UIViewController+KeyboardAdditions category simplifies keyboard handling logic by extending UIViewController class with several simple methods. Supports both AutoLayout and frame-based animations.

1. Import category #import <UIViewController-KeyboardAdditions/UIViewController+KeyboardAdditions.h>

2. Register to keyboard notifications in -viewWillAppear::

[self ka_startObservingKeyboardNotifications];

3. Unregister from notifications in -viewWillDisappear::

[self ka_stopObservingKeyboardNotifications];

4. Perform any layout with same animation options as keybord:

- (void)ka_keyboardShowOrHideAnimationWithHeight:(CGFloat)height
                               animationDuration:(NSTimeInterval)animationDuration
                                  animationCurve:(UIViewAnimationCurve)animationCurve {

    self.containerViewBottomConstraint.constant = height;
    [self.view layoutIfNeeded];
}

To run the example project, clone the repo, and run pod install from the Example directory first.
