DMGesturedNavigationController

Beta: This is a very early release, refactors and more features, less bug too… are coming.

Feedbacks would be appreciated.

UINavigationController re-implementation the way Apple should have made it. Full gesture support for transition and navigation. With stack options and more

##Features

1. Support swipe gesture to navigation between child view controllers
2. Support both standard UINavigationController stack and a new one where you can navigate back and forth.
3. Full re-implementation of UINavigationController by subclassing UIViewController.
4. Provide a protocol for you to know when your view controller are visible, active, etc…
5. Far more to come.

##How to use it

Add the files from /classes to your project, import DMGesturedNavigationController and you're done.

It works like a UINavigationController, but it's not, it offer various other feature and powerful manipulation of the child view controller stack.

###Important

Take a look at the stackType property, it takes a DMGesturedNavigationControllerStackType option By default it is set to the new DMGesturedNavigationControllerStackNavigationFree DMGesturedNavigationControllerStackNavigationFree: Here the user can go back and forth between view controller (like it is actual pages of a book).

When you go back from a view controller it won't be removed from the hierarchy. You will still be able to navigate to it.

DMGesturedNavigationControllerStackLikeNavigationController work like a classic UINavigationController, if you go back, the previous view controller is removed from the hierarchy.

###Classic

You'll find the usual suspect

- (void)pushViewController:(UIViewController *)viewController
              animated:(BOOL)animated;
- (void)popViewConrollerAnimated:(BOOL)animated;
- (void)popToRootViewControllerAnimated:(BOOL)animated;
- (void)setNavigationBarHidden:(BOOL)navigationBarHidden animated:(BOOL)animated;

Which act the same if you are in DMGesturedNavigationControllerStackLikeNavigationController mode

###New

To accomodate with the new navigation mode I've added a few other method

- (void)pushViewController:(UIViewController *)viewController
              animated:(BOOL)animated
removeInBetweenViewControllers:(BOOL)removeInBetweenVC;

This one is interesting, you can push a new UIViewController and navigate to it, if you set removeInBetweenVC to No, it will preserve view controller betweeen the new pushed one and the last visible one you navigate from.

- (void)inserViewController:(UIViewController *)viewController
          atStackOffset:(NSInteger)offset
               animated:(BOOL)animated;
- (void)removeViewController:(UIViewController *)viewControlller
                animated:(BOOL)animated;
- (void)navigateToViewController:(UIViewController *)viewController 
						animated:(BOOL)animated;
- (BOOL)containViewController:(UIViewController *)viewController;

Those methods are documented. The new thing is that you can freely add or remove a VC in the stack and navigate to it.

###DMGesturedChildViewControllerNotifications

DMGesturedNavigationController provide a protocol for you to implement if you wish. You can implement the methods provided by this protocol, so you will be notified at the right time when your view controller become active, resign active etc…

You Should use thode methods instead of Apple one (viewDidAppear…) when working with a DMGesturedNavigationController.

##Know issues

1. The navigation bar stack is bugged when animated if you do too much transitions simultaneously.
2. The bottom toolbar is not implemented.
