Populate UITableView with nested JSON

as the title suggest I'm trying to populate a UITableView from JSON. I get the json object which looks like 

  {
    applications: {
           iphone: {
             application: [
                            {
                              title: "Title",
                             },
                             {
                              title: "Title2",
                             },
                             {
                              title: "Title3",
                             }
                           ]
                      }
                     }
    }

it goes on like that, with several title fields nested inside of application.

I would like to use all the titles as my cell labels. I can get a list like so

for (int i = 0; i < 10; i++)
    {
        titleString = [[[[[result objectForKey:@"applications"] objectForKey:@"iphone"] objectForKey:@"application"] objectAtIndex:i] objectForKey:@"title"];
        NSLog(@"title %@", titleString);
    }

which does work, as in I can log the list of titles...but I know I'm going about this in the wrong way, I can't even figure out what myArray would be in the return [myArray count] in the numberOfRowsInSection method... totally lost here! help is appreciated!

First is Application dictionary
this Application dictionary has one dictionary of key iPhone
this iphoneDic has an array of Dictionary

NSMutableDictionary *applicationsDict = [response objectForKey:@"applications"];
NSMutableDictionary *iphoneDict = [applicationsDict objectForKey:@"iphone"];
NSMutableArray *applicationArray = [iphoneDict objectForKey:@"application"];

now in the method numberOfRowInSection: of table view return the array count 

return [applicationArray count]

now in the cellForRowAtIndexPath: mthod we will use this applicationArray
Use Array ...

NSMutableDictionary *titleDict = [applicationArray objectAtIndex:indexPath.row];
cell.titleLabel.text = [titleDict objectForKey:@"title"];

I hope this will help you

[[[result objectForKey:@"applications"] objectForKey:@"iphone"] objectForKey:@"application"] is going to return array, so better store this array and use it wherever is required as follows:

NSArray *titleArray = [[[result objectForKey:@"applications"] objectForKey:@"iphone"] objectForKey:@"application"];

To store this array you can use instance variable so that you can use it entire file.

You can store these titles in an array then use this array as datasource for the table. Your myArray would be the array your stored titles in.
