most other questioners have a fixed number of sections. Any ideas? FYI 'news' is the array of articles in JSON form

Cites Brian Barthold · 2014-02 · Stack Overflow · on “json elements not being passed to table view”

I have a simple JSON feed which I can parse and see in the console but I can't seem to get it to display in my table view. I am using Xcode 5.0.2. I am not sure why I can see it in the for loop when echoed to the console, but not in the table view. FYI, I am brand new to building in xcode and objective c and I am using this video tutorial [this video] as guide. My Json looks like this: [ { "first_name": "Bill" }, { "first_name": "Ted" }, { "first_name": "George" } etc... ] PhotoTableViewController.h #import #import "DisplayViewController.h" @interface PhotosTableViewController : UITableViewController { IBOutlet UITableView *mainTableView; NSArray *news; NSMutableData *data; } @end PhotoTableViewC
