Question

My UIViewController calls a function on my rootViewController which then called popToRootViewControllerAnimated to return the view to the rootController. This all works - great!

不幸的是,UINavigationItem(顶端的托olbar)似乎对刚刚被拆除的根子“Controller”和“IDViewController”进行了 m弄。

What do I need to do? What have I done wrong?

Answer 1

航道并不记得对其作出的改动,因此,当你推举新的控制器时,导航条被改动,以赋予新的观察控制器名称,但它确实储存了以前的看法控制器所拥有的东西。

You will need to recreate the items in the toolbar each time you come back to the view controller that has custom items.

您可以在<条码>上填写:view WillAppear,而不是在<条码>上填写。我完全可以回顾一下,但你应当重新调整对导航工具禁运的海关控制,因为当一名新的观察控制员被推走时,这种控制不会得到维护。

Answer 2

It seems that calling popToRootViewController from the rootViewController messes things up. TO rectify this I called the following from within the calling UIViewController

[self.navigationController popViewControllerAnimated:YES];
