我的iOS应用程序在注册时使用Facebook的Graph API请求来获取用户信息，在升级到Facebook的最新SDK之前，该操作可以正常运行。升级后，我收到运行时错误，指出：FBSDKLog：从Graph API v2.4开始，GET请求/我应该包含一个明确的fields参数。
这是代码：
func requestFacebook（）{ let graphRequest：FBSDKGraphRequest = FBSDKGraphRequest（graphPath：me，参数：nil） graphRequest.startWithCompletionHandler（{（connection，result，error））> Void in if（（error）！= nil） { //进程错误 println（错误：\（错误））} 如果错误== nil {让生日：NSString =（result.valueForKey（birthday）as？NSString）！ var currentDate = NSDate（） var birthdayFormatter = NSDateFormatter（） let userCalendar = NSCalendar.currentCalendar（） birthdayFormatter.dateFormat =MM / DD / YYYY var birthdayNSDate = birthdayFormatter.dateFromString（生日为String） var userAge = self.calculateAge（birthdayNSDate！） PFUser.currentUser（）！[age] = userAge var facebookID：NSString =（result.valueForKey（id）as？ NSString的）！ var pictureURL =graph.facebook/\(facebookID)/picture?type=large&return_ssl_resources=1 var URLRequest = NSURL（string：pictureURL ） var URLRequestNeeded = NSURLRequest（URL：URLRequest！） NSURLConnection.sendAsynchronousRequest（URLRequestNeeded，queue：NSOperationQueue.mainQueue（），completionHandler：{（response：NSURLResponse！，data：NSData！ ，错误：NSError！） - > 如果错误== Nil { var picture = PFFile（data：data） PFUser.currentUser（）！[picture] =图片 PFUser.currentUser（）！。saveInBackgroundWithBlock（{（success，error） - > Void in 如果错误== nil { var userPicture：PFFile = PFUser。 currentUser（）!. valueForKey（picture）as！PFFile userPicture.getDataInBackgroundWithBlock {（imageData，错误） - > 如果错误== Nil { self.meProfileImageView.image = UIImage（data：imageData！） var userName：String = PFUser.currentUser（）!. valueForKey （用户名）为！ String var userAge：Int = PFUser.currentUser（）!. valueForKey（age）as！ Int self.meLabel.text =\（userName），\（userAge） self.findFriends（） } } } else { println（error）} }）} else { println（Error ：\（error.localizedDescription））} }）} }）} pre>错误信息位于以下行：
让生日：NSString =（result.valueForKey（birthday）as？NSString）！此代码在升级到Facebook的SDK v4.5.1之前运行得很好，但我不知道改变，使这项工作现在。非常感谢任何可以帮助我的人！
解决方案此行需要一个不为零的参数值
let graphRequest：FBSDKGraphRequest = FBSDKGraphRequest（graphPath：me，参数：nil）我将扩展更多，例如，这是psuedo代码：
所以对于ObjC它例如，这样，所以上面的内容将读取以下内容：
参数：@ {@fields：@ id，name}在快速这将是类似的东西
如下所示：
参数：[fields：email]这只是两个字段，再次是伪代码，但您需要指定参数
更新：此更新显示在哪里找到字段的参数如上所述，这里是一个快速链接：
这是Paramters字段信息（这应该保持与FBSDK大致静态，其中一些是核心，意味着它不会真的改变那么多，但是我会随时更新）：developers.facebook/docs/graph-api/reference/user
以下信息的格式如下，我刚刚做到这一点：

My iOS app uses Facebook's Graph API Request during sign up to get user information, which worked fine prior to upgrading to Facebook's newest SDK. After upgrading, I'm getting a runtime error stating: "FBSDKLog: starting with Graph API v2.4, GET requests for /me should contain an explicit "fields" parameter".
Here is the code:
func requestFacebook() { let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil) graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in if ((error) != nil) { // Process error println("Error: \(error)") } else if error == nil { let birthday : NSString = (result.valueForKey("birthday") as? NSString)! var currentDate = NSDate() var birthdayFormatter = NSDateFormatter() let userCalendar = NSCalendar.currentCalendar() birthdayFormatter.dateFormat = "MM/DD/YYYY" var birthdayNSDate = birthdayFormatter.dateFromString(birthday as String) var userAge = self.calculateAge(birthdayNSDate!) PFUser.currentUser()!["age"] = userAge var facebookID: NSString = (result.valueForKey("id") as? NSString)! var pictureURL = "graph.facebook/\(facebookID)/picture?type=large&return_ssl_resources=1" var URLRequest = NSURL(string: pictureURL) var URLRequestNeeded = NSURLRequest(URL: URLRequest!) NSURLConnection.sendAsynchronousRequest(URLRequestNeeded, queue: NSOperationQueue.mainQueue(), completionHandler: {(response: NSURLResponse!,data: NSData!, error: NSError!) -> Void in if error == nil { var picture = PFFile(data: data) PFUser.currentUser()!["picture"] = picture PFUser.currentUser()!.saveInBackgroundWithBlock({ (success, error) -> Void in if error == nil { var userPicture:PFFile = PFUser.currentUser()!.valueForKey("picture") as! PFFile userPicture.getDataInBackgroundWithBlock { (imageData, error) -> Void in if error == nil { self.meProfileImageView.image = UIImage(data: imageData!) var userName:String = PFUser.currentUser()!.valueForKey("username") as! String var userAge:Int = PFUser.currentUser()!.valueForKey("age") as! Int self.meLabel.text = "\(userName), \(userAge)" self.findFriends() } } } else { println(error) } }) } else { println("Error: \(error.localizedDescription)") } }) } }) }The error message is at the line:
let birthday : NSString = (result.valueForKey("birthday") as? NSString)!This code ran perfectly fine before upgrading to Facebook's SDK v4.5.1, but I don't know what to change to make this work now. Huge thanks to anyone that can help me!
解决方案this line needs a parameters value that is NOT nil
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)I'll expand more, for example, and this is psuedo code of sorts:
so for ObjC it would be this, for example, so the the above would read the following:
parameters:@{@"fields": @"id, name"}In swift it would be something similar
something like this:
parameters:["fields": "email"]This is for just two fields, and again it's psuedo code, but you need to specify the parameters
UPDATE:Im adding this update to show folks where you find the parameters for the fields as described above, here's a quick link:
Here's the Paramters field info (this should stay roughly static with FBSDK, some of this is "core" which means it won't really change that much, but I'll update whenever I can):developers.facebook/docs/graph-api/reference/user
