这是我的代码到目前为止，但我得到一个错误，UIBarButtonItem不能为UIVIew服务为什么？该操作是否连接到导航栏按钮项？

Here is my code so far, but i get an error that UIBarButtonItem Is not convetable to UIVIew Why? The action is connected to a navigation bar button item?

@IBAction func ActionButton(sender: UIBarButtonItem) {

    let firstActivityItem = "Text you want"
    let secondActivityItem : NSURL = NSURL(string: "http//:urlyouwant")!
    // If you want to put an image
    let image : UIImage = UIImage(named: "TALogo")!

    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! UIBarButtonItem)

    // This line remove the arrow of the popover to show in iPad
    activityViewController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.allZeros
    activityViewController.popoverPresentationController?.sourceRect = CGRect(x: 150, y: 150, width: 0, height: 0)

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

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



}

推荐答案

方式是使用 UIActivityViewController ，例如通过以下方式：

The way is using UIActivityViewController for example in the following way :

@IBAction func shareSheet(sender: AnyObject) {

    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)

    // 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.allZeros
    activityViewController.popoverPresentationController?.sourceRect = CGRect(x: 150, y: 150, width: 0, height: 0)

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

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

以上代码适用于iPhone和iPad，因为你设置了新的 iOS 8中的popoverPresentationController 也适用于iPad。

The above code works for both iPhone and iPad because in you set the new popoverPresentationController in iOS 8 it works for iPad too.

如果使用 UIBarButtonItem 你需要替换这一行：

In the case of use an UIBarButtonItem you need to replace this line:

activityViewController.popoverPresentationController?.sourceView = (sender as! UIButton)

这一个：

activityViewController.popoverPresentationController?.barButtonItem = (sender as! UIBarButtonItem)

我希望这能帮到你。
