My need is to use ShareLink to allow the user to send formatted email or text message including a URL link. My SwiftUI code looks like:
ShareLink(
item: itemText,
subject: Text("Message from app user"),
preview: SharePreview("Link",image: "AppIcon")) {
Label(message, systemImage: "square.and.arrow.up")
}
where I'm generating itemText from itemText(link: URL) (I've trimmed the string I'm using to just the basics):
func shareItemMessage(link: URL) -> String {
return
"Please join me on our app\n\n"
+ "Tap on [link](\(link)) to accept my invitation (link: \(link)).\n\n"
}
func itemText(link: URL) -> (some Transferable)? {
// The `available` condition is needed because only in iOS 16.1 does AttributedString conform to Transferable.
if #available(iOS 16.1, *) {
// The AttributedString options below enable inclusion of whitespace in the text formatting.
// See also https://forums.macrumors.com/threads/markdown-linebreaks-are-ignored.2367417/
return try? AttributedString(markdown: shareItemMessage(link: link),
options: AttributedString.MarkdownParsingOptions(
allowsExtendedAttributes: false,
interpretedSyntax: .inlineOnlyPreservingWhitespace,
failurePolicy: .returnPartiallyParsedIfPossible,
languageCode: nil
))
} else {
return shareItemMessage(link: link)
}
}
My problem is that the markdown gets stripped out when the user chooses the message app. Example:
And when they use an email, I get two links. Example:
Note that I've generated the image examples above running on an iPhone with > iOS 16.1, so it's using the AttributedString formatting for both the message and email.
Has anyone come up with a better way to do this? i.e., to use ShareLink to send a text email or message with a link?
