JSON in iOS parse

NSString *responseString = [request responseString];
NSDictionary *dictionary=[responseString JSONValue];
NSArray *dic=[dictionary valueForKey:@"data"];

 for (int a=0; a<dic.count; a++) {
        NSInteger z=(NSInteger)a;
        NSLog(@"%@",[[dic objectAtIndex:a] objectForKey:@"nom"]);
    }

this is the file 

{"data":[ "",{"id":"1","nom":"hello","message":["",{"id":1,"nom":"dad"}]}, {"id":"2","nom":"hi","message":["",{"id":"1","nom":"marie"},{"id":"2","nom":"bob‌​"}]} ] }

When I want to parcour my json file, I saw the problem whith variable "a" in objectAtIndex because it's an integer, but if I try value 5 for exemple it's work's perfect.

Can you help me please.

Take a look at your data array... The very first object is an empty string. So, you're trying to send an objectForKey: message to it (believing that is a dictionary) and you get a crash. You should either remove your object or implement a logic that would try to inspect each object before trying to pull a value.
