iPhone SDK: TextView, Keyboard in Landscape mode

Question

Hello.

How do I make sure that the textview is shown and the keyboard is not obscuring the textview, while in landscape.

Using UICatalog I created a TextViewController which works. In it there are two methods for calling the keyboard and making sure that textView is positioned above the keyboard. his just works great in Portrait mode.

I got the Landscape mode working, but on the textView is still being put to the top of the iPhone to compensate for the keyboard in portrait mode.

I changed the methods for showing the keyboards.

Below is the code for this methods: (I will just let see the code for show, since the hide code will be the reverse..

- (void)keyboardWillShow:(NSNotification *)aNotification 
{
 UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
 if (orientation == UIInterfaceOrientationPortrait) {
   // the keyboard is showing so resize the table's height
  CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue];
  NSTimeInterval animationDuration = [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
  CGRect frame = self.view.frame;
  frame.size.height -= keyboardRect.size.height;
  [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
  [UIView setAnimationDuration:animationDuration];
  self.view.frame = frame;
  [UIView commitAnimations];
 } else if (orientation == UIInterfaceOrientationLandscapeLeft) {
  NSLog(@"Left"); // Verijderen later
  CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue];
  NSTimeInterval animationDuration = [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
  CGRect frame = self.view.frame;
  frame.size.width -= keyboardRect.size.height;
  [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
  [UIView setAnimationDuration:animationDuration];
  self.view.frame = frame;
  [UIView commitAnimations];
 } else if (orientation == UIInterfaceOrientationLandscapeRight){
  NSLog(@"Right"); // verwijderen later.
  CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue];
  NSTimeInterval animationDuration = [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
  CGRect frame = self.view.frame;
  frame.size.width -= keyboardRect.size.width;
  [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
  [UIView setAnimationDuration:animationDuration];
  self.view.frame = frame;
  [UIView commitAnimations];
 }

}

I know that I have to change the line frame.size.height -= keyboardRect.size.height but I do not seem to get it working.

I tried frame.size.width -= keyboardRect.size.height that did not work. Losing the keyboardRect and frame all together work, however off course the keyboard obscures the textview........

How do you put it on both Landscape and Portrait mode? table view content in Portrait mode and text view content(text) in Landscape mode??

And How can we get equal spacing between 2 paragraph?

If you think you need different code for the different orientations, you're doing something else wrong. Once the orientation has changed and your superview has responded, the value that needs changing should always be the frame's height.
