Resolution gesture ( UIPanGestureRecognizer and UIScreenEdgePanGestureRecognizer ) conflict
extension UIScrollView {
//当UIScrollView滑动手势与 UIScreenEdgePanGestureRecognizer手势同在,手势沿响应链向下传递
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWithGestureRecognizer otherGestureRecognizer: UIGestureRecognizer) -> Bool {
// 如果侧滑 Back 手势以及侧滑滚动手势同时响应,则调用 `open func require(toFail otherGestureRecognizer: UIGestureRecognizer)`使其侧滑滚动手势 failed
