Support gesture back to previous controller after hiding navigation bar

Support gesture back to previous controller after hiding navigation bar

Description

1. After we hide the navigation bar, the gesture bounce disappears, but you can continue to support gestures by some means

2. Pay special attention when using the root controller of the navigation bar controller, which causes bugs to appear, but can be resolved by disabling gestures

3. For custom-made people, you must use your own navigation bar view, because the system has a gray line above the navigation bar can not be removed.

Set up
