【问题描述】：
我的 iOS 应用在注册期间使用 Facebook 的 Graph API 请求来获取用户信息，这在升级到 Facebook 的最新 SDK 之前运行良好。升级后，我收到运行时错误消息：“FBSDKLog：从 Graph API v2.4 开始，对 /me 的 GET 请求应包含明确的“字段”参数”。
代码如下：
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 = "https://graph.facebook.com/\(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)")
}
})
}
})
}
错误信息在这一行：
let birthday : NSString = (result.valueForKey("birthday") as? NSString)!
此代码在升级到 Facebook 的 SDK v4.5.1 之前运行良好，但我不知道现在要更改什么才能使其正常工作。非常感谢任何可以帮助我的人！
