Question

我有一个简单的应用程序，我在其中运行一些GET查询并在完成后触发模态视图。呈现视图控制器包含带有搜索控制器/搜索栏的地图视图。当触发模态时，它会按预期显示overCurrentContext（带有模糊效果），但导航栏（带有取消按钮）会在搜索栏下方滑动。我可以看到导航栏已正确创建（带有标题和取消按钮），但它会在搜索栏下方转换。我做错了什么吗？

呈现viewController

func showPopOver()  {
    let fares = Fares(userLocation: userLocation, destination: userDestination)
    fares.getFares { _ in
        self.RideCosts = self.storyboard!.instantiateViewController(withIdentifier: "RideCosts") as! RideCosts
        self.RideCosts.modalPresentationStyle = .overCurrentContext
        self.RideCosts.loadFares(fares: fares.fareArray)
        self.present(self.RideCosts, animated: true, completion: nil)
     }
}

modalViewController（RideCosts）

class RideCosts: UIViewController, UITableViewDelegate, UITableViewDataSource {

    @IBOutlet weak var tableView: UITableView!
    @IBAction func cancel(_ sender: UIBarButtonItem) {
        dismiss(animated: true, completion: nil)
    }

    var fareArray: [(name: String, value: String)] = []
    var arrayOfCellData = [cellData]()

    override func viewDidLoad() {
        super.viewDidLoad()
        let blurEffect = UIBlurEffect(style: .extraLight)
        let blurEffectView = UIVisualEffectView(effect: blurEffect)
        blurEffectView.frame = self.view.frame
        self.view.insertSubview(blurEffectView, at: 0)

        self.view.backgroundColor = UIColor.clear
        self.modalTransitionStyle = .crossDissolve
        self.isModalInPopover = true

        tableView.delegate = self
        tableView.dataSource = self
   }

回到这个...... Swift菜鸟错误，我通过将modalpresentationStyle设置为overFullScreen而不是overCurrentContext

解决了模态演示（模式视图＆在搜索栏下方显示的导航栏）的问题

工作代码

func showPopOver()  {
let fares = Fares(userLocation: userLocation, destination: userDestination)
fares.getFares { _ in
    self.RideCosts = self.storyboard!.instantiateViewController(withIdentifier: "RideCosts") as! RideCosts
    self.RideCosts.modalPresentationStyle = .overCurrentContext  //FIX
    self.RideCosts.loadFares(fares: fares.fareArray)
    self.present(self.RideCosts, animated: true, completion: nil)
 }

}

模态视图导航栏无法正确显示
