Suppose jsonDict is your json dictionary.... Try this

NSArray * keys=[[NSArray alloc]init];
keys=[jsonDict allKeys];
NSMutableArray *titles=[[NSMutableArray alloc]init];
for(int i=0;i<[keys count];i++){
      [titles addObject:[[jsonDict valueForKey:[keys objectAtIndex:i]]valueForKey:@"title"]];
}
NSLog(@"your array of titles : %@",titles); //use this array to fill your cell

@Neo, your first line is unnecessary -- you create an empty array and then assign the same variable to the array returned by allKeys. It should just be NSArray *keys = [jsonDict allKeys]; – rdelmar Oct 08 '12 at 05:45

Are you trying to parse the JSON yourself? You might find it easier to use something that's already well tested, such as TouchJSON or Apple's own NSJSONSerilization. The result should be a graph of Objective-C objects that you can use however you like.

In any case, what you've got there is the equivalent of a dictionary of dictionaries. If you have that as a NSDictionary called myJSONDictionary, you can say:

NSArray *theObjects = [myJSONDictionary allValues]; // gets all the objects
NSArray *theTitles = [theObjects valueForKey:@"**title**"]; // gets all the titles

You can also iterate through a dictionary using fast enumeration:

NSMutableArray *theTitles = [NSMutableArray array];
for (NSString *key in myJSONDictionary) {
    NSDictionary *object = [myJSONDictionary objectForKey:key];
    NSString *title = [object objectForKey:@"**title**"];
    [theTitles addObject:title]
}

There's no real advantage to doing that instead of using KVC as in the first example if you just need the titles, but it could be the right choice if you have more complex work to do for each object.

ok thanks. But, help me out bro. I just need some code that will parse the json object dynamically. In my question 0,1,2 are there, that may increase r decrease, So i want to parse all the keys dynamically. Plz plz — Joker, Oct 08 '12 at 05:25
