All UIViewControllers use the same UINavigationBar as child controllers of UINavigationControler. The setting of UIViewController determines the transition effect of UINavigationBar when pushing or poping. when one of the UIviewcontrollers sets the uinavigationbar to hidden , sometimes this transition effect is not so friendly.

YRNavigationBarPure hides the UINavigationBar through sendSubviewToBack:, and generates a screenshot of UINavigationbar for every UIViewController. When pushing or poping happens, the screenshot is added to the view of the UIViewController, so that each UIViewcontroller seems to have an independent UINavigationBar.

Two extended properties have been added for UIViewController. You need to complete the navigation bar's settings in viewDidLoad. You only need to focus on the navigation bar style of the current UIViewController without worrying about restoring settings. YRNavigationBarPure will manage all this.

yr_prefersNavigationBarHidden default is NO. Set this property to YES if your UIViewController needs to hide the navigation bar.

self.yr_prefersNavigationBarHidden = YES;

yr_interactivePopDisabled default is NO. Set this property to YES if your UIViewController needs to disable side sliding.

self.yr_interactivePopDisabled = YES;

UINavigationController has one extended a property

yr_allowFullScreenInteractivePop default is NO, set to YES if you need to turn on the full screen swiping back

self.yr_allowFullScreenInteractivePop = YES;
