标记 didtap 无法将数据传递给视图控制器

Question

当我在点击视图上的标记弹出一个视图控制器以显示标记的详细信息时。 但现在我面临的问题是数据没有传递给视图控制器。 我正在使用 for 循环来循环我的标记。

这是我的谷歌地图视图控制器：

class locationViewController: UIViewController, GMSMapViewDelegate {

@IBOutlet weak var googleMapView: UIView!

@IBOutlet weak var menuView: UIView!

var mapView:GMSMapView?
var popUptitle : String?
var popupaddress : String?
var popuptime : String?
var popupphone : String?

struct State {
    let name: String
    let long: CLLocationDegrees
    let lat: CLLocationDegrees
    let phone : String
    let address : String
    let time : String
}

override func viewDidLoad() {

    super.viewDidLoad()


    let A = GMSCameraPosition.camera(withLatitude: 2.1898683, longitude: 102.2464156, zoom: 13)
    mapView = GMSMapView.map(withFrame:self.view.bounds, camera: A)
    mapView?.delegate = self

    let states = [
        State(name: "A", long: 102.2464156, lat: 2.1898683,phone: "1234", address: "A Address",time:"11AM - 10PM"),
        State(name: "B", long: 102.249949, lat: 2.189052,phone: "Tel No: 5678", address: "B Address",time:"11AM - 10PM"),
        State(name: "C", long: 102.252837, lat: 2.205183,phone: "Tel No: 9012", address: "C Address",time:"11AM - 10PM")

    ]
    for state in states {
        let markerPosition = CLLocationCoordinate2DMake(state.lat, state.long)
        let marker = GMSMarker(position:markerPosition)
        marker.icon = UIImage(named: "custom_marker")
        marker.map = mapView
        popUptitle = state.name
        popupaddress = state.address
        popupphone = state.phone
        popuptime = state.time
    }

    self.googleMapView.addSubview(mapView!)
    self.mapView?.addSubview(menuView)
    menuView.isHidden = true
    }

func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
    let popup = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "marker_popup") as! MarkerPopupViewController
    self.addChildViewController(popup)
    popup.view.frame =  self.view.bounds
    self.view.addSubview(popup.view)
    popup.didMove(toParentViewController: self)
    popup.marker_name = popUptitle
    popup.marker_address = popupaddress
    popup.marker_time = popuptime
    popup.marker_pn = popupphone
    return true
}

这是我的自定义信息窗口视图控制器

import UIKit

class MarkerPopupViewController: UIViewController {

var marker_name : String?
var marker_address : String?
var marker_time : String?
var marker_pn : String?

@IBOutlet weak var outlet_pn: UILabel!
@IBOutlet weak var outlet_time: UILabel!
@IBOutlet weak var outlet_address: UILabel!
@IBOutlet weak var outlet_name: UILabel!
@IBOutlet weak var outlet_img: UIImageView!
override func viewDidLoad() {
    super.viewDidLoad()
    self.outlet_name.text = marker_name
    self.outlet_time.text = marker_time
    self.outlet_address.text = marker_address
    self.outlet_pn.text = marker_pn
    self.outlet_address.sizeToFit()
}
@IBAction func marker_close(_ sender: Any) {
    self.view.removeFromSuperview()
}

@IBAction func callBtn(_ sender: Any) {
}
@IBAction func directionBtn(_ sender: Any) {
}


}

将行的顺序改为

func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
    let popup = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "marker_popup") as! MarkerPopupViewController
    popup.marker_name = popUptitle
    popup.marker_address = popupaddress
    popup.marker_time = popuptime
    popup.marker_pn = popupphone
    popup.view.frame =  self.view.bounds
    self.addChildViewController(popup)
    self.view.addSubview(popup.view)
    popup.didMove(toParentViewController: self)
    return true
}
