如何从每个注释视图创建自定义标注按钮？

Question

我正在尝试在每个注释视图中创建一个按钮，以将用户带到自定义所选注释的新页面。我已经成功实现了 mapview 来显示带有从我的解析数据库加载的标题和副标题的注释，但我正在努力寻找一种方法 1）在注释视图中添加一个按钮以将用户带到一个新视图 2）找到一种方法选择时为每个注释创建自定义视图。任何帮助将不胜感激？

代码

class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {

    @IBOutlet weak var mapView: MKMapView!

    var MapViewLocationManager:CLLocationManager! = CLLocationManager()
    let btn = UIButton(type: .DetailDisclosure)


    override func viewDidLoad() {
        super.viewDidLoad()

        mapView.showsUserLocation = true
        mapView.delegate = self
        MapViewLocationManager.delegate = self
        MapViewLocationManager.startUpdatingLocation()
        mapView.setUserTrackingMode(MKUserTrackingMode.Follow, animated: true)

    }

    override func viewDidAppear(animated: Bool) {
        let annotationQuery = PFQuery(className: "Clubs")
        annotationQuery.findObjectsInBackgroundWithBlock {
            (clubs, error) -> Void in
            if error == nil {
                // The find succeeded.
                print("Successful query for annotations")
                // Do something with the found objects
                let myClubs = clubs! as [PFObject]
                for club in myClubs {

                    //data for annotation
                    let annotation = MKPointAnnotation()
                    let place = club["location"] as? PFGeoPoint
                    let clubName = club["clubName"] as? String
                    let stadiumName = club["stadium"] as? String
                    annotation.title = clubName
                    annotation.subtitle = stadiumName
                    annotation.coordinate = CLLocationCoordinate2DMake(place!.latitude,place!.longitude)

                    //add annotations
                    self.mapView.addAnnotation(annotation)
                }


            } else {
                // Log details of the failure
                print("Error: \(error)")
            }
        }

    }

Answer 1

对于第一个 - 您可以在 annoationView 上使用 leftCalloutAccessoryView 和 rightCalloutAccessoryView。您将必须实施 MapViewDelegate mapView(_:viewForAnnotation:).

对于 2nd - 与 calloutAccessoryView 类似，您可以访问 annoationView 上的 detailCalloutAccessoryView。您可以使用它来自定义您的标注。

Answer 2

这是 Objective-C 的解决方案，希望对你有所帮助。 要将button 设置为annotationView，

    UIButton *detailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    annotationView.rightCalloutAccessoryView = detailButton;

当click在这个按钮上执行时，跟delegate一样的方法被调用，所以也重写下面的方法，

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control

您可以在上述方法中进行任何您想要的自定义，因为您知道用户现在点击了附件视图。
