SPInteractivePopNavigationController

SPInteractivePopNavigationController is navigation controller with an interactive transition which tries to mimic the default behavior of iOS 7.

Why?

On iOS 7, if you want a custom back button for your navigation controller, you must forget about the nice and out-of-the-box interactive gesture to pop the current view controller. There is a workaround to circumvent this:

self.navigationController.interactivePopGestureRecognizer.delegate = (id<UIGestureRecognizerDelegate>)self;

However, this may lead to some weird behavior of your app, including glitches and random crashes.

Therefore, the only way I found to preserve the original behavior while having custom back buttons is writing your own transition.

Features

• Works with custom back buttons.
• Works with navigation bar title text custom attributes.
• Transitions properly between view controllers with the navigation bar visible and invisible.

Limitations

• It requires that you apply some attributes to the navigation bar title text.
• It doesn't work with custom title views (yet…).

Install SPInteractivePopNavigationController

1. Using CocoaPods

Add SPInteractivePopNavigationController to your Podfile:

platform :ios, "7.0"
pod 'SPInteractivePopNavigationController'

Run the following command:

pod install

2. Manually

Clone the project or add it as a submodule. Drag the whole SPInteractivePopNavigationController folder to your project.

Then, you can simply do:

```objective-c
#import "SPInteractivePopNavigationController.h"
```

Usage of SPInteractivePopNavigationController

The easy way

Just use the SPInteractivePopNavigationController (directly or inheriting it) as your navigation controller:

SPMyViewController *myViewController = [[SPMyViewController alloc] init];

SPInteractivePopNavigationController *navigationController = [[SPInteractivePopNavigationController alloc] initWithRootViewController:myViewController];

The flexible way

You don't want to use SPInteractivePopNavigationController in your code? Don't worry, it's still easy: just wire SPPopAnimationController and SPHorizontalSwipeInteractionController with your navigation controller and view controllers. An example of this wiring can be found in the class SPInteractivePopNavigationController.
