iOS 7 - Keyboard animation

Question

I\'m trying to understand the new keyboard animation in iOS 7.0 on the iPhone 5 Simulator. I want to resize my UITableView when the keyboard appears, but I can\

Answer 1

Register for the notification:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];

Respond by animating a change to the frame.origin.y of the view.

- (void)keyboardWillShow:(NSNotification *)aNotification {

    NSDictionary *userInfo = aNotification.userInfo;
    NSValue *endFrameValue = userInfo[UIKeyboardFrameEndUserInfoKey];
    CGRect keyboardEndFrame = [self.view convertRect:endFrameValue.CGRectValue fromView:nil];

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

    CGRect searchButtonFrame = self.searchButton.frame;
    searchButtonFrame.origin.y = (keyboardEndFrame.origin.y - searchButtonFrame.size.height);
    self.searchButton.frame = searchButtonFrame;

    [UIView commitAnimations];
}
