Question

我使用Google Places API，我为这个地方拍照，但我遇到了这样一个问题：对于美国加利福尼亚州圣莫尼卡圣莫尼卡码头非常受欢迎的位置，没有照片。我开始研究这个问题，并通过Google Places Finder为此网站返回了什么ID，我又返回了另一个ID，我尝试了我返回网页版本的ID，用于上传照片并成功下载了照片。我在iOS版本中获得了EjJTYW50YSBNb25pY2EgUGllciwgU2FudGEgTW9uaWNhLCBDQSwgVW5pdGVkIFN0YXRlcw地方ID，ChIJm6deTdekwoARTY_RzhoRms0地点ID为Google Places Finder。

import GooglePlaces

class GooglePlacesManager {

    private let gmsPlacesClient = GMSPlacesClient()

    func loadPhotosForPlace(_ placeID: String, success: ((_ photos: [UIImage]) -> Void)?, fail: ((_ error: Error) -> Void)?) {
        gmsPlacesClient.lookUpPhotos(forPlaceID: placeID) { [weak self] (photos, error) -> Void in
            guard error == nil else {
                debugPrint("loadPhotosForPlace", error!.localizedDescription)
                fail?(error!)
                return
            }
            guard let results = photos?.results else {
                success?([])
                return
            }
            var resultCount = results.count

            debugPrint("first result count", resultCount)

            if resultCount == 0 {
                success?([])
                return
            }

            var photos = [UIImage]()

            guard self != nil else { return }
            for result in results {
                self!.loadImageForMetadata(photoMetadata: result, success: { (photo) in
                    photos.append(photo)
                    if resultCount == photos.count {
                        success?(photos)
                    }
                }, notExist: {
                    resultCount -= 1
                    if resultCount == photos.count {
                        success?(photos)
                    }
                }, fail: { (error) in
                    resultCount -= 1
                    if resultCount == photos.count {
                        success?(photos)
                    }
                })
            }
        }
    }

    private func loadImageForMetadata(photoMetadata: GMSPlacePhotoMetadata, success: ((_ photo: UIImage) -> Void)?, notExist: (() -> Void)?, fail: ((_ error: Error) -> Void)?) {
        gmsPlacesClient.loadPlacePhoto(photoMetadata, callback: {
            (photo, error) -> Void in
            guard error == nil else {
                debugPrint("loadPhotosForPlace", error!.localizedDescription)
                fail?(error!)
                return
            }
            guard photo != nil else {
                notExist?()
                return
            }
            success?(photo!)
        })
    }

    func getLocationInfo(_ placeID: String, success: ((_ place: GMSPlace) -> Void)?, fail: ((_ error: Error) -> Void)?) {
        gmsPlacesClient.lookUpPlaceID(placeID) { (place, error) in
            guard error == nil else {
                debugPrint(error!.localizedDescription)
                fail?(error!)
                return
            }
            guard place != nil else { return }
            success?(place!)
        }
    }

}

请告诉我如何修复它？

更新：我在这个loadPhotosForPlace函数

中添加了这些代码行

   gmsPlacesClient.lookUpPlaceID(placeID, callback: { (place, error) -> Void in
            if let error = error {
                print("lookup place id query error: \(error.localizedDescription)")
                return
            }

            guard let place = place else {
                print("No place details for \(placeID)")
                return
            }

            print("Place name \(place.name)")
            print("Place address \(place.formattedAddress)")
            print("Place placeID \(place.placeID)")
            print("Place attributions \(place.attributions)")
        })

我收到了这些日志，但是我没有收到任何照片。

Place name Santa Monica Pier
Place address Optional("Santa Monica Pier, Santa Monica, CA 90401, USA")
Place placeID EjJTYW50YSBNb25pY2EgUGllciwgU2FudGEgTW9uaWNhLCBDQSwgVW5pdGVkIFN0YXRlcw
Place attributions nil

Google Places SDK不会返回热门地点的照片。 iOS版
