如何使用SLRequest获取大尺寸的Facebook个人资料照片？

Question

我已使用SLRequest获取个人资料信息，并且我按照Getting user profile picture in iOS6?获取个人资料图片。但它返回的图像尺寸为50x50。我需要大尺寸的个人资料图片。任何人都可以给我一些想法，使用SLRequest？

Answer 1

使用以下网址获得大图片：

https://graph.facebook.com/fb_user_id/picture?type=large

对于封面图片，请使用以下：

http://graph.facebook.com/fb_user_id?fields=cover

这将返回：

{ 
    "cover": { 
    "id": "XXX", 
    "source": "cover_image_url", 
    "offset_y": 66 
    }, 
    "id": "XXXXXX" 
} 

Answer 2

你可以得到大的图像资料图片作为

[NSURL URLWithString:@"https://graph.facebook.com/me/picture?type=large"]; 

类型参数支持

enum{square,small,normal,large} 

Answer 3

这里是你必须获得进入到Facebook账户的用户的迅速3.

1. 答案在他或她的设备中，使用accountStore API：

   func accessFacebookAccount(onCompletion: @escaping(_ tokenCredential: 
       String, 
       _ facebookAccount: ACAccount) -> Void, onError: @escaping (_ 
   errorMessage: String?) -> Void) { 
   
   
        let accountStore = ACAccountStore() 
        let facebookAccountType = accountStore.accountType(withAccountTypeIdentifier: ACAccountTypeIdentifierFacebook) 
   
        let options = [ 
        "ACFacebookAppIdKey" : "529210493918001", 
        "ACFacebookPermissionsKey" : ["email","public_profile"], 
        "ACFacebookAudienceKey" : ACFacebookAudienceOnlyMe] as [String : Any] 
   
       accountStore.requestAccessToAccounts(with: facebookAccountType, options: options) { (granted, error) in 
        if granted { 
   
   
         let fbAccount = accountStore.accounts(with: facebookAccountType).last as? ACAccount 
   
         let credential = fbAccount?.credential 
   
   
         let token = credential?.oauthToken 
         onCompletion(token!, fbAccount!) 
   
        } else { 
         let error = "Access to Facebook was not granted." 
         onError(error) 
   
        } 
       } 
   } 
   

2. 一旦获得响应，并且用户授予对帐户的访问权限。您可以使用ACAccount对象，并通过SLRequest访问Facebook的信息：

   func getFacebookInfoViaAccounts (_ fbAccount: ACAccount) { 
   
   
   let myURL = URL(string: "https://graph.facebook.com/me") 
   
   let request = SLRequest.init(forServiceType: SLServiceTypeFacebook, requestMethod: .GET, url: myURL, parameters: ["fields":"email, first_name, last_name,birthday, gender"]) 
   
   request?.account = fbAccount 
   
   request?.perform(handler: { (dataResponse, urlResponse, error) in 
   
       if error == nil { 
   
        let json = try? JSONSerialization.jsonObject(with: dataResponse!, options: [ JSONSerialization.ReadingOptions.allowFragments]) 
   
        if let dict = json as? [String: Any] { 
   
         print("My data \(dict)") 
        } 
       } 
   
   }) 
   
   let myPhotoURl = URL(string: "https://graph.facebook.com/me/picture") 
   
   let requestPhoto = SLRequest.init(forServiceType: SLServiceTypeFacebook, requestMethod: .GET, url: myPhotoURl, parameters: ["type":"large"]) 
   
   requestPhoto?.account = fbAccount 
   
   requestPhoto?.perform(handler: { (dataResponse, urlResponse, error) in 
   
       if error == nil { 
   
        print("URL DE LA PHOTO \(urlResponse?.value(forKey: "URL"))") 
       } 
   
   }) 
   
   } 
   

以上是用于获取用户的图像轮廓和代码的信息，如电子邮件地址，性别和生日。

这是像tinder这样的应用程序获取您的数据，并不要求用户登录到Facebook帐户，如果用户有他的Facebook帐户链接到他或她的iPhone。

我希望这可以帮助别人，开心编码:)。
