记录一下 以备以后用到的时候拿出来看看。
以前使用的：
1 if (UIDevice.currentDevice().userInterfaceIdiom == UIUserInterfaceIdiom.Phone) {
2 presentViewController(vc, animated: true, completion: nil)
3 } else if (popover == nil || !popover!.popoverVisible) {
4 popover = UIPopoverController(contentViewController: vc)
5 popover!.delegate = self popover?.presentPopoverFromRect(inviteView.frame, inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
现在使用：
if #available(iOS 8.0, *) {
vc.modalPresentationStyle = UIModalPresentationStyle.Popover
vc.popoverPresentationController?.sourceView = inviteView
vc.popoverPresentationController?.sourceRect = inviteView.bounds
vc.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.Any
presentViewController(vc, animated: true, completion: nil)
} else {
//DeviceUtils.isIOS7()
if (UIDevice.currentDevice().userInterfaceIdiom == UIUserInterfaceIdiom.Phone) {
presentViewController(vc, animated: true, completion: nil)
} else if (popover == nil || !popover!.popoverVisible) {
popover = UIPopoverController(contentViewController: vc)
popover!.delegate = self
popover?.presentPopoverFromRect(inviteView.frame, inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
}
// Fallback on earlier versions
}
