分支未打开应用商店链接

我使用 Branch

private func createDeepLink(_ card: CardModel) -> (branchUniversalObject: BranchUniversalObject, branchLinkProperties: BranchLinkProperties) {
    let branchUniversalObject = BranchUniversalObject(canonicalIdentifier: ("cardId/\(card.id)"))
    branchUniversalObject.title = card.title
    branchUniversalObject.contentDescription = ""
    branchUniversalObject.imageUrl = card.photoURLsProperties.originalURL

    branchUniversalObject.addMetadataKey(CardKeys.cardID.rawValue, value: card.id)

    branchUniversalObject.addMetadataKey("placeAvatarURLString", value: card.photoURLsProperties.originalURL)

    branchUniversalObject.addMetadataKey("title", value: card.title)
    branchUniversalObject.addMetadataKey("isAutoGeneratedCard", value: "false")

    let fullLocationName = card.location.fullLocationName
    branchUniversalObject.addMetadataKey("fullLocationName", value: fullLocationName)

    branchUniversalObject.addMetadataKey(CardKeys.ownerID.rawValue, value: card.ownerID)
    branchUniversalObject.addMetadataKey(ParametersKeywords.type.rawValue, value: ModeKeywords.shareCard.rawValue)

    branchUniversalObject.addMetadataKey("availableSeats", value: card.peopleProperties.availableSeats.description)

    let coordinate = card.location.coordinate
    branchUniversalObject.addMetadataKey("latitude", value: coordinate.latitude.description)
    branchUniversalObject.addMetadataKey("longitude",value: coordinate.longitude.description)

    let linkProperties = BranchLinkProperties()
    linkProperties.feature = "sharing"
    linkProperties.addControlParam("$desktop_url", withValue: "http://www.appname.com")
    linkProperties.addControlParam("$ios_has_app_url", withValue: "appname://")
    linkProperties.addControlParam("$ios_url", withValue: "https://itunes.apple.com/app/idXXXXXXXXXXXXXXX")

    return (branchUniversalObject: branchUniversalObject, branchLinkProperties: linkProperties)
}

我的目标是,当点击深度链接时,如果安装了应用程序,则打开应用程序,如果没有,则打开应用程序商店链接。

更新1: 我这样修改了代码,只要点击链接,它就会打开应用商店,如果我使用3D Touch,那么我可以选择在哪里打开这个链接。如果安装了应用程序并单击链接立即打开应用程序(或者至少是浏览器中的一个链接,但有打开应用程序的选项),并且如果未安装应用程序,则单击链接,转到App Store App页面,是否可以这样做。

let linkProperties = BranchLinkProperties()
        linkProperties.feature = "sharing"
        linkProperties.addControlParam("$desktop_url", withValue: "http://www.appname.com")
        linkProperties.addControlParam("$ios_has_app_url", withValue: "https://appname.app.link/")
        linkProperties.addControlParam("$ios_url", withValue: "itms-apps://itunes.apple.com/app/idXXXXXX")
