问题 I've looked at several answers to questions similar but none of the answer worked. I have an app where I need everything portait except for one photo viewer I have. In the supported orientations section of the targets menu I only have portrait. How do I force my one view to be landscape. It is being pushed onto the stack from a nav controller but I'm using storyboards to control all that. 回答1: Since the answer seems to be hidden in the comments of the question and since ArunMak's answer is

Presenting modal in iOS 13 fullscreen

由 懵懂的女人 提交于 2019-11-27 05:15:35
In iOS 13 Beta 1 there is a new behaviour for modal view controller when being presented. Now it's not fullscreen by default and when I try to slide down, the app just dismiss the View Controller automatically. How can I prevent this behaviour and get back to the old good fullscreen modal vc? Thanks pascalbros With iOS 13, as stated in the Platforms State of the Union during the WWDC 2019, Apple introduced a new default card presentation. In order to force the fullscreen you have to specify it explicitly with: let vc = UIViewController() vc.modalPresentationStyle = .fullScreen self.present(vc,

I need to create singleton for a viewcontroller class. So I'm using this code create singleton class AViewController:UIViewController { static let sharedInstance = AViewController() required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) } } it gives me error

iOS - Linking framework storyboard to ViewController for use in main project

由 房东的猫 提交于 2019-11-26 21:41:02
问题 I am attempting to pull through and use a storyboard in my main project which is being created in a framework. This is to use the framework in a multitude of different projects going forward. I have managed, using a bundle, to feed the storyboard through to the main project and I can see it when I build the app. However the appending ViewController, also sitting within the framework, does not link during runtime. All the classes in the framework are being imported to the main project. The

In iOS, how to drag down to dismiss a modal?

由 僤鯓⒐⒋嵵緔 提交于 2019-11-26 21:09:37
A common way to dismiss a modal is to swipe down - How do we allows the user to drag the modal down, if it's far enough, the modal's dismissed, otherwise it animates back to the original position? For example, we can find this used on the Twitter app's photo views, or Snapchat's "discover" mode. Similar threads point out that we can use a UISwipeGestureRecognizer and [self dismissViewControllerAnimated...] to dismiss a modal VC when a user swipes down. But this only handles a single swipe, not letting the user drag the modal around. Robert Chen I just created a tutorial for interactively
