问题描述
我尝试根据用户的位置从foursquare提取一些餐厅数据，但出现一堆查询错误。
这是位置代码：
protocol UserLocationDelegate {
func tracingLocation(currentLocation: CLLocation)
}
class UserLocation: NSObject {
static let shared = UserLocation()
var delegate: UserLocationDelegate?
var userCurrentLocation: CLLocationCoordinate2D?
var locationManager: CLLocationManager?
func locationManagerStart() {
if locationManager == nil {
locationManager = CLLocationManager()
locationManager?.requestWhenInUseAuthorization()
locationManager?.distanceFilter = 1000
locationManager?.desiredAccuracy = kCLLocationAccuracyBest
locationManager?.delegate = self
}
locationManager?.startUpdatingLocation()
}
func locationManagerStop() {
if locationManager != nil {
locationManager?.stopUpdatingLocation()
}
}
private func upataLocation(currentLocation: CLLocation) {
delegate?.tracingLocation(currentLocation: currentLocation)
}
}
extension UserLocation: CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager,didUpdateLocations locations: [CLLocation]) {
if let location = locations.last {
upataLocation(currentLocation: location)
userCurrentLocation = location.coordinate
}
}
func locationManager(_ manager: CLLocationManager,didChangeAuthorization status: CLAuthorizationStatus) {
switch status {
case .notDetermined:
manager.requestWhenInUseAuthorization()
case .authorizedWhenInUse:
manager.startUpdatingLocation()
case .authorizedAlways:
manager.startUpdatingLocation()
case .restricted:
print("got error here,Authorization has been restriced")
case .denied:
locationManager = nil
print("got error here,Authorization has been denied")
@unkNown default:
break
}
}
func locationManager(_ manager: CLLocationManager,didFinishDeferredUpdatesWithError error: Error?) {
if let error = error {
print(error.localizedDescription)
}
}
}
这是API代码， 因为“地点/搜索”不包含有关地点的详细数据。 所以我必须分开 首先，获取场馆的ID，然后使用ID来获取场馆的详细信息
然后，我将记录限制设置为“ 50”，这意味着我应该对Foursquare服务器获得50个响应。
class FoursquareAPI: NSObject,CLLocationManagerDelegate {
let categoryId = "4d4b7105d754a06374d81259" //food category
let client = Foursquareapiclient(clientId: clientId,clientSecret: clientSecret)
func getDataFromJSON(with location: CLLocation,completion: @escaping (Data?,Error?) -> Void) {
let parameter:[String:String] = ["ll": "\(location.coordinate.latitude),\(location.coordinate.longitude)","limit": "50","categoryId": categoryId]
client.request(path: "venues/search",parameter: parameter) {result in
switch result {
case let .success(data):
completion(data,nil)
//print(data)
case let .failure(error):
completion(nil,error)
}
}
}
func getVenuesData(with VenueID: String,Error?) -> Void) {
let parameter: [String: String] = ["VENUE_ID": VenueID]
client.request(path: "venues/\(VenueID)",nil)
case let .failure(error):
completion(nil,error)
}
}
}
}
通过用户地理位置参数调用api， 以下是一些条件： 1，app首次启动？ 2，用户自上次数据获取以来的移动距离
func tracingLocation(currentLocation: CLLocation) {
self.userCurrentLocation = currentLocation
let userMoved = currentLocation.distance(from: CLLocation(latitude: UserDefaults.standard.double(forKey: "userLastLat"),longitude: UserDefaults.standard.double(forKey: "userLastLong")))
if UserDefaults.standard.bool(forKey: "isFirstLaunch") || userMoved > 1000 {
loadBaseJSONData(with: currentLocation)
UserDefaults.standard.set(currentLocation.coordinate.latitude,forKey: "userLastLat")
UserDefaults.standard.set(currentLocation.coordinate.longitude,forKey: "userLastLong")
UserDefaults.standard.set(false,forKey: "isFirstLaunch")
}else {
print(userMoved as Any)
print("called step 3")
return
}
}
api调用链并将数据保存到CoreData：
//MARK: - JSON
func loadBaseJSONData(with location: CLLocation) {
FoursquareAPI().getDataFromJSON(with: location){ (data,error) in
if let error = error {
print(error.localizedDescription)
return
}
guard let data = data else {return}
self.venuesBaseData = self.parseBaseJSON(data: data)
}
}
func parseBaseJSON(data: Data) -> [VenueBaseData] {
let decoder = JSONDecoder()
do {
let loadDataStore = try decoder.decode(RootClass.self,from: data)
self.venuesBaseData = loadDataStore.rootClass.venuesBaseData
for value in self.venuesBaseData {
loadVenuesJSON(whit: value.venueid)
}
}catch {
print(error)
}
return venuesBaseData
}
func loadVenuesJSON(whit venueID: String) {
FoursquareAPI().getVenuesData(with: venueID,completion: {(data,error) in
if let error = error {
print(error)
return
}
guard let data = data else {return}
self.venue = self.parseVenueJSON(data: data)
//self.tableView.reloadData()
})
}
func parseVenueJSON(data: Data) -> Venue {
let decoder = JSONDecoder()
do {
let loadDataStore = try decoder.decode(Response<SearchResponse>.self,from: data)
self.venue = loadDataStore.response.venues
if venue.photo.photoCount != 0 && venue.location.address != nil && venue.tips?.tipsCount != 0 {
var restaurant: RestaurantMO!
if let appdelegate = (UIApplication.shared.delegate as? AppDelegate) {
restaurant = RestaurantMO(context: appdelegate.persistentContainer.viewContext)
restaurant.id = venue.venueId
restaurant.name = venue.name
restaurant.type = venue.categories?[0].name
restaurant.location = venue.location.address
restaurant.phone = venue.contact.phone
restaurant.imageURL = venue.photo.group?[0].item?[0].venuePhotoURL
restaurant.summary = venue.tips?.tipsGroups?[0].tipsItems?[0].summary
restaurant.lat = venue.location.latitude!
restaurant.long = venue.location.longitude!
restaurant.distance = (self.userCurrentLocation?.distance(from: CLLocation(latitude: restaurant.lat,longitude: restaurant.long)))!
if let url = restaurant.imageURL {
URLSession.shared.dataTask(with: URL(string: url)!) {(data,response,error) in
if let error = error {
print(error)
return
}
if let data = data,let image = UIImage(data: data) {
dispatchQueue.main.sync {
restaurant.image = image.pngData()
appdelegate.saveContext()
}
}
}.resume()
}
appdelegate.saveContext()
}
}
}catch{
print(error)
}
return venue
}
所有这些之后， 我有14条记录显示在tableView上。 并在调试区域出现一堆错误：
