Ios 模式VC未打开（Swift）

如何使VC也出现

我试过了，但ms加载干净，没有按钮和文本视图

let modalViewController = ClipboardViewController()
modalViewController.modalPresentationStyle = .overCurrentContext
present(modalViewController, animated: true, completion: nil)

示例：

正如您所期望的按钮等，我假设您已经在序列图像板或xib文件中设置了视图控制器。如果是这种情况，则不使用以下行创建它

让modalViewController=ClipboardViewController（）

，否则将在不设置任何控件的情况下创建一个控件（如您所见）。您需要从故事板/xib中实例化它，或者创建一个序列并执行该操作。

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    if indexPath.row == 0 {
        self.navigationController!.pushViewController(self.storyboard!.instantiateViewController(withIdentifier: "ViewController") as UIViewController, animated: true)
    } else if indexPath.row == 1 {
    // VC with animation
    } else if indexPath.row == 2 {
        self.navigationController!.pushViewController(self.storyboard!.instantiateViewController(withIdentifier: "Favorite") as UIViewController, animated: true)
    } else if indexPath.row == 3 {
        self.navigationController!.pushViewController(self.storyboard!.instantiateViewController(withIdentifier: "Settings") as UIViewController, animated: true)
    }
}

    let modalViewController = self.storyboard?.instantiateViewController(withIdentifier: "ClipboardViewController ID") as? ClipboardViewController
    modalViewController?.modalPresentationStyle = .overCurrentContext
    self.present(modalViewController!, animated: true, completion: nil)
