There is way to much code. The substringToIndex and substringFromIndex are wrong, should not be in the code.

Use the literal syntax for the dictionaries:

NSDictionary *jsonDict = @{@"jsonData":@{@"password":password, @"empId":userName}};
NSData* jsonData =  [NSJSONSerialization dataWithJSONObject:jsonDict options:0 error:&error];
