ios - Swift 4 - 通过 UIActivityViewController 共享位置

Question

我正在尝试构建一个应用程序，我可以在其中共享地址并在任何导航应用程序(Google map 、Apple map 、waze 等)中打开它。 下面是我目前拥有的代码(在浏览了包括数十个 stackoverflow 问题在内的谷歌搜索结果页面之后)

@IBAction func navigeer(_ sender: Any) {
    var items = [AnyObject]()



    let latitude: Double = 52.033809
    let longitude: Double = 6.882286

    let locationTitle = "Navigate to this address"
    let URLString = "https://maps.apple.com?ll=\(latitude),\(longitude)"

    guard let cachesPathString = NSSearchPathForDirectoriesInDomains(.cachesDirectory, .userDomainMask, true).first else {
        print("Error: couldn't find the caches directory.")
        return
    }

    if let url = NSURL(string: URLString) {
        items.append(url)
    }

    let vCardString = [
        "BEGIN:VCARD",
        "VERSION:3.0",
        "N:;Shared Location;;;",
        "FN:Shared Location",
        "item1.URL;type=pref:http://maps.apple.com/?ll=\(latitude),\(longitude)",
        "item1.X-ABLabel:map url",
        "END:VCARD"
        ].joined(separator: "\n")

    let vCardFilePath = (cachesPathString as NSString).appendingPathComponent("vCard.loc.vcf")

    let nsVCardData = NSURL(fileURLWithPath: vCardFilePath)
    let shareItems:Array = [nsVCardData]

    let activityController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
    present(activityController, animated:true, completion: nil)
}

当我在我的模拟器上运行该应用程序时，我得到以下信息:

点击分享按钮后

为什么我没有收到 Apple map 或 Google map 等应用建议？我也不明白为什么它建议我将其复制到联系人中..

提前致谢。

使用 UIActivityViewController、Swift 5 共享位置

func activityItems(latitude: Double, longitude: Double) -> [AnyObject]? {
        var items = [AnyObject]()

        let URLString = "https://maps.apple.com?ll=\(latitude),\(longitude)"

        if let url = NSURL(string: URLString) {
            items.append(url)
        }

        let locationVCardString = [
            "BEGIN:VCARD",
            "VERSION:3.0",
            "PRODID:-//Joseph Duffy//Blog Post Example//EN",
            "N:;Shared Location;;;",
            "FN:Shared Location",
            "item1.URL;type=pref:\(URLString)",
            "item1.X-ABLabel:map url",
            "END:VCARD"
        ].joined(separator: "\n")

        guard let vCardData : NSSecureCoding = locationVCardString.data(using: .utf8) as NSSecureCoding? else {
            return nil
        }

        let vCardActivity = NSItemProvider(item: vCardData, typeIdentifier: kUTTypeVCard as String)

        items.append(vCardActivity)

        return items
    }

如何使用？

if let shareObject = self.activityItems(latitude: 52.033809, longitude: 6.882286) {
       //open UIActivityViewController 
}
