UIActivityController未在屏幕上全屏显示

Question

我正在演示UIActivityController，但它只在屏幕上显示了一半。

​

 let textToShare = "This is awesome!  Check out this website about it!"
    if let myWebsite = NSURL(string:urlShare) {
        let objectsToShare = [textToShare, myWebsite]
        let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
        //New Excluded Activities Code
        activityVC.excludedActivityTypes = [UIActivityTypeAirDrop, UIActivityTypeAddToReadingList]

        self.navigationController!.presentViewController(activityVC, animated: true, completion: nil)

Answer 1

您是否尝试在当前的ViewController上而不是在self.navigationController上执行self.presentViewController。

我过去经常遇到这个问题，因为我的rootViewController比较大，因此当使用self.navigationController演示时，它会被切断。

Answer 2

尝试在POP UPViewController中添加

var popup = UIPopoverController(contentViewController: controller)
popup.presentPopoverFromRect(CGRectMake(self.view!.frame.size.width / 2, self.view!.frame.size.height / 4, 0, 0), inView: self.view!, permittedArrowDirections: .Any, animated: true)

在这里，控制器是您的activityVC
