Question

如何在Swift中打开新的FBSession？我目前有一个Facebook登录工作正常，现在我想让一个新控制器中的朋友。

我目前有这个：

var friendsRequest : FBRequest = FBRequest.requestForMyFriends()
    friendsRequest.startWithCompletionHandler{(connection:FBRequestConnection!, result:AnyObject!, error:NSError!) -> Void in
        var resultdict = result as NSDictionary
        println("dict: \(resultdict)")
        var data : NSArray = resultdict.objectForKey("data") as NSArray

        for i in 0...data.count {
            let valueDict : NSDictionary = data[i] as NSDictionary
            let id = valueDict.objectForKey("id") as String
            println("id \(id)")
        }

        var friends = resultdict.objectForKey("data") as NSArray
        println("\(friends.count) friends")
    }

这给了我这个错误：

FBSDKLog：对端点＆＃39; me / friends＆＃39;的请求出错：必须为此端点的呼叫指定一个开放的FBSession。

我怎样才能做到这一点？我似乎无法找到这个......

var friendsRequest : FBRequest = FBRequest.requestForMyFriends()

friendsRequest.startWithCompletionHandler{(connection:FBRequestConnection!,     result:AnyObject!, error:NSError!) -> Void in

var resultdict = result as NSDictionary

println("Result Dict: \(resultdict)")

var data : NSArray = resultdict.objectForKey("data") as NSArray

    for i in 0...data.count {
        let valueDict : NSDictionary = data[i] as NSDictionary
        let id = valueDict.objectForKey("id") as String
        println("the id value is \(id)")


    }

    var friends = resultdict.objectForKey("data") as NSArray
        println("Found \(friends.count) friends")

    }
