グラフリクエストを最新のSwift3で書き換えています。ここにあるガイドに従っています- https://developers.facebook.com/docs/Swift/graph 。
fileprivate struct UserProfileRequest: GraphRequestProtocol {
struct Response: GraphResponseProtocol {
init(rawResponse: Any?) {
// Decode JSON into other properties
}
}
let graphPath: String = "me"
let parameters: [String: Any]? = ["fields": "email"]
let accessToken: AccessToken? = AccessToken.current
let httpMethod: GraphRequestHTTPMethod = .GET
let apiVersion: GraphAPIVersion = .defaultVersion
}
fileprivate func returnUserData() {
let connection = GraphRequestConnection()
connection.add(UserProfileRequest()) {
(response: HTTPURLResponse?, result: GraphRequestResult<UserProfileRequest.Response>) in
// Process
}
connection.start()
ただし、connection.addメソッドでこのエラーが発生しています。
Type ViewController.UserProfileRequest.Response does not conform to protocol GraphRequestProtocol.
ここで何を変更すればよいのかわかりません。開発者ガイドはSwift3の最新情報ではないようですが、それが問題かどうかはわかりません。
誰がここで間違っているのかを見ることができますか?
ありがとう。
Githubの問題を参照して、解決策を見つけました。
https://github.com/facebook/facebook-sdk-Swift/issues/6
Swift 3.0およびSDK 0.2.0のFacebookドキュメントはまだ更新されていません。
これは私のために働く:
let params = ["fields" : "email, name"]
let graphRequest = GraphRequest(graphPath: "me", parameters: params)
graphRequest.start {
(urlResponse, requestResult) in
switch requestResult {
case .failed(let error):
print("error in graph request:", error)
break
case .success(let graphResponse):
if let responseDictionary = graphResponse.dictionaryValue {
print(responseDictionary)
print(responseDictionary["name"])
print(responseDictionary["email"])
}
}
}
楽しい。
このコードは私のために機能します。最初に正しい権限でログインし、次にユーザー情報を取得するためにGraphRequestを作成します。
let login: FBSDKLoginManager = FBSDKLoginManager()
// Make login and request permissions
login.logIn(withReadPermissions: ["email", "public_profile"], from: self, handler: {(result, error) -> Void in
if error != nil {
// Handle Error
NSLog("Process error")
} else if (result?.isCancelled)! {
// If process is cancel
NSLog("Cancelled")
}
else {
// Parameters for Graph Request without image
let parameters = ["fields": "email, name"]
// Parameters for Graph Request with image
let parameters = ["fields": "email, name, picture.type(large)"]
FBSDKGraphRequest(graphPath: "me", parameters: parameters).start {(connection, result, error) -> Void in
if error != nil {
NSLog(error.debugDescription)
return
}
// Result
print("Result: \(result)")
// Handle vars
if let result = result as? [String:String],
let email: String = result["email"],
let fbId: String = result["id"],
let name: String = result["name"] as? String,
// Add this lines for get image
let picture: NSDictionary = result["picture"] as? NSDictionary,
let data: NSDictionary = picture["data"] as? NSDictionary,
let url: String = data["url"] as? String {
print("Email: \(email)")
print("fbID: \(fbId)")
print("Name: \(name)")
print("URL Picture: \(url)")
}
}
}
})
これが私のコードです。私はXcode 8を使用します。Swift 3で、それは私のためにうまく機能します。
let parameters = ["fields": "email, id, name"]
let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: parameters)
_ = graphRequest?.start { [weak self] connection, result, error in
// If something went wrong, we're logged out
if (error != nil) {
// Clear email, but ignore error for now
return
}
// Transform to dictionary first
if let result = result as? [String: Any] {
// Got the email; send it to Lucid's server
guard let email = result["email"] as? String else {
// No email? Fail the login
return
}
guard let username = result["name"] as? String else {
// No username? Fail the login
return
}
guard let userId = result["id"] as? String else {
// No userId? Fail the login
return
}
}
} // End of graph request
UserProfileRequest
は次のようになります。
fileprivate struct UserProfileRequest: GraphResponseProtocol {
fileprivate let rawResponse: Any?
public init(rawResponse: Any?) {
self.rawResponse = rawResponse
}
public var dictionaryValue: [String : Any]? {
return rawResponse as? [String : Any]
}
public var arrayValue: [Any]? {
return rawResponse as? [Any]
}
public var stringValue: String? {
return rawResponse as? String
}
}
