iOS 10中的UIActivityViewController

有人知道如何在iOS 10中使用UIActivityView吗？由于某些原因，在Swift 3.0中，它将编译和构建，但当应用程序在按下共享按钮后运行时，使用以下代码会导致应用程序崩溃。。。它在iOS 9.3和Swift 2.0中运行得非常好

如代码行6的注释中所指定，或

将objectsToShare=[textToShare]设为！任何对象

都会导致Thread1：信号SIGABRT和应用程序崩溃

@IBOutlet weak var detailDescriptionLabel: UITextView!

@IBAction func share(_ sender: AnyObject) {
        let textToShare = detailDescriptionLabel.attributedText

        let objectsToShare = [textToShare] as! AnyObject
        // line above causes app crash in iOS 10 - compiled and built
        // error is "Thread1: signal SIGABRT"

        let activityVC = UIActivityViewController(activityItems: objectsToShare as! [AnyObject], applicationActivities: nil)

        activityVC.popoverPresentationController?.sourceView = (sender as! UIView)
        self.present(activityVC, animated: true, completion: nil)
    }


class ActivityForNotesViewController: UIActivityViewController {

    internal func _shouldExcludeActivityType(_ activity: UIActivity) -> Bool {
        let activityTypesToExclude = [
            //insert UIActivity here
        ]

        if let actType = activity.activityType {
            if activityTypesToExclude.contains(actType) {
                return true
            }
            else if super.excludedActivityTypes != nil {
                return super.excludedActivityTypes!.contains(actType)
            }
        }
        return false
    }
}

任何能帮我的人我都会很感激的

我想我可能已经回答了我自己的问题，但如果有人能再核实一下，我将不胜感激。代码中的注释是我为使此修复生效所做的各种更改。在iOS 10模拟器和真实设备中工作

@IBAction func share(_ sender: AnyObject) {
        // Changed attributedText to text!
        let textToShare = detailDescriptionLabel.text!

        // Removed Cast to AnyObject
        let objectsToShare = [textToShare]

        //Removed cast to AnyObject in the Function Call to get rid of error from removing it above
        let activityVC = UIActivityViewController(activityItems: objectsToShare , applicationActivities: nil)


//Moved cast for as! UIView outside the perantheses of sender so 
//that the as! can be used more efficiently. But most importantly
// I changed the as! to a as? instead thinking that might catch an error and it did... so this works.

        activityVC.popoverPresentationController?.sourceView = (sender) as? UIView
                self.present(activityVC, animated: true, completion: nil)
}

应该是使用它的方法。

为什么要将数组强制转换为任何对象。“这没什么意义。”安迪，我不太清楚为什么我最终真的这么做了。但出于某种原因，当我从代码中删除该文本时，编译器会抱怨。不进行强制转换是有意义的，而且效率更高，但我不知道没有强制转换如何工作。如果我不得不猜测，这可能是因为函数

UIActivityViewController（activityItems:

在这里使用强制转换来取消对函数的限制

objectsToShare as！[AnyObject]

let objectsToShare = [textToShare]

let activityVC = UIActivityViewController(activityItems: objectsToShare , applicationActivities: nil)
