Swift:iOS - 将数据从 ViewController 传递到 xib 文件，直到 3rd 类

Question

我有一个非常具体的问题，我希望有人可以帮助我解决这个问题。我有以下文件，实际上只是一个locationXIB连接到xib的文件，我将其显示为自定义MKAnnotation标注：

class locationXIB: UIView {
@IBOutlet weak var loationLabel: UILabel!
@IBOutlet weak var oteviraciDobaLabel: UILabel!
@IBOutlet weak var prijmajiKartyLabel: UILabel!
@IBOutlet weak var souradniceLabel: UILabel!
var customAnnotationsArray = [VecerkaAnnotation]()
override func awakeFromNib() {
super.awakeFromNib()
}
}

在此场景中发挥作用的第二个类是一个名为VecerkaAnnotation的类，它是注释本身：

import Foundation
import MapKit
class VecerkaAnnotation: NSObject, MKAnnotation {
var myCoordinate: CLLocationCoordinate2D
var prijmajiKarty = true
var vsedniOteviraciDoba = ""
var vikendovaOteviraceDobra = ""
init(myCoordinate: CLLocationCoordinate2D){
self.myCoordinate = myCoordinate
}
var coordinate: CLLocationCoordinate2D {
return myCoordinate
}
}

第三类(为简单起见进行了剥离(是我的MapViewController，这是从Google Firestore获取文档并创建类型[VecerkaAnnotation]数组的代码块：

class MapViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {
var customAnnotationsArray = [VecerkaAnnotation]()
:
:
func fetchDocuments() {
let vecerkyRef = db.collection("vecerkyInfo")
Prog.start(in: mapView, .blur(.dark), .activityIndicator)
vecerkyRef.getDocuments { (querySnapshot, err) in
Prog.dismiss(in: self.mapView)
if let err = err {
print("Error fetching data from Firestore: (err)")
let alert = UIAlertController(title: "Error fetching data", message: "Data could not be fetched, make sure you're connected to the Internet", preferredStyle: .alert)
let action = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
alert.addAction(action)
self.present(alert, animated: true)
} else {
for document in querySnapshot!.documents {
if let coords = document.get("geopoint"), let vsedni = document.get("vsedni"), let vikend = document.get("vikend"), let prijmajKarty = document.get("karty"){
let point = coords as! GeoPoint
let lat = point.latitude
let lon = point.longitude
let coord = CLLocationCoordinate2D(latitude: lat, longitude: lon)
let newAnnotation = VecerkaAnnotation(myCoordinate: coord)
newAnnotation.vikendovaOteviraceDobra = vikend as! String
newAnnotation.vsedniOteviraciDoba = vsedni as! String
newAnnotation.prijmajiKarty = prijmajKarty as! Bool
self.customAnnotationsArray.append(newAnnotation)
}
self.createAnnotations()
}
self.setLocation()
}
}
}

第四类也是最后一类是负责管理MKAnnotationView的类

class LocationInformationAnnotationView: MKAnnotationView {
weak var customCalloutView : locationXIB?
:
:
func loadLocationInformationCalloutView() -> locationXIB? {
if let views = Bundle.main.loadNibNamed("locationXIB", owner: self, options: nil) as? [locationXIB], views.count > 0 {
let locationInformationCalloutView = views.first!
return locationInformationCalloutView
}
return nil
}
override func setSelected(_ selected: Bool, animated: Bool) {
if selected {
self.customCalloutView?.removeFromSuperview()
if let newCustomCalloutView = loadLocationInformationCalloutView() {
newCustomCalloutView.frame.origin.x -= newCustomCalloutView.frame.width / 2.0 - (self.frame.width / 2.0)
newCustomCalloutView.frame.origin.y -= newCustomCalloutView.frame.height
self.addSubview(newCustomCalloutView)
self.customCalloutView = newCustomCalloutView
if animated {
self.customCalloutView!.alpha = 0.0
UIView.animate(withDuration: 0.5, animations: {
self.customCalloutView!.alpha = 0.9
self.customCalloutView!.layer.shadowColor = UIColor.black.cgColor
self.customCalloutView!.layer.shadowOffset = CGSize(width: 0, height: 5)
self.customCalloutView!.layer.shadowRadius = 8
self.customCalloutView!.layer.shadowOpacity = 0.2
self.customCalloutView!.layer.cornerRadius = 5
})
}
}
} else {
if customCalloutView != nil {
if animated {
UIView.animate(withDuration: 0.5, animations: {
self.customCalloutView!.alpha = 0.0
}, completion: { (success) in
self.customCalloutView!.removeFromSuperview()
})
} else { self.customCalloutView!.removeFromSuperview() }
}
}
}

我在这里要实现的是，让标签locationXIB由从Google Firestore检索到的VecerkaAnnotation的属性填充。我已经尝试了很多方法，但很绝望。感谢任何和所有的帮助，谢谢！.

目前，我已经通过一个全局变量传递了数据，将来将使用 Realm 来保存和检索数据。
