If you have a SwiftUI application and you present text with a URL, have you notices how the URL is being opened by Safari and not an in-app browser, and want to change that?
What is OpenURLAction?
An action that opens a URL.
OpenURLAction can be used to create your own handler for opening url's in SwiftUI, this makes it possible to use your own (in-app) WebView or transform the url before you open it in a external browser.
OpenURLAction requires a return statement with an appropiate value, in the (psuedo) codeblock below you can see which results are possible and what their meaning is.
struct OpenURLAction.Result {
/// The handler did handle the URL.
let handled
/// The handler discarded the URL.
let discarded
/// The handler asks the system to open the original URL.
let systemAction
/// The handler asks the system to open the modified URL.
let systemAction(let URL)
}
Use Case: Simple url handler
requires you to have a function called handleURL()
/// Basic example
Text("Visit [my Blog](https://www.wesleydegroot.nl) for more details.")
.environment(\.openURL, OpenURLAction { url in
handleURL(url) // Define this method to take appropriate action.
return .handled
})
Use Case: Simple url handler
requires you to have a function called handleURL()
struct SafariURL: Identifiable {
let id = UUID()
let url: URL
}
struct ContentView: View {
@State
var safariURL: SafariURL?
var body: some View {
Text("Visit [my Blog](https://www.wesleydegroot.nl) for more details.")
.environment(\.openURL, OpenURLAction { url in
safariURL = SafariURL(url: url)
return .handled
})
.sheet(item: $safariURL, content: { safariURL in
SafariView(url: safariURL.url)
})
}
func handleURL(url: URL) {
/// open SFSafariViewController
}
}
Conclusion
OpenURLAction is a great way to handle URL's in SwiftUI, it allows you to create your own handler for URL's and decide what to do with them.
