问题 I am using a UITabBarController as well as a UINavigationController on my app. In my UITabBarController I am using more than 5 items so I automatically get the 'More' item. I've managed to add a saving procedure so the order of those items will be kept in case somebody changes the order etc. With 'More' active I get the More navigation controller with the 'Edit' item positioned under my UINavigationController. Both navigation controller are visible. When I click on 'Edit though the More

问题 I'm trying to edit the tile of the back item in the navigation controller. I have this scene, Navigation Controller -> Table View Controller -> TableViewController . In the second TableViewController I want to rename the the back item from " xxxx " to " Back ". Is there a way to do via the StoryBoard , or should I do it programmatically ? This is what I've tried but it does not work: let backItem = UIBarButtonItem() backItem.title = "Back" navigationItem.backBarButtonItem? = backItem or

问题 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 回答1: If you know that there will be exactly 4 views controller, just do self.title = @"your title"; If you want to change "your title"

In other words detecting a backwards navigation within the source view controller. In contrast,

问题 I'm trying to position the navigation bar below the top of the screen. I've tried the following in viewWillAppear : self.navigationController.view.frame = CGRectMake(0.0, 54.0, 320.0, 426.0); self.navigationController.navigationBar.frame = CGRectMake(0.0, 0.0, 320.0, 44.0); The problem is it only seems to work the very first time the view is displayed. If you go to another tab, and back, the navigation bar is at the top of the screen. This also happens when the iPhone is rotated. Should I be

问题 After I search a lot of questions and answers, no good result. So I have to ask it here: I want to add a Search Bar below the navigation bar. This search bar should be fixed. Just like contacts on iOS7 below. Can any one help me to figure it out? 回答1: You have a view controller. It has a main view. Inside that main view is a search bar (UISearchBar) and, below that, a table view (UITableView). Your view controller is embedded in a navigation controller (UINavigationController).
