Answer 1

Depends on your code:

NSMutableDictionary *gradedetails = [[NSMutableDictionary alloc] init];
[gradedetails setObject:@"pass" forKey:@"studentresult"];
[gradedetails setObject:@"provided" forKey:@"marksheet"];

NSMutableDictionary *results = [[NSMutableDictionary alloc] init];
[results setObject:gradedetails forKey:@"Grade1"];
[results setObject:@"01" forKey:@"ID"];
[results setObject:@"Name" forKey:@"Student1"];

NSMutableDictionary *stud = [[NSMutableDictionary alloc] init];
[stud setObject:results forKey:@"Students"];
