Question

我尝试使用UIActivityView为我的应用创建共享按钮。当我按下应用程序中的按钮时出现错误。代码有什么问题？

@IBAction func shareButton(_ sender: UIButton) {

        let texttoshare = "Sharing"
        let URLtoshare = NSURL(string: "www.google.com")
        let objectsToShare:NSArray = [texttoshare, URLtoshare!]
        let activityVC = UIActivityViewController(activityItems: objectsToShare as! [Any], applicationActivities: nil)

        self.present(activityVC, animated: true, completion: nil)

            }
    }

错误：是线程1：信号SIGABRT

试试这个。至少，它没有错误地为我工作..

let texttoshare = "Sharing"
let URLtoshare = URL(string: "www.google.com")
let activityVC = UIActivityViewController(activityItems: [texttoshare, URLtoshare!], applicationActivities: nil)
self.present(activityVC, animated: true, completion: nil)

如果您想将UIActivityViewController用于iPad，则需要为popoverPresentationController?.sourceView指定activityVC。例如：

let texttoshare = "Sharing"
let URLtoshare = URL(string: "www.google.com")
let activityVC = UIActivityViewController(activityItems: [texttoshare, URLtoshare!], applicationActivities: nil)
activityVC.popoverPresentationController?.sourceView = button...
self.present(activityVC, animated: true, completion: nil)

UIActivityView按钮错误
