Get your View displaying properly in Landscape on iPhone and iPad
There are a number of articles that describe how to fit your view in the available space when the keyboard is being displayed. So the keyboard does not cover the UIView. But I haven't seen one that covers the situation when the orientation is landscape.

The trick here is that although the view is aware of the orientation, the keyboard is not. This means in Landscape, the keyboards width is actually its height and visa versa. So I've posted a number of methods but the keyboardWillShow method is the one of most interest. And in particular, the line
textView.frame = CGRectMake(0, 0, size.width , size.height - keyboardSize.width + 50);

Note that the keyboards width property is accessed to recalcuate the textviews height:

- (void) viewDidLoad {

    [super viewDidLoad];
    //Do stuff

    // Listen to keyboard show and hide events
 	// listen for keyboard
	[[NSNotificationCenter defaultCenter] addObserver:self 
	[[NSNotificationCenter defaultCenter] addObserver:self 

- (void) keyboardWillShow:(NSNotification *)notification {
    CGSize keyboardSize = [[[notification userInfo] 
    UIInterfaceOrientation orientation = 
        [[UIApplication sharedApplication] statusBarOrientation];
    CGSize size = self.view.frame.size;
    if (orientation == UIDeviceOrientationPortrait 
        || orientation == UIDeviceOrientationPortraitUpsideDown ) {
	textView.frame = CGRectMake(0, 0, 
                                   size.height - keyboardSize.height + 50);
    } else {
	//Note that the keyboard size is not oriented
        //so use width property instead	
	textView.frame = CGRectMake(0, 0, 
                                   size.height - keyboardSize.width + 50);

- (void) keyboardWillHide:(NSNotification *)notification {

    textView.frame = CGRectMake(0, 0, 
                               self.view.frame.size.height + 25);

- (void) dealloc {

    [[NSNotificationCenter defaultCenter] removeObserver:self];
