如何使用swift在谷歌地图中创建自定义图标视图?
我需要这样做如何使用swift在谷歌地图中创建自定义图标视图?,swift,google-maps-sdk-ios,Swift,Google Maps Sdk Ios,我需要这样做 google maps sdk for iOS中带有静态标签的标记如果有很多标记,我不建议使用iconView,因为它会使UI变得非常滞后,但下面是: 将UIView文件创建为“MarkerInfoView”,该文件将创建为MarkerInfoView.xib 然后在其中设计UI,为图标添加imageView,然后添加其他必要的视图以完成图标视图。还将标记作为图像视图包含在设计中。因为我不是100%确定,但我认为你不能在谷歌地图中同时使用iconView和icon 然后创建一个名
google maps sdk for iOS中带有静态标签的标记如果有很多标记,我不建议使用iconView,因为它会使UI变得非常滞后,但下面是: 将UIView文件创建为“MarkerInfoView”,该文件将创建为
MarkerInfoView.xib
然后在其中设计UI,为图标添加imageView,然后添加其他必要的视图以完成图标视图。还将标记作为图像视图包含在设计中。因为我不是100%确定,但我认为你不能在谷歌地图中同时使用iconView和icon
然后创建一个名为“MarkerInfoView.swift”的swift文件,转到MarkerInfoView.xib
并将其类选择为MarkerInfoView
然后创建另一个swift文件,将其命名为PlaceMarker
,在该文件中,您将创建一个符合GMSMarker的类,然后您将初始化视图,将其设置为PlaceMarker
类中的iconView
。让我们按照以下步骤进行操作:
class PlaceMarker: GMSMarker {
//Initialize with lat and long, then set position equal to the coordinate.
// 'position' comes from inheriting from GMSMarker, which is google marker.
init(latitude: Double, longitude: Double, distance: Double, placeName: String) {
super.init()
if let lat: CLLocationDegrees = latitude,
let long: CLLocationDegrees = longitude {
let coordinate = CLLocationCoordinate2D(latitude: lat, longitude: long)
position = coordinate
}
let view = Bundle.main.loadNibNamed("MarkerInfoView", owner: nil, options: nil)?.first as! MarkerInfoView
// you can set your view's properties here with data you are sending in initializer.
// Remember if you need to pass more than just latitude and longitude, you need
// to update initializer.
// lets say you created 2 outlet as placeNameLabel, and distanceLabel, you can set
// them like following:
view.placeNameLabel.text = placeName
view.distanceLabel.text = distance
// Once your view is ready set iconView property coming from inheriting to
// your view as following:
iconView = view
appearAnimation = .pop //not necessarily but looks nice.
}
}
然后,当您在ViewController
中拥有数据和googlemaps视图时,您可以设置如下:
let latitude = 101.432432 //arbitrary, should come from your source
let longitude = 34.432124
let distance = 4
let placeName = "My place".
let marker = PlaceMarker(latitude: latitude, longitude: longitude, distance: distance, placeName: placeName)
marker.map = self.mapView // your google maps set your marker's map to it.
iconView
正在更改其位置,我们必须设置groundAnchor
,以确保它将位于默认标记的准确位置。感谢@Hemang,如果您愿意,请随时编辑答案,以便将来为其他人提供更好的解决方案。
