6/11/2023 0 Comments Swift share extension url![]() ![]() It will look like the following: Click +, And we will see following Prompt. That's more than enough theory for now, let me snow you how we can implement all of this using Swift 5. Select App or App Extension > signing & capabilities > Click + Add App Group. Oh, by the way each part can have it's own type and name, we'll use the Content-Disposition: form-data name="field1" line to let the server know about these fields, before we actually send the actual content value. The request method & URL is pretty straightforward, the interesting part is when you specify the Content-Type HTTP header, in our case the multipart/form-data boundary="xxx" value means, that we're going to send a request body using multiple parts and we're going to use the "xxx" boundary string as a separator between the parts. HTTP response = Status code + Headers + Body (response data).HTTP request = Method + URL + Headers + Body (request data).For example, you can get the contents of a local file URL as String by calling init (contentsOf:encoding:), or as a Data by calling init (contentsOf:options:). Most objects that read data from or write data to a file have methods that accept a URL instead of a pathname as the file reference. When users choose your Share extension, you display a view in which they compose their content and post it. Select some content, Control-click to reveal a contextual menu, and choose Share. Note Extensions can add new functionality to a type, but they can’t override existing functionality. URLs are the preferred way to refer to local files. View the Social area in Notification Center. For more details, see Protocol Extensions. In a nutshell, you send some data with some headers (think about it as a key-value user info object) to a given URL using a method and as a response you'll get back a status code, some headers and maybe some sort of response data too. In Swift, you can even extend a protocol to provide implementations of its requirements or add additional functionality that conforming types can take advantage of. To quickly summarize it first I'd like to tell you a few words about how the HTTP layer works. And you share URLs like this: let items URL(string: ' let ac UIActivityViewController(activityItems: items, applicationActivities: nil) present(ac, animated: true) The end result varies depending on which share service the user selects. ![]() Select the share extension template from the iOS pane and follow the steps in Xcode’s interface to add one to your app. Xcode presents a sheet that contains templates for different kinds of targets. Don't worry, it's just one link, about the multipart/form-data content type specification. To add a share extension to your app, open your app’s project in Xcode and select File > New > Target from the menu bar. I believe that you've already heard about the famous multipart-data upload technique that everyone loves to upload files and submit form data, but if not, hopefully this article will help you a little bit to understand these things better. ![]()
