如何使用标注按钮打开新的uiview控制器。(Swift)
如何使用标注按钮打开新的uiview控制器。(Swift)
提问于 2016-07-22 09:32:12
我在地图上放了几个别针，例如，对应于不同的桥梁位置。当点击这些引脚时，每个引脚都有自己的注释，显示它们的标题和字幕。我在这些注释中添加了一个info按钮。但是，我不知道如何打开一个新的UiViewController，它将根据按下哪个桥信息按钮来改变UiViewController上显示的信息。
因此，基本上我需要知道如何: 1:当按下注释中的info按钮时，打开一个UiViewController。2:更改关于按下哪个网桥信息按钮的UiViewController开销的信息。
以下是我到目前为止所拥有的：
mapView.delegate = self
//bridges
var Bridge1 = CLLocationCoordinate2DMake(48.60,2.90)
var bridge2 = CLLocationCoordinate2DMake(48.61, 2.91)
var bridge3 = CLLocationCoordinate2DMake(48.62, 2.92)
var bridge4 = CLLocationCoordinate2DMake(48.63, 2.93)
var bridge5 = CLLocationCoordinate2DMake(48.64, 2.94)
var bridge6 = CLLocationCoordinate2DMake(48.65, 2.95)
var span = MKCoordinateSpanMake(0.4, 0.4)
var region = MKCoordinateRegion(center: Bridge1, span: span)
mapView.setRegion(region, animated: true)
var Bridge1pin = MKPointAnnotation()
Bridge1pin.coordinate = Bridge1
Bridge1pin.title = "Bridge1"
Bridge1pin.subtitle = "This is bridge 1"
mapView.addAnnotation(Bridge1pin)
var bridge2pin = MKPointAnnotation()
bridge2pin.coordinate = bridge2
bridge2pin.title = "Bridge2"
bridge2pin.subtitle = "This is bridge 2"
mapView.addAnnotation(bridge2pin)
var bridge3pin = MKPointAnnotation()
bridge3pin.coordinate = bridge3
bridge3pin.title = "Bridge3"
bridge3pin.subtitle = "This is bridge 3"
mapView.addAnnotation(bridge3pin)
var bridge4pin = MKPointAnnotation()
bridge4pin.coordinate = bridge4
bridge4pin.title = "Bridge4"
bridge4pin.subtitle = "This is bridge 4"
mapView.addAnnotation(bridge4pin)
var bridge5pin = MKPointAnnotation()
bridge5pin.coordinate = bridge5
bridge5pin.title = "bridge5"
bridge5pin.subtitle = "hello this is bridge 5"
mapView.addAnnotation(bridge5pin)
var bridge6pin = MKPointAnnotation()
bridge6pin.coordinate = bridge6
bridge6pin.title = "bridge6"
bridge6pin.subtitle = "hello this is bridge 6"
mapView.addAnnotation(bridge6pin)
}
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
let reuseIdentifier = "pin"
var pin = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseIdentifier) as? MKPinAnnotationView
if pin == nil {
pin = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseIdentifier)
pin!.pinColor = .Red
pin!.canShowCallout = true
pin!.rightCalloutAccessoryView = UIButton(type: .DetailDisclosure)
} else {
pin!.annotation = annotation
}
return pin
}

您可以了解不同视图之间的导航( 在这个链接里。 )。
我将给出一些导航提示，并为导航准备数据。
1.检测用户单击桥的时间
为此，您只需要实现一个名为calloutAccessoryControlTapped的标注方法，如下所示。
func mapView(mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
performSegueWithIdentifier("info", sender: view)
// Above line of code is used for the segue operation between multiple MVCs.
}2.您需要添加segue操作
这可以通过控件从您的主要视图拖动到故事板上的详细视图，并在弹出窗口和属性检查器中选择as ，并在属性检查器中将标识符添加为info。
3.为抽头桥准备模型
为此，只需重写prepareForSegue方法，如下所示。
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
//Just validating by checking the same identifier
if (segue.identifier == "info") {
if let annotation = sender as? MKAnnotationView {
let detailViewController = segue.destinationViewController as! DetailViewController
detailViewController.titleText = annotation.annotation?.title ?? ""
detailViewController.detaileText = annotation.annotation?.subtitle ?? ""
}
}
}4.这里是DetailViewController.
它现在只有两个标签，用于显示标题和字幕。
import UIKit
class DetailViewController: UIViewController {
@IBOutlet weak var titleLabel: UILabel!
@IBOutlet weak var detailLabel: UILabel!
var titleText: String? { didSet { updateUI() } }
var detaileText: String? { didSet { updateUI() } }
override func viewDidLoad() {
super.viewDidLoad()
updateUI()
}
private func updateUI() {
self.titleLabel?.text = self.titleText
self.detailLabel?.text = self.detaileText
}
