uinavigationcontroller

问题 For a navigation controller I like to have a few controls placed in a view from top towards the bottom. I am using auto layout and added constraints, so that the views have a vertical gap to each other. This looks nice for iOS7 and iOS6 in a normal view controller, also for iOS7 in a navigation controller; but wrong in iOS6. The UISegmentedControl shows up wrong. See the screenshots. It looks like the larger height of the UISegmentedControl is not taken into account for iOS6 view. Also it

问题 I have an iPhone app using a UINavigationController. On the fourth controller of the stack, I'm doing some Core Location stuff - so, the first couples of times that the user uses my app, they are asked if it's ok to use Location Services. This is a process that (I think) I don't have any control over. After the user confirms, they are actually bumped back to my root view controller in the navigation controller stack. Is this a bug, am I doing something wrong, or is this expected behavior? I

NSLog(@"%p", self); NSLog(@"1st Controller"); [self.navigationController setNavigationBarHidden:YES animated:YES]; dispatch

问题 I've got two storyboards. I found some code on how I can instantiate the initial View Controller of another Storyboard and move (or do you say segue?) to that. But those examples used a Navigation Controller. The user shouldn't be able to go back to the previous Storyboard in my case (login page). The app can forget about the old Storyboard, it's not needed ever again when I move over to the new one. So the View Controller on top of the hierarchy in the first Storybard can be forgotten about,

问题 I'm building a project using Xcode 4.2 and I'm also using the Storyboard. So basically, I have a UINavigationcontroller which is my initial view, connected to my "Main Menu" view. Inside my "Main Menu" I have a button that is linked to a tabbar controller, which has like 20 tabs. Therefore, a "More" button appears and when the "more" button is clicked an "edit" button appears. Everything works fine, but the only problem I have is that once I click edit, the configure page slides up and the

问题 I want to use my custom UINavigationController and UITabbar for my app it is possible? 回答1: Ofcourse it is possible to make custom navigationController with UITabbar.Though i suggest you to take a navigation based application and a Tabbar in it.
