從子視圖控制器推送視圖控制器

Question

我正在開發一個有容器視圖的應用程序，並試圖將其從父級推送到另一個視圖控制器中。 當我嘗試按下時，導航欄保持與父視圖控制器相同，而不是變成新按下的控制器的導航欄。 這是發生問題的動畫。 如何將導航欄更改為新的視圖控制器。 （在旁注中，鍵盤似乎也沒有關閉）

pushViewController將重用相同的導航控制器。 您可以執行presentViewController來呈現新的視圖控制器，也可以自己處理搜索欄的更改。 例如，在新的視圖控制器中將出現類似將搜索searchbar設置為隱藏/將navigationbar searchbar設置為其他樣式的操作。
