JKKeyboard

JKKeyboard keeps track of the keyboard frame, and lets you manage your scroll view insets along with custom views' frames the easy way, handling animations completely transparently for you. It will also help you scrolling down your scroll views with the keyboard when appropriate.

JKKeyboard.h

This file is the one you import when using JKKeyboard. It takes care of the other imports.

JKKeyboardObserver

A singleton class which gets initiated automatically, and observes the keyboard frame.

UIViewController+JKKeyboard

Implements the callback block as a property, so you just call...

self.keyboardMoveBlock = ^(__weak typeof(self) self, CGRect keyboardFrameInRootView, CGFloat keyboardIntersectionInRootView, CGFloat keyboardVisibility, BOOL shouldLayoutIfNeeded) {
	// tweak everything you need
	// look @ the demo project view controller implementation file for more
	
	if(shouldLayoutIfNeeded) {
		[self.view layoutIfNeeded];
	}
};

...in viewDidLoad:, and you're done :)

Note: The block doesn't get called after viewWillDisappear:, and starts again shortly after viewDidAppear: (calling it once to update your views, also for the first time).

Deallocation and rollback is performed automatically for you when your view controller is about to get deallocated, although if you want to do it earlier, you just set the keyboardMoveBlock to nil;

UIView+JKKeyboard

Easily obtain the information you need. You can access the keyboard frame and intersection anytime when you views are in the view hierarchy, and in any view using .keyboardFrameInView and .keyboardIntersectionInView properties of your UIViews.

UIScrollView+JKKeyboard

The main aim of this class is to simplify scrolling your scroll views to bottom when the keyboard is being shown. You're able to do something like...

if(scrollView.isScrolledToBottom) {
	scrollView.shouldScrollToBottomOnNextKeyboardWillShow = YES;
}

...in your text field's textFieldShouldBeginEditing: delegate callback, and your scroll view will do exactly what you'd expect.
