<p><blockquote>
<p>The easiest way to disable pasteboard operations is to create a subclass of UITextView that overrides the canPerformAction:withSender: method to return NO for actions that you don't want to allow:</p>
</blockquote>
<pre><code>- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if (action == @selector(paste:))
return NO;
return ;
}
</code></pre>
