title: Post to Friend's Wall with iOS Facebook SDK
body: <p>Is it possible to use the iOS Facebook SDK's <code>dialog</code> method to post to the active user's friends' walls? That is, assuming the correct permissions have been granted?</p>
  
  <p>Using the dialog method, with <code>"feed"</code> as the action, only seems to allow me to post to the user's stream, not to anyone elses. What am I missing?</p>
  
  <p><code>[facebook dialog:"feed" andParams:... andDelegate:self]</code></p>
  
  <p>The <code>params</code> only specify the content of the post; there doesn't seem to be any way to specify the profile I want to post to. </p>
