Control cursor position in UITextField
<p>I have a UITextField that I'm forcing formatting on by modifying the text inside the change notification handler. This works great (once I solved the reentrancy issues) but leaves me with one more nagging problem.
If the user moves the cursor someplace other than the end of the string then my formatting change moves it to the end of the string. This means users cannot insert more than one character at a time into the middle of the text field. 
Is there a way to remember and then reset the cursor position in the UITextField?</p>
