这是twitter的一些代码和平...我想知道如何像在iOS股票照片应用程序中一样获得共享操作视图...

@IBAction func twitterButton(sender: AnyObject) {
    
        let image: UIImage = UIImage(named: "LaunchScreenImage.png")!
        
        let twitterControl = SLComposeViewController(forServiceType: SLServiceTypeTwitter)
        twitterControl.setInitialText("")
        twitterControl.addImage(image)
        
        let completionHandler = {(result:SLComposeViewControllerResult) -> () in
            twitterControl.dismissViewControllerAnimated(true, completion: nil)
            switch(result){
            case SLComposeViewControllerResult.Cancelled:
                print("User canceled", terminator: "")
            case SLComposeViewControllerResult.Done:
                print("User tweeted", terminator: "")
            }
    }
        twitterControl.completionHandler = completionHandler
        self.presentViewController(twitterControl, animated: true, completion: nil)

}

    // Setting description
    let firstActivityItem = "Description you want.."

    // Setting url
    let secondActivityItem : NSURL = NSURL(string: "http://your-url.com/")!
    
    // If you want to use an image
    let image : UIImage = UIImage(named: "your-image-name")!
    let activityViewController : UIActivityViewController = UIActivityViewController(
        activityItems: [firstActivityItem, secondActivityItem, image], applicationActivities: nil)
    
    // This lines is for the popover you need to show in iPad
    activityViewController.popoverPresentationController?.sourceView = (sender as! UIButton)
    
    // This line remove the arrow of the popover to show in iPad
    activityViewController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.down
    activityViewController.popoverPresentationController?.sourceRect = CGRect(x: 150, y: 150, width: 0, height: 0)
    
    // Pre-configuring activity items
    activityViewController.activityItemsConfiguration = [
    UIActivity.ActivityType.message
    ] as? UIActivityItemsConfigurationReading
    
    // Anything you want to exclude
    activityViewController.excludedActivityTypes = [
        UIActivity.ActivityType.postToWeibo,
        UIActivity.ActivityType.print,

        UIActivity.ActivityType.postToFacebook

    activityViewController.isModalInPresentation = true
    self.present(activityViewController, animated: true, completion: nil)
