Swipe to go back only works on edge of screen?

My swipe to go back feature works but only works on the edge of the screen. How can I have it work from anywhere on the screen?

Solution

  • Apple says here :

    interactivePopGestureRecognizer

    The gesture recognizer responsible for popping the top view controller off the navigation stack. (read-only)

    @property(nonatomic, readonly) UIGestureRecognizer *interactivePopGestureRecognizer

    The navigation controller installs this gesture recognizer on its view and uses it to pop the topmost view controller off the navigation stack. You can use this property to retrieve the gesture recognizer and tie it to the behavior of other gesture recognizers in your user interface. When tying your gesture recognizers together, make sure they recognize their gestures simultaneously to ensure that your gesture recognizers are given a chance to handle the event.

    So SloppySwiper library customise the UIPanGestureRecognizer.

    Check out the library SloppySwiper, which achieves this by using UIPanGestureRecognizer and by recreating the default animation.

    SloppySwiper:- UINavigationController delegate that allows swipe back gesture to be started from anywhere on the screen like instagram.

    Usage of this library can be found here.

    Cocoapods:- pod "SloppySwiper"

    I test this library on ios7 and above. It works like a charm.
