title: UITextField property keyboardType not showing as expected
body: <p>I have a popover that accepts input into a UITextField. Depending on the input, I set the properties: text, keyboardType, returnKeyType, and keyboardAppearance. The text and returnKeyType properties are reflected in the popover. But I get a standard keyboard, with numbers (UIKeyboardTypeNumberPad, UIKeyboardTypeDecimalPad) or letters (UIKeyboardTypeDefault) showing. I expected to see the "enter pin" keyboard for UIKeyboardTypeNumberPad and numbers with a period for the UIKeyboardTypeDecimalPad keyboardType.</p>
  
  <p>My code...</p>
  
  <p>.h:</p>
  
  <pre><code>@interface IFDTextPopoverContentViewController : UIViewController {
  UILabel *notes;
  UITextField *input;
  }
  
  @property (nonatomic, retain) IBOutlet UILabel *notes;
  @property (nonatomic, retain) IBOutlet UITextField *input;
  </code></pre>
  
  <p>.m:</p>
  
  <pre><code>        IFDTextPopoverContentViewController *textPopover = (IFDTextPopoverContentViewController *)textPopoverController.contentViewController;
          textPopover.input.text = [xmlResults valueForKey:question.XmlAttrib];
          textPopover.input.keyboardType = UIKeyboardTypeNumberPad;
          textPopover.input.keyboardAppearance = UIKeyboardAppearanceDefault;
          textPopover.input.returnKeyType = UIReturnKeyDone;
          textPopover.notes.text = question.Notes;
  </code></pre>
  
  <p>Am I missing something to change the keyboardType? I am currently running this on an iPad. I have not tested on an iPhone. </p>
  
  <p>Another option might be to add a numeric or numeric+decimal keypad to the popover, but I do not know where to start on this option.</p>
