I have an app with tab bar controller (with 4 views controller) and it contains a navigation controller. All of this was create programmatically. My question: Is there a way how to set one navigation bar title for all view controllers ? For example: When i switch tabs, title is the same. Ideal solution for me is set title in app delegate file. Thanks a lot

推荐答案

如果你知道会有 4 个视图控制器，那就做 self.title = @"your title"; 如果你想要更改您的标题"一次并将它们全部更改，只需创建一个静态全局或使用 plist.并将代码放在 viewDidAppear 下，以便每次刷新.不需要做任何太复杂的事情:)

If you know that there will be exactly 4 views controller, just do self.title = @"your title"; If you want to change "your title" once and have them all changed, just create a static global or use plist. And put the code under viewDidAppear so that it refreshes every time. No need to do anything too complex :)
