Question

我实施了Google文档中的pickPlace功能：

func pickPlace() {
    let center = CLLocationCoordinate2D(latitude: 40.708637, longitude: -74.014839)
    let northEast = CLLocationCoordinate2D(latitude: center.latitude + 0.001, longitude: center.longitude + 0.001)
    let southWest = CLLocationCoordinate2D(latitude: center.latitude - 0.001, longitude: center.longitude - 0.001)
    let viewport = GMSCoordinateBounds(coordinate: northEast, coordinate: southWest)
    let config = GMSPlacePickerConfig(viewport: viewport)
    let placePicker = GMSPlacePicker(config: config)

    placePicker.pickPlace(callback: {(place, error) -> Void in
        if let error = error {
            print("Pick Place error: \(error.localizedDescription)")
            return
        }

        if let place = place {
            self.navigationItem.title = place.name
            if let website = place.website {
                self.webView.load(URLRequest(url: website))
                self.view = self.webView
                print(website)
            }
            let camera = GMSCameraPosition.camera(withLatitude: 40.708637, longitude: -74.014839, zoom: 18)

            let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
            self.view = mapView

        } else {
            self.navigationItem.title = "No place selected"
        }
    })
}

并添加到if let website = place.website条件内的webView请求中。当我运行应用程序并选择一个位置时，print语句使用正确的URL运行，但webView不会加载。谁能看到我做错了什么？

最终，我希望能够在pickPlace函数之外使用该网站，并在我的didTapWindowOf函数中使用它。也许通过初始化像var site: URL?这样的变量并将place.website（unwrapped）设置为该变量。然后在didTapWindowOf我只使用self.webView.load(URLRequest(url: site))。但我相对较新，这种做法对我不起作用，所以任何帮助都会受到赞赏！

Google Places API - 如何在选择位置时加载网站？
