使用UIImageView分享UIActivityViewController的图片？

我正在尝试使用UIActivityViewController分享图片，但收到错误：

func shareIMG(){
    let activityItems = [self.imageView.image]
    let avc = UIActivityViewController(activityItems: activityItems, applicationActivities: nil)

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

错误讯息：

找不到类型为'UIActivityViewController'的初始值设定项接受类型'的参数列表'（activityItems：[UIImage？]， applicationActivities：nil）'

有什么想法吗？

Answer 1

let activityItem: [AnyObject] = [self.imageView.image as! AnyObject]

    let avc = UIActivityViewController(activityItems: activityItem as [AnyObject], applicationActivities: nil)

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

注意：以上代码在Xcode 6.3模拟器中进行了测试

Answer 2

只需创建一个按钮及其动作即可。然后像这样安装按钮的动作。

注意：您必须通过设置登录您的Facebook或Twitter。然后这样做。

@IBAction func onShareTouched(sender: AnyObject) {

    print("share")

    let myShare = "My beautiful photo! <3 <3"
    let image: UIImage = UIImage(named: "yourImageNameHere")

    let shareVC: UIActivityViewController = UIActivityViewController(activityItems: [(image), myShare], applicationActivities: nil)
    self.presentViewController(shareVC, animated: true, completion: nil)

  }

适用于Swift的iPhone和iPad的完整代码：

func share(sender: UIButton){
    let img: UIImage = UIImage(named: "lenna")!
    let messageStr:String  = "some sharing text"
    let shareItems:Array = [img, messageStr]

    activityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
    activityViewController!.excludedActivityTypes = [UIActivityTypePrint, UIActivityTypePostToWeibo, UIActivityTypeCopyToPasteboard, UIActivityTypeAddToReadingList, UIActivityTypePostToVimeo]

    if UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.Phone {
        self.presentViewController(activityViewController!, animated: true, completion: nil)
    } else {
        let popup: UIPopoverController = UIPopoverController(contentViewController: activityViewController!)
        popup.presentPopoverFromRect(sender.bounds, inView: sender, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
    }
}
