I am currently showing a viewController in my new storyboard below: var storyboard : UIStoryboard = UIStoryboard(name: AccountStoryboard, bundle: nil) var vc : WelcomeViewController = storyboard.instantiateViewControllerWithIdentifier("WelcomeID") as WelcomeViewController vc.teststring = "hello" self.presentViewController(vc, animated: true, completion: nil) However, this presents the viewcontroller without its embedded navigation controller. I tried changing "WelcomeID" to the navigation controller within the storyboard - however to no success. I got this working in Objective -C, however don

I'm relatively new in the XCode/iOS world; I've done some decent sized storyboard based apps, but I didn't ever cut me teeth on the whole nib/xib thing. I want to use the same tools for scenes to design/layout a reusable view/control. So I created my first ever xib for my view subclass and painted it up: I have my outlets connected and constraints setup, just like I'm used to doing in the storyboard. I set the class of my File Owner to that of my custom UIView subclass. So I assume I can instantiate this view subclass with some API, and it will configured/connected as shown. Now back in my

Want to give additional space from the top for navigation title shopping list. How can I do it? Dont see a option to do it in the properties of navigation item in the story board. Its close to the date, battery icon in the top of the app. Attached the screenshot. Tried the below code its not working using swift2 override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. navigationController?.navigationBar.setTitleVerticalPositionAdjustment(15,forBarMetrics: UIBarMetrics.Default) // set any number you want between -20 to 15 } Try

I am using Interface Builder and Storyboards to build my app. I am trying to connect my source code to my UIViewController in Storyboard, but none of my classes show up in the Custom Class dropdown menu. This is occurring in Xcode 11 beta 2 and Xcode 11 beta 4. I've tried some solutions in this Stack Overflow answer , but they are not working. I've already done all of the following: Relaunched Xcode Deleted derived data Reinstalled Xcode Tried a different Storyboard Recreated the UIViewController file Made a new project (the problem even occurred there) Typing the UIViewController name into

I've already read this and this questions. But I didn't understand why the code below is not enough. This just works. Do I need an else statement to set rootViewController for LoginViewController ? Isn't it already set by Storyboard? func application(application: UIApplication, willFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool { if Settings.loggedIn { let mainStoryboard = UIStoryboard(name: "Main", bundle: NSBundle.mainBundle()) let mainViewController = mainStoryboard.instantiateViewControllerWithIdentifier("MainViewController") self.window?.rootViewController =

Can a viewcontroller access the identifier of the segue that was used to transition to it? For example, I transition from viewcontroller A to viewcontroller B using a segue with the identifier "mySegue". Is there anyway for viewcontroller B to get the segue's identifier? I don't believe there is such a property. This kind of thing should be handled via the calling VC's prepareForSegue:sender method (as said in the comments) and then assigning a custom property to denote where it came from, etc. 来源： https://stackoverflow.com/questions/10629399/can-a-viewcontroller-access-the-identifier-of-an

I am using UIPageControl as indicator between different page (view controllers) of my application. In each of the view controllers, I need to have a different button on the left corner on the UIPageControl. If I place a UIButton at that position on each of the view controllers, I see it on the UIPageControl but the buttons do not respond to the touch event. Is there something I am missing? Or is there an alternative to do this? Thanks. I guess the page control and the view controller view are both subviews of the same view. In this case, the button is drawn outside of the view controllers view
