But the code I have been using to set this has now stopped working class func setLoginAsInitialViewContoller(window:UIWindow) { print("SET LOGIN") let storyboard = UIStoryboard(name: "Login", bundle: nil) let controller = storyboard.instantiateViewController(withIdentifier: "LoginViewController") controller

I've got a universal project here with storyboard. I've created a subclass of UIWindow called MyWindow, and I need to load it instead of the default UIWindow. Prior to storyboard, I would simply go to the .XIB file in XCode and change the class for the main window to MyWindow. However, I'm unable to find any section where I can change this in storyboard. Does anyone know where I can do this? I need the main window to load MyWindow, not UIWindow. When using storyboards the application delegate and main window are no longer represented in Interface Builder. Instead, when your app starts, your

I have an application, say 'MyApp', which by default loads the view controller 'MyAppViewController' whenever the application launches. Later, I added a new view controller 'NewViewControler' to the project. I now want the 'NewViewController' to be my default view controller which loads when the app launches. Please let me know what changes I need to make in my project to achieve this. Open MainWindow.xib and replace MyAppViewController with NewViewController. In your app delegate class, replace the property for MyAppViewController with one for NewViewController. Connect NewViewController to

问题 HI there, I'm trying to use UIScreen to drive a separate screen with the VGA dongle on my iPad. Here's what I've got in my root view controller's viewDidLoad: //Code to detect if an external display is connected to the iPad. NSLog(@"Number of screens: %d", [[UIScreen screens]count]); //Now, if there's an external screen, we need to find its modes, itereate through them and find the highest one. Once we have that mode, break out, and set the UIWindow. if([[UIScreen screens]count] > 1) //if
