title: How can I cast an integer to an id in iOS
body: <p>My code is something like this:</p>
  
  <pre><code>[request setPostValue:employee.empId forKey:@"empId"];
  </code></pre>
  
  <p>where employee is a "POCO" object that has a property empId which is int, but the method is waiting an identifier.</p>
  
  <p>I've tried already sending setPostValue:&amp;employee.empId and setPostValue:[employee.empId] but still getting errors.</p>
  
  <p>Can I get the (id) in any way? or must I create another object from the property?</p>
