有没有办法创建一个带有下面描述的 url vCard 并使用 swift 4 共享它？... iOS 地图是否共享一个标记的位置

Question

我正在尝试通过 vCard 共享位置，如下所示：

var vCardString = [
    "BEGIN:VCARD",
    "VERSION:4.0",
    "N:;Shared Location;;;",
    "FN:Shared Location",
    "item1.URL:http://maps.apple.com/?ll=\(coordinate.latitude),\(coordinate.longitude)",
    "item1.X-ABLabel:map url",
    "END:VCARD"
    ].joined(separator: "\n")

let myData = vCardString.data(using: .utf8)! as NSData
var items = [Any]()
let vCardActivity = NSItemProvider(item: myData!, typeIdentifier: kUTTypeVCard as String)
items.append(vCardActivity)
let activityViewController = UIActivityViewController(activityItems: items, applicationActivities: nil)
present(activityViewController, animated:true, completion: nil)

这确实有效，但我无法在 vCard 下方添加描述...

我有这个

我在找这个

我试过添加另一个项目：

var items = [Any]()
let vCardActivity = NSItemProvider(item: myData!, typeIdentifier: kUTTypeVCard as String)
items.append(vCardActivity)
let myTitle = "This is my title"
items.append(myTitle)
let activityViewController = UIActivityViewController(activityItems: items, applicationActivities: nil)
present(activityViewController, animated:true, completion: nil)

但它只显示 vCard

非常感谢

如果向 VCard 添加地址字段会怎样？

像这样：

let vCardString = [
        "BEGIN:VCARD",
        "VERSION:4.0",
        "N:;Shared Location;;;",
        "FN:Shared Location",
        "ADR;TYPE=HOME;LABEL=42 Plantation St. Baytown, LA 30314 United States of America:;;42 Plantation St.;Baytown;LA;30314;United States of America",
        "item1.URL:http://maps.apple.com/?ll=25.686613,-100.316116",
        "item1.X-ABLabel:map url",
        "END:VCARD"
        ].joined(separator: "\n")

你会得到这样的东西：
