initWithObjectsAndKeys: requires 2 arrays. One for the object and other for the key. You are passing only a single array. — Jasmeet Singh, Feb 24 '15 at 11:28

Your saved result is NSArray ie arrResult , so we will loop through it.

for(NSDictionary *dictObject in arrResult)
{
   //Get Data Dictionary
   NSDictionary *dictData = [dictObject valueForKey:@"data"];
  //Now have data so traverse
  for (NSString*strkey in dictData) {
        id value = [dictData objectForKey:strkey];
        NSLog(@"id = %@",value);
    }
}
