Objective c, reposition a view above the keyboard in one single animation


Objective c, reposition a view above the keyboard in one single animation

it should still fix some issue You better use UIKeyboardWillChangeFrameNotification notification.
Add observer first.
code :
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardFrameChange:) name:UIKeyboardWillChangeFrameNotification object:nil];
- (void)keyboardFrameChange:(NSNotification *)notification {
    CGRect begin        = [[notification.userInfo valueForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue];
    CGRect end          = [[notification.userInfo valueForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
    CGFloat keyboardSize= begin.size.height;
    BOOL isShowing      = begin.origin.y > end.origin.y;

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:[notification.userInfo[UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
    [UIView setAnimationCurve:[notification.userInfo[UIKeyboardAnimationCurveUserInfoKey] integerValue]];
    [UIView setAnimationBeginsFromCurrentState:YES];

    // do view animation here.

    [UIView commitAnimations];
}

Any of those help I know that this is an old question, but the other answer is not good. The problem here is that you're used to the iPhone UI, which usually uses the Return button to close the keyboard. This is not the case on the iPad.
On the iPad, when the user taps the "hide keyboard" button, the UIKeyboardWillHideNotification is called, so you should register an observer for that notification.
code :
- (void)viewDidLoad {
  [[NSNotificationCenter defaultCenter] addObserver:self
                                           selector:@selector(keyboardWillHideHandler:)
                                               name:UIKeyboardWillHideNotification
                                             object:nil];
  // ...
}

- (void) keyboardWillHideHandler:(NSNotification *)notification {
    //code for pushing the view back down
}

I wish did fix the issue. For the delay problem you can use UIKeyboardWillShowNotification as Eugene Zaychenko suggest. it will solve your issue.
code :
[center addObserver:self selector:@selector(willShow:) name:UIKeyboardWillShowNotification object:nil];
- (void)didHide
{
    self.textViewPOS.constant = 0;
    NSLog(@"Closed");

    [UIView animateWithDuration:1 delay:0 options:0 animations:^{

        self.textViewPOS.constant = 0;
        [self.view layoutIfNeeded];

    } completion:nil];

}

- (void)willShow:(NSNotification *)notification
{
    CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    [UIView animateWithDuration:1 delay:0 options:0 animations:^{

        self.textViewPOS.constant = keyboardSize.height;
        [self.view layoutIfNeeded];

    } completion:nil];

    NSLog(@"Opened");
}

around this issue I'm doing a chatroom somewhat simular in style(not really a clone) to iphone sms, however I when used on an actual mobile device the text input gets centered on the screen and zoomed in, making it impractical for those devices. How can I cause the text input to be closer to(or better yet underneath) the virtual keyboard instead of centered in the screen. I don't have any none-ios devices to try this on but I assume simular problems occurs on other webkit mobile browsers. , Add this to your header:

like below fixes the issue Implement UIKeyboardDidShowNotification and UIKeyboardWillHideNotification and so you can do the Web-view reposition .
