To get a taste of everything just described, consider the following simple example where a button’s tap triggers the presentation of a sheet: The second is a closure, where we provide the view that will be displayed as the sheet’s content. In order to make the sheet appear, we change its value to true when necessary or after a user’s interaction.Ī sheet view modifier expects two arguments the first is the binding value of the property that controls its presented state. Initially we set it to false, indicating that way that the sheet must be hidden. Whether the sheet is presented or not is something we usually control with a boolean property declared locally in the view’s structure. Presenting a sheetĪ sheet in SwiftUI is available as a view modifier, which is usually applied to the outermost view object. Presenting sheets in SwiftUI is a fast and a no-brainer task, so read on to find out the few how-to guidelines that govern it. It constitutes a good solution in order to show additional information to users, ask for their input, or let them perform an operation without leaving entirely what they have been currently doing. A sheet is by default empty, and it’s our job as developers to provide it with custom views and content. Let ac = UIActivityViewController(activityItems: items, applicationActivities: )Īc.A sheet in iOS is a system provided view that appears modally on top of any other currently displayed view. If you wanted to use your view controller, first make it conform to UIActivityItemSource, like this: class ViewController: UIViewController, UIActivityItemSource This might be whatever view controller triggered the sharing, but ideally it would be a separate object. To fix this you need to make an object that conforms to the UIActivityItemSource protocol. If you start sharing some text and your users selects to share that using the Mail app, you’ll notice your text gets put into the body of the message with nothing in the subject. Give it the value “We need to write photos” then press return. So, open your project’s ist file, select any item, click +, then choose the key name “Privacy - Photo Library Additions Usage Description”. To fix this problem we need to add a text string describing our intent. As a result, if users try to tap that options your app will crash. That might seem fine, but writing to the photo library is a restricted operation.
However, the default share sheet for images will offer users the chance to save the image to their photo library.
You can share images as well, and the code is identical to other media: let items = You can combine items together just by extending the array: let items: = Sharing images
For example, If you select Twitter, both of those will work great, but if you select Facebook only the URL will be shared because Facebook doesn’t allow you to pre-enter text for users. The end result varies depending on which share service the user selects.
Let ac = UIActivityViewController(activityItems: items, applicationActivities: nil)Īnd you share URLs like this: let items = For example, you share text like this: let items = Let’s start with the basics: UIActivityViewController is the easiest way to let users share content like text and URLs.
