How to re-size UITextView when keyboard shown with iOS 7

Question

I have a view controller which contains a full-screen UITextView. When the keyboard is shown I would like to resize the text view so that it is not hidden under

Answer 1

i had done it and its work completely.

  #define k_KEYBOARD_OFFSET 95.0

-(void)keyboardWillAppear {
    // Move current view up / down with Animation
    if (self.view.frame.origin.y >= 0)
    {
        [self moveViewUp:NO];
    }
    else if (self.view.frame.origin.y < 0)
    {
        [self moveViewUp:YES];
    }
}

-(void)keyboardWillDisappear {
    if (self.view.frame.origin.y >= 0)
    {
        [self moveViewUp:YES];
    }
    else if (self.view.frame.origin.y < 0)
    {
        [self moveViewUp:NO];
    }
}

-(void)textFieldDidBeginEditing:(UITextField *)sender
{
    //if ([sender isEqual:_txtPassword])
   // {
        //move the main view up, so the keyboard will not hide it.
        if  (self.view.frame.origin.y >= 0)
        {
            [self moveViewUp:YES];
        }
    //}
}

//Custom method to move the view up/down whenever the keyboard is appeared / disappeared
-(void)moveViewUp:(BOOL)bMovedUp
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.4]; // to slide the view up

    CGRect rect = self.view.frame;
    if (bMovedUp) {
        // 1. move the origin of view up so that the text field will come above the keyboard
        rect.origin.y -= k_KEYBOARD_OFFSET;

        // 2. increase the height of the view to cover up the area behind the keyboard
        rect.size.height += k_KEYBOARD_OFFSET;
    } else {
        // revert to normal state of the view.
        rect.origin.y += k_KEYBOARD_OFFSET;
        rect.size.height -= k_KEYBOARD_OFFSET;
    }

    self.view.frame = rect;

    [UIView commitAnimations];
}

- (void)viewWillAppear:(BOOL)animated
{
    // register keyboard notifications to appear / disappear the keyboard
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWillAppear)
                                                 name:UIKeyboardWillShowNotification
                                               object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWillDisappear)
                                                 name:UIKeyboardWillHideNotification
                                               object:nil];
}

- (void)viewWillDisappear:(BOOL)animated
{
    // unregister for keyboard notifications while moving to the other screen.
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:UIKeyboardWillShowNotification
                                                  object:nil];

    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:UIKeyboardWillHideNotification
                                                  object:nil];
}
