title: Setting cursor position of UITextField
body: <p>I´ve looked at the monotouch samples and tried:</p>
  
  <pre><code>var range = new NSRange(selectionStart, 1);
  NumberTextField.SelectedTextRange = IndexedRange.GetRange(range);
  </code></pre>
  
  <p>But this causes this exception at runtime: Objective-C exception thrown. Name: NSInvalidArgumentException Reason: -[iOS_IndexedRange asRange]: unrecognized selector sent to instance 0x7d9bd690</p>
  
  <p>I also looked at a lot of objective-c versions but i cant figure out how to do them on monotouch.</p>
