Google Maps SDK 不会打开 pin

Question

我的应用程序中有一个谷歌地图视图，其中显示了一个图钉。

func setUpGoogleMapView() {

    let camera = GMSCameraPosition.camera(withLatitude: self.site.latitude, longitude: self.site.longitude, zoom: 15.0)
    let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
    mapView.frame = googleMapView.frame
    self.view.addSubview(mapView)

    let marker = GMSMarker()
    marker.position = CLLocationCoordinate2D(latitude: self.site.latitude, longitude: self.site.longitude)
    marker.title = self.site.name
    marker.map = mapView
}

如果我手动调用 UIApplication.shared.openURL 并通过查询传入 URL，它将以不同的模式打开（注释不显示地点的名称，而是显示纬度和经度）或者如果用户尚未安装谷歌地图。

@IBAction func directionsButtonPressed(_ sender: UIButton) {
    if (UIApplication.shared.canOpenURL(URL(string:"comgooglemaps://")!)) {

        UIApplication.shared.openURL(URL(string:
            "comgooglemaps://?center=\(self.site.latitude),\(self.site.longitude)&zoom=14&views=traffic&q=\(self.site.latitude),\(self.site.longitude)")!)
    } else {
        print("Can't use comgooglemaps://");
    }
}

如何在 Safari 中使用 UIApplication.shared.openURL 打开谷歌地图？

如果我打电话给UIApplication.shared.openURL，我应该如何让谷歌地图显示带有地点名称的图钉？

我想在使用UIApplication.shared.openURL后有相同的方向模式。

Swift 3.x：

let strPlaceName = "batumi+botanical+garden" as String!
let url = URL(string: "https://www.google.com/maps?q="+strPlaceName!)

if UIApplication.shared.canOpenURL(url!) {
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(url!, options: [:], completionHandler: nil)
    } else {
        // for iOS 10, below is deprecated
        UIApplication.shared.openURL(url!)
    }
}

目标-C：

NSString *strPlaceName = @"Batumi+Botanical+Garden";
NSString *str = [NSString stringWithFormat:@"https://www.google.com/maps/place/%@",strPlaceName];
NSURL *url = [NSURL URLWithString:str];

if([[UIApplication sharedApplication] canOpenURL:url]) {      
    if([[UIDevice currentDevice].systemVersion floatValue] >= 10.0){
        [[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil];
    } else {
        // for iOS 10, below is deprecated
        [[UIApplication sharedApplication] openURL:url];
    }
}
