如何使用Swift以编程方式在iOS中呈现popover？

我的目标是以编程方式将UIViewController呈现为popover

func clickButton() {
     //What should I do here?   


 }

正如您所看到的，转换样式设置为

交叉融合

，演示文稿设置为当前上下文中的

。因此，从技术上讲，如果我单击按钮，转换将起作用，我的目标是以编程方式进行转换

func clickButton() {
     //What should I do here?   


 }

如何在
单击按钮上以编程方式显示popover？
您可以尝试以下方法：

let rateViewController = RatePopupVC()
rateViewController.modalTransitionStyle = .crossDissolve
rateViewController.modalPresentationStyle = .overCurrentContext
self.present(rateViewController, animated: true, completion: nil)

如果要以编程方式关闭它

内硬聚氯乙烯

self.dismiss(animated: true, completion: nil)

您可以尝试以下方法：

let rateViewController = RatePopupVC()
rateViewController.modalTransitionStyle = .crossDissolve
rateViewController.modalPresentationStyle = .overCurrentContext
self.present(rateViewController, animated: true, completion: nil)

self.dismiss(animated: true, completion: nil)

试试这个：

func clickButton() {

    let vc : PopupVC = storyboard!.instantiateViewControllerWithIdentifier("PopupVCID") as! PopupVC
    vc.modalTransitionStyle   = UIModalTransitionStyleCrossDissolve;
    self.presentViewController(vc, animated: true, completion: nil)
}

试试这个：

func clickButton() {

    let vc : PopupVC = storyboard!.instantiateViewControllerWithIdentifier("PopupVCID") as! PopupVC
    vc.modalTransitionStyle   = UIModalTransitionStyleCrossDissolve;
    self.presentViewController(vc, animated: true, completion: nil)
}

如果您以模态方式呈现视图控制器。你可以这样做

func clickButton() {
    if let vc = self.storyboard?.instantiateViewController(withIdentifier:"YOUR_VIEW_CONTROLLER_ID") {
        vc.modalTransitionStyle   = .crossDissolve;
        vc.modalPresentationStyle = .overCurrentContext
        self.present(vc, animated: true, completion: nil)
    }
}

如果您以模态方式呈现视图控制器。你可以这样做

func clickButton() {
    if let vc = self.storyboard?.instantiateViewController(withIdentifier:"YOUR_VIEW_CONTROLLER_ID") {
        vc.modalTransitionStyle   = .crossDissolve;
        vc.modalPresentationStyle = .overCurrentContext
        self.present(vc, animated: true, completion: nil)
    }
}

试试下面的代码

let popupview = storyboard?.instantiateViewController(withIdentifier: "YourViewController")
popupview.view.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height)
self.addChildViewController(popupview)
self.view.addSubview(popupview.view)
popupview.didMove(toParentViewController: popupview)

试试下面的代码

let popupview = storyboard?.instantiateViewController(withIdentifier: "YourViewController")
popupview.view.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height)
self.addChildViewController(popupview)
self.view.addSubview(popupview.view)
popupview.didMove(toParentViewController: popupview)

所以你在故事板中定义了它，但想让它以编程方式查看？或者想编写代码并按编程方式查看它？也可以尝试以下方法之一：所以你在故事板中定义了它，但想让它按编程方式查看？或者想编写代码并通过编程方式将其推送到视图？也可以尝试以下方法之一：如何传递数据？它是
vc.profileImage
？如果我想在
PopViewController
本身的函数上传递数据怎么办？数据是
vc.profileImage
？如果我想在
PopViewController
本身的函数上传递数据，该怎么办
