56e41f4b71Sopenharmony_ci
57e41f4b71Sopenharmony_ciWhen this API is used, the navigation bar, including the title bar, content area, and toolbar, is hidden. In this case, if there is a navigation destination page in the navigation stack, the page at the top of the stack is displayed. Otherwise, a blank screen is displayed In versions earlier than API version 11, this API takes effect only in dual-column mode. Since API version 11, this API works for the single-column, dual-column, and adaptive modes. If a blank screen occurs due to the use of this API, you can remove this API or provide a navigation destination page in the navigation stack.
