title: Mail Composer Address Problem
body: <p>I found email composer sample code from iphone OS Ref Library. Here is a code-</p>
  
  <p>Code:</p>
  
  <pre><code>NSArray *toRecipients = [NSArray arrayWithObject:@"first@example.com"];
  NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@example.com", @"third@example.com", nil];
  NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@example.com"];
  </code></pre>
  
  <p>My question is how to take user's input? Here all email address are predefined in code. so what are the IDs of to, CC, Bcc, subject and body fields?</p>
