попробовать это:

NSMutableDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error]; 
//responseData is an NSData object containing the jSON 

NSMutableArray *allData = [jsonDict objectForKey:@"all_data"]; 

for (NSDictionary* dict in allData) 
{ 
    NSString *eventID = [dict objectForKey:@"event_id"]; 
    NSLog(@"event ID : %@",eventID); 
}
