推荐答案

我用下面的代码修改并找到了解决方案。

I modified with below code and found solution.

if (DeviceType.IS_IPAD == false)
{
    presentViewController(activityVC, animated: true, completion: nil)
}else {
    // Change Rect to position Popover
    let popUp = UIPopoverController(contentViewController: activityVC)
    popUp.presentPopoverFromRect(CGRectZero, inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
}
