JSON parsing UITableViewController

Question

I'm trying to pass my JSON Data into the UITableViewController. I did manage to pass one of my JSON into the UITableView and display it on the next ViewController when the user performsegue. The problem is that I got 4 of my JSON Data that I want it to this display on the ViewController. I can't do the ObjectForKey due to the format of my JSON.

Here is my JSON

{
    uid: "60",
    name: "pae1344",
    mail: "[email protected]",
    theme: "",
    signature: "",
    signature_format: "plain_text",
    created: "1396189622",
    access: "0",
    login: "1396189622",
    status: "1",
    timezone: "Asia/Bangkok",
    language: "",
    picture: "0",
    init: "[email protected]",
    data: null,
    uri: "http://localhost/drupal/rest/user/60"
},

Here is the code from the myTableViewController.

#import "TestinViewController.h"
#import "AFNetworking.h"
#import "TestinCell.h"
#import "EDscriptionViewController.h"
@interface TestinViewController ()

@end

@implementation TestinViewController

- (id)initWithStyle:(UITableViewStyle)style

    self = [super initWithStyle:style];
    if (self) {
        // Custom initialization
    }
    return self;
}

    [super viewDidLoad];
    self.finishedGooglePlacesArray = [[NSArray alloc] init];
    [self makeRestuarantsRequests];

Is there a way for me to make my JSON into a Dictionary so, I can select what to be shown by using ObjectForKey ?

The best way to parse dictionary is Create an NSObject class and parse from there, and make objects. — Vineesh TP

First of all use this library by adding .m and .h files to your project:

JSONKit

Then you can turn JSON strings into dictionary.

//JSONString is a NSString variable with the JSON
NSDictionary *myJSONDic = [JSONString objectFromJSONString]
NSLog(@"User Id is : %@",[myJSONDic valueForKey:@"uid"]);

You can directly store your JSON response to NSDictionary. Than just check the print results of that Dictionary. You will be able to access the values by key.

Here is example :

NSDictionary *myDic = // JSON response;
NSLog(@"User Id is : %@",[myDic valueForKey:@"uid"]);

Hope this will help you.

sry I just found another problem after changing from NSArray to NSDictionary for my JSON response.In the CellForRowIndexPath how should I implement that ? cell.txtEnterPriseName.text = [self.googlePlacesArrayFromAFNetworking objectAtIndex:indexPath.row]; Thank you.

Mayur Prajapati - MeProgrammer Over a year ago

You can pass like this : cell.txtEnterPriseName.text = [yourDicName valueForKey@"name"];

Thank you very much for all your help but...... I come across another problem again T__T It seems that by passing like that it will only pass 1 value which is in this example is name to the next viewController(Not on the UItableviewController). How should I implement this in such a way that I can just pass 1 JSON as a block/group then classifying the valueForKey to match up with each UILabel.text after the user performsegue? Sorry for asking too many question.
