ios - 如何使用 navBar 和自定义大小创建 modalVC？

Question

我需要创建具有自定义大小(例如:CGSize(width: 100, height: 100) 和坐标)的自定义 modalVC。 ModalVC 可能不像 popover(popover 有圆角)。

将有一个带有“完成”项的导航栏，用于关闭此 modalVC。

VC 会在其他 VC 中为 UIButton pressing 创建。

这是我的代码(由其他代码创建，仅存在弹出窗口):

class ViewController: UIViewController, UIPopoverPresentationControllerDelegate {
    @IBOutlet var button: UIButton!
    @IBAction func buttonPressed(sender: UIButton) {
        showModalVC()
    }

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    func showModalVC() {
        let modalVC = CustomModalViewController()
        modalVC.modalPresentationStyle = .popover
        if let modal = modalVC.popoverPresentationController {
            modal.delegate = self
            modal.sourceView = self.view
        }
        self.present(modalVC, animated: true, completion: nil)
    }
}

class CustomModalViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        self.preferredContentSize = CGSize(width: UIScreen.main.bounds.width,
                                           height: UIScreen.main.bounds.height/3)
    }
}

P.S: I know how to do this like PopOver, but not like custom modal.

试试这个

let VC = self.storyboard!.instantiateViewController(withIdentifier: "Identifier") as! YourViewController
let navController = UINavigationController(rootViewController: VC)
navController.preferredContentSize = CGSize(width: 500, height: 400)
navController.modalPresentationStyle = .formSheet
self.present(navController, animated:true, completion: nil)
