我有一個mapView
自定義註釋。我還爲此添加了一個按鈕,但是有沒有辦法查看該按鈕在哪個註釋上被按下?Swift Annotation CallOut按鈕選擇
所以發佈到控制檯不應該只是「Disclosure Pressed!」。我需要類似「Disclosure Pressed!info(X) .subtitle」來查看用戶錄製的info1或info2。
下面是代碼:
import UIKit
import MapKit
class ViewController: UIViewController, MKMapViewDelegate {
@IBOutlet weak var Map: MKMapView!
class CustomPointAnnotation: MKPointAnnotation {
var imageName: String!
}
@IBAction func btpressed(sender: AnyObject) {
}
override func viewDidLoad() {
super.viewDidLoad()
//1
var lat1:CLLocationDegrees = 40.748708
var long1:CLLocationDegrees = -73.985643
var latDelta1:CLLocationDegrees = 0.01
var longDelta1:CLLocationDegrees = 0.01
var span1:MKCoordinateSpan = MKCoordinateSpanMake(latDelta1, longDelta1)
var location1:CLLocationCoordinate2D = CLLocationCoordinate2DMake(lat1, long1)
var region1:MKCoordinateRegion = MKCoordinateRegionMake(location1, span1)
Map.setRegion(region1, animated: true)
var info1 = CustomPointAnnotation()
info1.coordinate = location1
info1.title = "Test Title1!"
info1.subtitle = "Subtitle1"
info1.imageName = "1.png"
Map.addAnnotation(info1)
//2
var lat2:CLLocationDegrees = 41.748708
var long2:CLLocationDegrees = -72.985643
var latDelta2:CLLocationDegrees = 0.01
var longDelta2:CLLocationDegrees = 0.01
var span2:MKCoordinateSpan = MKCoordinateSpanMake(latDelta2, longDelta2)
var location2:CLLocationCoordinate2D = CLLocationCoordinate2DMake(lat2, long2)
var region2:MKCoordinateRegion = MKCoordinateRegionMake(location2, span2)
var info2 = CustomPointAnnotation()
info2.coordinate = location2
info2.title = "Test Title2!"
info2.subtitle = "Subtitle2"
info2.imageName = "2.png"
Map.addAnnotation(info2)
}
func mapView(mapView: MKMapView!, annotationView: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
if control == annotationView.rightCalloutAccessoryView {
println("Disclosure Pressed!")
}
}
func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {
if !(annotation is CustomPointAnnotation) {
return nil
}
let reuseId = "test"
var anView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId)
if anView == nil {
anView = MKAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
anView.canShowCallout = true
anView.rightCalloutAccessoryView = UIButton.buttonWithType(.InfoDark) as UIButton
var imageview = UIImageView(frame: CGRectMake(0, 0, 10, 10))
imageview.image = UIImage(named: "1.png")
anView!.leftCalloutAccessoryView = imageview
} else {
anView.annotation = annotation
}
//Set annotation-specific properties **AFTER**
//the view is dequeued or created...
let cpa = annotation as CustomPointAnnotation
anView.image = UIImage(named:cpa.imageName)
return anView
}
}
我已經嘗試過這樣的:
if control == annotationView.rightCalloutAccessoryView {
println("Disclosure Pressed!" \(self.subtitle))
}
