在 iphone ios 上的 swift 3 中弹出 [英] Popover in swift 3 on iphone ios

问题描述

我正在尝试使用以下代码制作弹出菜单:

I am trying to make a popover menu with the following code:

import UIKit

class BeobachtungViewController: UIViewController, UIPopoverPresentationControllerDelegate {


    @IBAction func addClicked(_ sender: AnyObject) {
        // get a reference to the view controller for the popover
        let popController = UIStoryboard(name: "Personenakte", bundle: nil).instantiateViewController(withIdentifier: "popoverId")

        // set the presentation style
        popController.modalPresentationStyle = UIModalPresentationStyle.popover

        // set up the popover presentation controller
        popController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.up
        popController.popoverPresentationController?.delegate = self
        popController.popoverPresentationController?.sourceView = sender as! UIView // button
        popController.popoverPresentationController?.sourceRect = sender.bounds

        // present the popover
        self.present(popController, animated: true, completion: nil)
    }

    // UIPopoverPresentationControllerDelegate method
    func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
        // Force popover style
        return UIModalPresentationStyle.none
    }
}

这适用于 iPad，但在 iPhone 上，弹出窗口会占据整个 iPhone 屏幕.我只想要一个带箭头的小窗户.我找到了几个教程，但没有一个对我有用.

This is working on iPad, but, on an iPhone, the popup takes the whole iPhone screen. I just want a small window with an arrow. I found several tutorials but none worked for me.

推荐答案

将您的委托方法更改为:

Change your delegate method to:

func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle {
    // return UIModalPresentationStyle.FullScreen
    return UIModalPresentationStyle.none
}
