            "name": "Abc_A",
            "classIdentifier": "tag"
        },

Use the framework as pointed by Ehab Amer.
For parsing you can use this code snippest

SBJsonParser *sbjasonObj=[[[SBJsonParser alloc]init] autorelease];
NSMutableDictionary *categoriesContainer = [[NSMutableDictionary alloc]initWithDictionary:[sbjasonObj objectWithString:result]];

where result is JSON as your.
