ios - 仅在 swift 3 中的 whatsapp 上共享图像

Question

我只想在 whatsapp 上分享图片，但我使用的代码显示了其他在线分享平台，即 Messenger 和电子邮件。

我使用的代码:

    func share(shareText:String?,shareImage:UIImage?){

    var objectsToShare = [AnyObject]()

    if let shareTextObj = shareText{
        objectsToShare.append(shareTextObj as AnyObject)
    }

    if let shareImageObj = shareImage{
        objectsToShare.append(shareImageObj)
    }

    if shareText != nil || shareImage != nil{
        let activityViewController = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
        activityViewController.popoverPresentationController?.sourceView = self.view

        present(activityViewController, animated: true, completion: nil)
    }else{
        print("There is nothing to share")
    }
}

和分享

    let imageToShare = UIImage(named: "05")
    share(shareText: "", shareImage: imageToShare)

Answer 1

您无法隐藏 UIActivityViewController 中显示的所有选项，因为它取决于您共享的内容以及设备中安装的应用程序，但您可以像所有默认设置一样隐藏大部分选项这样的选项:

let activityController = UIActivityViewController(activityItems: sharingItems, applicationActivities: nil)

    activityController.excludedActivityTypes = [
        UIActivityType.assignToContact,
        UIActivityType.print,
        UIActivityType.addToReadingList,
        UIActivityType.saveToCameraRoll,
        UIActivityType.openInIBooks,
        UIActivityType(rawValue: "com.apple.reminders.RemindersEditorExtension"), 
        UIActivityType(rawValue: "com.apple.mobilenotes.SharingExtension"),
    ]

    present(activityController, animated: true, completion: nil)
