NavigationControllerWithBlocks 0.0.1

The UINavigationController missing methods ! (push / pop with optional completionBlock). The implementation use the navigationController delegate on UINavigationController itself.

This project provides :

A completionBlock to manage your push/pop events,
A safe way to push/pop multiple controllers at the same times.

   [self.navigationController popViewControllerAnimated:YES withCompletionBlock:NULL];
   [self.navigationController popViewControllerAnimated:YES withCompletionBlock:NULL];
   [self.navigationController popViewControllerAnimated:YES withCompletionBlock:NULL];

No more "Nested pop animation can result in corrupted navigation bar",
No more "Finishing up a navigation transition in an unexpected state. Navigation Bar subview tree might get corrupted."
No more crash because of deallocated controllers between your multiple animations.

New methods

- (void)pushViewController:(UIViewController *)viewController 
                 animated:(BOOL)animated 
      withCompletionBlock:(JMONavCompletionBlock)completionBlock;

- (void)popViewControllerAnimated:(BOOL)animated 
              withCompletionBlock:(JMONavCompletionBlock)completionBlock;
- (void)popToRootViewControllerAnimated:(BOOL)animated
                    withCompletionBlock:(JMONavCompletionBlock)completionBlock;

Usage

using category (UINavigationController+CompletionBlock), just call the method to activate auto delegation.

- (void)activateCompletionBlock;

and use the pop/push methods

[self.navigationController popViewControllerAnimated:YES withCompletionBlock:NULL];
[self.navigationController pushViewController:vc animated:YES withCompletionBlock:^(BOOL successful) {
   NSLog(@"Hi ! Push done !");
}];

using JMONavigationController (subclassing UINavigationController), nothing to be done, default initalizers are overided to call activateCompletionBlock. but use the pop/push methods

[self.navigationController popViewControllerAnimated:YES withCompletionBlock:NULL];
[self.navigationController pushViewController:vc animated:YES withCompletionBlock:^(BOOL successful) {
   NSLog(@"Hi ! Push done !");
}];
