GMSMarker没有出现在地图上 [英] GMSMarker not appearing on map

问题描述

在迅速，我想显示一个带有标记的谷歌地图。
这里是故事板图片：

  var camera = GMSCameraPosition.cameraWithLatitude（-33.86，
 longitude：151.20，zoom：6）
 
 var mapView = GMSMapView.mapWithFrame（CGRectZero，camera：camera）
 mapView.myLocationEnabled = true 
 
 self.map.camera = camera 
 self.map = mapView 
 
让marker = GMSMarker（）
 marker.position = CLLocationCoordinate2DMake（-33.86，151.20）
 marker.title =title
 marker.snippet =snippet
标记。 map = mapView 
  

：'self.map = mapView'如果我写'self.view = mapView'它会正常工作，并显示我的标记。但是我在页面中还有其他视图以及mapView，'self.view = mapView'会隐藏它们。相机也去坐标。唯一的问题是标记没有出现。
我应该怎么做？谢谢

解决方案

我在Google搜索结束后解决了这个问题。关键是在mainView中使用 Container View ，并在containerView中使用以下代码初始化映射：

  var camera = GMSCameraPosition.cameraWithLatitude（-33.86，
 longitude：151.20，zoom：6）
 
 var mapView = GMSMapView.mapWithFrame（CGRectZero，camera：camera）
 mapView .myLocationEnabled = true 
 
 self.map.camera =相机
 self.view = mapView 
 
 let marker = GMSMarker（）
 marker.position = CLLocationCoordinate2DMake（-33.86,151.20）
 marker.title =title
 marker.snippet =snippet
 marker.map = mapView 
  

In swift, I want to show a google-map with a marker on it. here's storyboard image:

and here's the code

        var camera = GMSCameraPosition.cameraWithLatitude(-33.86,
            longitude: 151.20, zoom: 6)

        var mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
        mapView.myLocationEnabled = true

        self.map.camera = camera
        self.map = mapView

        let marker = GMSMarker()
        marker.position = CLLocationCoordinate2DMake(-33.86, 151.20)
        marker.title = "title"
        marker.snippet = "snippet"
        marker.map = mapView

in the line: 'self.map = mapView' if I write 'self.view = mapView' it will work fine and shows me the marker. but I have other views in the page along with mapView and 'self.view = mapView' will hide them. camera goes to the coordniates also. the only problem is that the marker is not appearing. what should I do? thanks

解决方案

I solved the problem after hours googling. the key is to use Container View inside the mainView and in the containerView initializing the map with these codes:

 var camera = GMSCameraPosition.cameraWithLatitude(-33.86,
            longitude: 151.20, zoom: 6)

        var mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
        mapView.myLocationEnabled = true

        self.map.camera = camera
        self.view = mapView

        let marker = GMSMarker()
        marker.position = CLLocationCoordinate2DMake(-33.86, 151.20)
        marker.title = "title"
        marker.snippet = "snippet"
        marker.map = mapView
