如何在不點擊標記的情況下在 iOS 谷歌地圖中顯示信息窗口？

Question

我是 iOS 開發的新手。 這是關於 Google Maps iOS SDK 中的標記信息窗口。

我明白，我們可以使用 GMSMarkerOption 創建一個帶有信息窗口的標記。

GMSMarkerOption *myLocationOption = [GMSMarkerOption alloc];
myLocationOption .title = @"My Location";
myLocationOption .snippet = @"Lat:...., Lang:....";

[mapView addMarkerOption:myLocationOption];

根據上面的代碼，標記按預期顯示在地圖視圖中。 點擊標記會顯示谷歌地圖中的“我的位置”信息窗口，這很好。

無論如何，當用戶轉到自定義地圖屏幕時，我們可以以編程方式顯示信息窗口嗎？

Answer 1

這在Google Maps SDK上已更改，更容易理解：

GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = coordinate;
marker.title = @"Location selected";
marker.snippet = @"Testing";
marker.map = mapView_;

//Show info window on map
[mapView_ setSelectedMarker:marker];

您現在使用setSelectedMarker方法顯示標記的信息窗口

Answer 2

GMSMarkerOptions *myLocationOptions = [GMSMarkerOptions options];
myLocationOptions.title = @"My Location";
myLocationOptions.snippet = @"Lat:...., Lang:....";

mapView.selectedMarker = [mapView addMarkerWithOptions:myLocationOptions];

（請注意，它是選項，而不是選項）

斯威夫特3.0

func addMarker(_ location:CLLocation){
        var locationMarker: GMSMarker!
        if locationMarker != nil {
            locationMarker.map = nil
        }
        locationMarker = GMSMarker(position: location.coordinate)
        locationMarker.map = mapView
        locationMarker.appearAnimation = kGMSMarkerAnimationPop
        locationMarker.icon = GMSMarker.markerImage(with: UIColor.green)
        locationMarker.opacity = 0.85
        locationMarker.isFlat = true
        locationMarker.snippet = "My Location"
        mapView.selectedMarker=locationMarker

    }

下面的線是答案

mapView.selectedMarker=locationMarker

迅捷3

self.mapView.selectedMarker = marker

對於snipet 3，您可以在selectedMarker的snipet處打開snipet

如果您以類似的方式創建標記：

marker.position = CLLocationCoordinate2D(latitude: 34.1331168, longitude: -118.3550723)
marker.title = "My super place name"
marker.snippet = "Are you looking a place to play? This is your place! "
marker.appearAnimation = kGMSMarkerAnimationPop
marker.map = self.mapView

Answer 5

   // Below line will shows the infowindow for marker with out tapping on it
   [mapView setSelectedMarker:myLocationOptions]; // myLocationOptions is your desired GMSMarker to show Infowindow with out tapping .

快樂編碼:)

Answer 6

mMapView.selectedMarker =標記

Answer 7

->它顯示多個infoWindows，而無需點擊標記。 您可以輕松地對其進行自定義。

為我在0 ..

        let dict = arrNearByPlacesArray.object(at: i) as? NSDictionary ?? [:]

        let lat = dict.object(forKey: "latitude") as? String ?? ""
         let long = dict.object(forKey: "longitude") as? String ?? ""
        let company_id = dict.object(forKey: "company_id") as? String ?? ""
        let totaljobs = dict.object(forKey: "totaljobs") as? String ?? ""


        let location = CLLocationCoordinate2D(latitude: Double(lat) ?? 0.0, longitude: Double(long) ?? 0.0)
        print("location: \(location)")
        let marker = GMSMarker()
        //marker.icon = UIImage(named: "maps")

        let viewData = Bundle.main.loadNibNamed("MarkerXibView", owner: self, options: nil)?.first as! MarkerXibView .      //UIView


        marker.iconView = viewData .      //UIView


        marker.position = location
        marker.accessibilityLabel  = company_id
        marker.map = vwGoogleMap

}

不建議使用GMSMarkerOptions。 使用此功能，我無需點擊即可顯示信息窗口-

func mapView(_ mapView: GMSMapView, idleAt position: GMSCameraPosition) {
    myMapView.selectedMarker = myGMSMarker
}
