问题描述
我正在尝试制作一个弹出窗口,按下按钮即可显示。试图遵循我在谷歌发现的说明,但我的流行视图以全屏显示,其背景为黑色。
这是我的代码:
I'm trying to make a popup which will be presented by pressing a button. Tried to follow instructions which i found in google but my pop view presenting in a full screen and its background is black.Here is my code:
class ViewController: UIViewController, UIPopoverPresentationControllerDelegate {
@IBAction func someButtonPressed(sender: UIButton) {
let storyboard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let popupVC = storyboard.instantiateViewControllerWithIdentifier("hello") as! popupViewController
popupVC.modalPresentationStyle = .Popover
popupVC.preferredContentSize = CGSizeMake(300, 300)
let pVC = popupVC.popoverPresentationController
pVC?.permittedArrowDirections = .Any
pVC?.delegate = self
pVC?.sourceView = sender
pVC?.sourceRect = CGRect(x: 100, y: 100, width: 1, height: 1)
presentViewController(popupVC, animated: true, completion: nil)
}
}
我是什么'我做错了?
推荐答案
要使您的视图控制器显示为弹出窗口,您应该设置以下内容:
To make your view controller shown as a popup, you should set the following:
popupVC.modalPresentationStyle = .OverCurrentContext
popupVC.modalTransitionStyle = .CrossDissolve
您还应该设计视图控制器的位置,大小以使其看起来像弹出窗口。
You should also design your view controller's position, size to make it look like a popup.
这是我之前做的弹出窗口。
Here is my popup that i did before.
