我正在使用Google Places API，并实施了pickPlace功能，如下所示：
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 {
// Set place to class variable selectedPlace
self.selectedPlace = place
// Add marker & move camera to new place
if self.selectedPlace != nil {
let cam = GMSCameraPosition.camera(withTarget: (self.selectedPlace?.coordinate)!, zoom: 18)
let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: cam)
let newPlaceMarker = GMSMarker(position: (self.selectedPlace?.coordinate)!)
newPlaceMarker.map = mapView
self.navigationItem.title = self.selectedPlace?.name
print(self.selectedPlace?.website)
newPlaceMarker.title = self.selectedPlace?.name
self.view = mapView
}
} else {
self.navigationItem.title = "No place selected"
}
})
}
因此，这允许用户搜索“Starbucks”这样的地方并将place设置为变量var selectedPlace: GMSPlace?（在类范围内声明）：地图移动到那里，在该位置添加标记，将navigationItem.title更改为selectedPlace.name，并将网站打印到控制台 - 到目前为止一切都很好。
现在我想点击标记时会弹出一个信息窗口，就像我用其他一些我硬编码的默认标记一样。这是infoWindow函数：
func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {
let customInfoWindow = Bundle.main.loadNibNamed("CustomInfoWindow", owner: self, options: nil)?[0] as! CustomInfoWindow
let placeName = marker.title!
switch placeName {
case "TGI Friday's":
customInfoWindow.nameLbl.text = "TGI Friday's"
customInfoWindow.detailLabel.text = "Thoroughly Average Chain Restaurant"
customInfoWindow.placeImage.image = UIImage(named: "fridays")
self.navigationItem.title = "TGI Friday's"
case "George's":
customInfoWindow.nameLbl.text = "George's"
customInfoWindow.detailLabel.text = "Old School Diner"
customInfoWindow.placeImage.image = UIImage(named: "georges")
self.navigationItem.title = "George's"
case "Reserve Cut":
customInfoWindow.nameLbl.text = "Reserve Cut"
customInfoWindow.detailLabel.text = "Kosher Steakhouse"
customInfoWindow.placeImage.image = UIImage(named: "reserveCut")
self.navigationItem.title = "Reserve Cut"
case "O'Hara's":
customInfoWindow.nameLbl.text = "O'Hara's"
customInfoWindow.detailLabel.text = "Irish Pub"
customInfoWindow.placeImage.image = UIImage(named: "oharas")
self.navigationItem.title = "O'Hara's"
case "Bill's Bar & Burger":
customInfoWindow.nameLbl.text = "Bill's Bar & Burger"
customInfoWindow.detailLabel.text = "Bar founded by Bill that also has burgers"
customInfoWindow.placeImage.image = UIImage(named: "bills")
self.navigationItem.title = "Bill's Bar & Burger"
default:
customInfoWindow.nameLbl.text = self.selectedPlace?.name
customInfoWindow.detailLabel.text = self.selectedPlace?.formattedAddress
customInfoWindow.placeImage.image = UIImage(named: "noImageFound")
self.navigationItem.title = self.selectedPlace?.name
}
return customInfoWindow
}
当我点击我的硬编码默认标记时，我的自定义窗口弹出正常，但不是用户选择的位置。标题会弹出默认信息窗口，但不会弹出我的自定义窗口。有谁知道发生了什么以及如何让它发挥作用？
编辑：如果我print(selectedPlace?.website)处于不同的功能，那就是零。不确定为什么它在pickPlace函数中工作正常但不在外部 - 这就是我设置self.selectedPlace = place的原因，所以我可以在我的课堂上使用它。
无论如何，这就是我认为导致问题的原因，但我不知道为什么或如何解决它。所以，如果有人能帮我解决这个问题，那就太棒了。
