Ios 在Swift中将共享操作添加到UIAlertController

我正在构建一个带有UIAlertController的应用程序，我希望有一个显示“共享”的按钮，然后打开类似

这似乎很容易做到，如果它不是一个子按钮

我的代码：

---

我的共享功能当前未定义。

如果您的

共享方法不起作用，请执行类似操作

ac.addAction(UIAlertAction(title: "Share", style: .Default, handler: { (action) -> Void in 
    // Do the Facebook sharing here
    let content = FBSDKSharePhotoContent()
    content.photo = ....
    ....
}))

您可以在完成处理程序中定义在点击
UIAlertAction
后打开
UIActivityController
，但是默认情况下，iPhone中的Apple不会在iPad中显示您想要的共享，是的。点击按钮后，您可以使用以下代码显示共享：

let message = "The message"
let alertController = UIAlertController(title: "The title", message: message, preferredStyle: .Alert)

let shareAction = UIAlertAction(title: "Share", style: .Default, handler: { x -> Void in

     let firstActivityItem = "Text you want"
     let secondActivityItem : NSURL = NSURL(string: "http//:urlyouwant")!

     // If you want to put an image
     let image : UIImage = UIImage(named: "image.jpg")!

     let activityViewController : UIActivityViewController = UIActivityViewController(
                activityItems: [firstActivityItem, secondActivityItem, image], applicationActivities: nil)

     // Anything you want to exclude
     activityViewController.excludedActivityTypes = [
           UIActivityTypePostToWeibo,
           UIActivityTypePrint,
           UIActivityTypeAssignToContact,
           UIActivityTypeSaveToCameraRoll,
           UIActivityTypeAddToReadingList,
           UIActivityTypePostToFlickr,
           UIActivityTypePostToVimeo,
           UIActivityTypePostToTencentWeibo
      ]

      self.presentViewController(activityViewController, animated: true, completion: nil)
 })

alertController.addAction(shareAction)
self.presentViewController(alertController, animated: true, completion: nil)

在上面的代码中，我总结了“添加更多”按钮，我假设您想要iPhone的代码，如果您也想要iPad的代码，您可以在以下问题中查看我的答案：





我希望这对你有帮助
 这里有一个答案：
我将股份类别定义为：

func共享（操作：UIAlertAction！）{

你在哪里定义你的共享操作的完成处理程序？我明白了。我理解你为什么有点困惑。这只是一个例子，我只想输入一些预填充的文本。不知道你到底想要什么。如何使用Facebook API？或者只是将共享按钮操作与弹出窗口链接？或者实际构建你的应用程序弹出视图？
let message = "The message"
let alertController = UIAlertController(title: "The title", message: message, preferredStyle: .Alert)

let shareAction = UIAlertAction(title: "Share", style: .Default, handler: { x -> Void in

     let firstActivityItem = "Text you want"
     let secondActivityItem : NSURL = NSURL(string: "http//:urlyouwant")!

     // If you want to put an image
     let image : UIImage = UIImage(named: "image.jpg")!

     let activityViewController : UIActivityViewController = UIActivityViewController(
                activityItems: [firstActivityItem, secondActivityItem, image], applicationActivities: nil)

     // Anything you want to exclude
     activityViewController.excludedActivityTypes = [
           UIActivityTypePostToWeibo,
           UIActivityTypePrint,
           UIActivityTypeAssignToContact,
           UIActivityTypeSaveToCameraRoll,
           UIActivityTypeAddToReadingList,
           UIActivityTypePostToFlickr,
           UIActivityTypePostToVimeo,
           UIActivityTypePostToTencentWeibo
      ]

      self.presentViewController(activityViewController, animated: true, completion: nil)
 })

alertController.addAction(shareAction)
self.presentViewController(alertController, animated: true, completion: nil)

    if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) {
        let facebook:SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
        facebook.setInitialText("I just scored \(score) in Flagpoles.")

        self.presentViewController(facebook, animated: true, completion: nil)

        score = 0

    } else {
        let alert = UIAlertController(title: "Accounts", message: "Please login to a Facebook account to share.", preferredStyle: UIAlertControllerStyle.Alert)

        alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
        self.presentViewController(alert, animated: true, completion: nil)
    }
