Is is possible to resignFirstResponder, and still cut and paste?

The app needs a UITextView which supports Cut and Paste and/or Keyboard input.
When the keyboard appears, the UITextView can be reduced in size, so that
the Keyboard does not overlap it. I am able to paste text into the UITextView,
but now I want to have the TextView "full size" so that I can better select text to "cut and paste"
elsewhere. The Keyboard is in the way. My Newbie Question is:
Is is possible to make the KB disappear and stay hidden , i.e. resignFirstResponder, while at the same time maintaining the Cut,Paste etc. Menu and functionality, Select
text etc. in UITextView(full sized)? It seems that touching the view to "extend" text selection causes the Keyboard to reappear. I know I am failing to look at this problem correctly.
Many Thanks, Mark

I don't think it is possible, but in your place, I will try using UITextViewDelegate methods (- (BOOL)textViewShouldBeginEditing: (UITextView *)textView and - (BOOL)textViewShouldEndEditing: (UITextView *)textView).

However, if it is possible, how do you want to distinguish whether user wants the keyboard or not? The only thing that comes to my mind is to have a button: 'Show keyboard' or sth - but this may violate the HUG (Human Interface Guidelines) and Apple may reject your app! I have never seen an application that has the funcionality you described...

Thanks very much for your reply.
I do currently have a Button, tied to a BOOL, whose title toggles between "Hide KB" and "Enable KB". Thanks for the HUG heads up.

I decided the Hide/Enable button is kludgy. I decided to accept
the continuous presence of the KB. The code below needs Orientation
support but I think this is a good start. I hope this helps others trying to
deal with this situation.

- (void) handleKeyboardWillShowNSNotification *) note{
NSDictionary *info = [note userInfo];
/*UIKeyboardAnimationCurveUserInfoKey = 0;
UIKeyboardAnimationDurationUserInfoKey = 0.4;
UIKeyboardBoundsUserInfoKey = NSRect: {{0, 0}, {480, 162}};
UIKeyboardCenterBeginUserInfoKey = NSPoint: {240, 559};
UIKeyboardCenterEndUserInfoKey = NSPoint: {240, 239};
*/
NSValue *keyBounds = [info objectForKey:UIKeyboardBoundsUserInfoKey];

CGRect bndKey,tvFrame;
[keyBounds getValue:&bndKey];

/* bndKeys:: NSRect: {{0, 0}, {480, 162}} */ // landscape

tvFrame = pasteIDC_TextView.frame;
tvFrame.size.height -= bndKey.size.height;
[[self pasteIDC_TextView] setFrame:tvFrame];
}
