Swift中的UIActivityViewController在iPad上崩溃 [英] UIActivityViewController in Swift Crashes on iPad

问题描述

我正在我的游戏中制作共享功能，我有代码，它在iPhone上工作正常但是当我在iPad上测试时，当我点击分享按钮时应用程序崩溃。我使用以下代码进行分享按钮

I am making a share function in my game and I have the code and it works fine on iPhone but when I test it on a iPad, when I tap the share button the app crashes. I am using the following code for the share button

let textToShare = "Check out this website!"

if let myWebsite = NSURL(string: "http://www.apple.com/") {
   let objectsToShare = [textToShare, myWebsite]
   let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
   self.view?.window?.rootViewController?.presentViewController(activityVC, animated: true, completion: nil)
}

推荐答案

在iPad上运行时，UIActivityViewController具有非null的popoverPresentationController属性。所以，请尝试以下。

The UIActivityViewController's has non-null popoverPresentationController property when running on iPad. So, try below.

if let wPPC = activityVC.popoverPresentationController {
    wPPC.sourceView = some view
    //  or
    wPPC.barButtonItem = some bar button item
}
presentViewController( activityVC, animated: true, completion: nil )
