[英]Instantiate View controller with its tab bar from unlinked viewcontroller
[英]Pass from a child Viewcontroller (Tab) to a view controller
我有一個選項卡ViewController(A)和5個子視圖控制器(B),我想從我的一個子視圖控制器中傳遞到另一個我在情節提要(C)中的視圖控制器
我在子視圖控制器(B)中創建了一個按鈕,並通過按故事板中的按鈕將其鏈接到我的(C),但是單擊該按鈕后,我得到的是:

您應該將UINavigationControllers
添加為選項卡,並使用ViewControllers(B)作為這些導航控制器的根。 只有這樣,您才能執行push
。 否則,您必須使用模式顯示,該模式顯示將部分或全部覆蓋您的Tab欄控制器。
