Question

这就是我从相册中获取相册和照片的方式。

let connectionPhotos = FBSDKGraphRequestConnection()
let requestPhotos = FBSDKGraphRequest(graphPath: String(format:"/%@/photos",albumID), parameters: ["fields":"picture.type(large)"], HTTPMethod: "GET")
connectionPhotos.addRequest(requestPhotos) { (connection:FBSDKGraphRequestConnection!, result:AnyObject!, error:NSError!) -> Void in
    if(error != nil){
        print(error)
        self.btnFacebook.userInteractionEnabled = true
        connectionPhotos.cancel()
    }else{
        connectionPhotos.cancel()
        self.arrImages = result["data"] as! Array<Dictionary<String, String>>

        if let userWSRequestKey = TRUserModel.SharedInstance()?.userWSRequestKey{
            if userWSRequestKey != X_API_DEFAULT_KEY{
                self.callSignInWS(dict)
            } else{
                JSONParser.sharedInstance.parseRequestKeyWithURL("", requestPrm: ["string":"string"], completionHandler: { (response) -> Void in
                    if response["status"] as! Int == 1 {
                        dispatch_async(dispatch_get_main_queue(), {() -> Void in
                            self.callSignInWS(dict)
                        })
                    } else {
                        dispatch_async(dispatch_get_main_queue(), {() -> Void in
                            self.showAlertView(INTERNET_PROBLEM)
                        })
                    }
                })
            }
        } else{
            JSONParser.sharedInstance.parseRequestKeyWithURL("", requestPrm: ["string":"string"], completionHandler: { (response) -> Void in
                if response["status"] as! Int == 1 {
                    dispatch_async(dispatch_get_main_queue(), {() -> Void in
                        self.callSignInWS(dict)
                    })
                } else {
                    dispatch_async(dispatch_get_main_queue(), {() -> Void in
                        self.showAlertView(INTERNET_PROBLEM)
                    })
                }
            })
        }
    }
}
connectionPhotos.start()

我只有414 * 414像素大小的图像，我通过上面的代码得到的图像很小所以它会在我的应用程序中模糊。那么，我怎样才能获得大图像。
有什么建议吗？

Answer 1

使用此图表路径

GET /v2.6/{photo-id}/?fields=images

我得到了一系列不同大小的图像。

示例：

{ "height": 1365, "source": "...", "width": 2048 }, { "height": 960, "source": "...", "width": 1440 }, { "height": 720, "source": "...", "width": 1080 }

希望这有助于：D
