SloppySwiper is a UINavigationController delegate that allows swipe back gesture to be started from anywhere on the screen (not only from the left edge).

Note

• the library recreates the default pop animation, so it doesn't look exactly the same as when interactivePopGestureRecognizer is used:
  • cross dissolve animation is used in the navigation bar (instead of the back button movement)
  • the animation tends to be glitchy on the iOS Simulator, but it's fine on the device
  • hidesBottomBarWhenPushed isn't animated properly
• the gesture can collide with other pan to the right gestures
• If you're having problems with a UINavigationController inside of a UITabBarController that is causing the UITabBar to pop out of view during the animation process, you'll want to implement the SloppySwiperDelegate protocol and return NO for calls to -(BOOL)sloppySwiperShouldAnimateTabBar:(SloppySwiper *)swiper.

Usage

SloppySwiper can be set either in the Interface Builder or in code. The IB usage is presented in the example project (see Navigation Controller Scene in Main.storyboard). You can set it up programmatically as follows:

#import "SloppySwiper.h"
...
@property (strong, nonatomic) SloppySwiper *swiper;
...
self.swiper = [[SloppySwiper alloc] initWithNavigationController:navigationController];
navigationController.delegate = self.swiper;

Demo

To run the example project; clone the repo, and run pod install from the Example directory first. Alternatively, run pod try SloppySwiper from the command line.
