demo中push 没有Bar的控制器，右屏幕部分手势无反应

demo中点击 push a view controller without bar
打开的界面，右边屏幕，手势滑动无反应，这个只能这样吗？

Start by reproducing the behavior in the demo: push a view controller without a navigation bar, then try the right-side swipe gesture. Inspect the demo entry point and the fullscreen pop gesture implementation to determine whether the unresponsive region is expected or a bug. Done means the behavior is clarified and, if it is unintended, the affected gesture path is corrected.
