让我先道歉,只是快速学习,所以我不是100％做我正在做的事情.我找到了许多关于在
swift中集成facebook登录的教程,并且看起来在应用程序中有效,但似乎我的代表永远不会被调用.我期望发生的是当用户登录时应该发生两件事情.
1)facebook的登录按钮应更改为注销按钮.
2)控制台命令应该打印我登录的,最终用户信息.
ViewController类是：
class ViewController: UIViewController,FBLoginViewDelegate {
@IBOutlet var fbLoginView : FBLoginView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view,typically from a nib.
self.fbLoginView.delegate = self
self.fbLoginView.readPermissions = ["public_profile","email","user_friends"]
}
// Facebook Delegate Methods
func loginViewShowingLoggedInUser(loginView : FBLoginView!) {
println("User Logged In")
println("This is where you perform a segue.")
}
func loginViewFetchedUserInfo(loginView : FBLoginView!,user: FBGraphUser){
println("User Name: \(user.name)")
}
func loginViewShowingLoggedOutUser(loginView : FBLoginView!) {
println("User Logged Out")
}
func loginView(loginView : FBLoginView!,handleError:NSError) {
println("Error: \(handleError.localizedDescription)")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
AppDelegate部分是：
func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
FBLoginView.self
FBProfilePictureView.self
func application(application: UIApplication,openURL url: NSURL,sourceApplication: NSString?,annotation: AnyObject) -> Bool {
var wasHandled:Bool = FBAppCall.handleOpenURL(url,sourceApplication: sourceApplication)
return wasHandled
}
return true
}
正如您所看到的,大部分内容都是直接来自教程,但无法正常工作.我已经配置了我的info.plist,FBLoginView出现并通过整个身份验证,但没有任何内容打印到控制台,按钮也没有改变.当我再次尝试点击它时,我获得了已经授权的应用程序,这应该意味着auth成功,但在我的应用程序中没有触发任何内容.
我有信心我的appdelegate可能出现问题,但对于swift来说是新手,我不知道是什么……
解决方法
我想建议你检查这些步骤：
– 在您的VC类中,导入FacebookSDK语句和FBLoginViewDelegate？
– 你的出口应该是：
– 在您的VC类中,导入FacebookSDK语句和FBLoginViewDelegate？
– 你的出口应该是：
//FB outlet @IBOutlet var fbLoginView: FBLoginView
– 在您的AppDelegate.swift中,还导入了FacebookSDK？
– 你的AppDelegate.swift中的func中有一个func.It应该是：
import FacebookSDK
@UIApplicationMain
class AppDelegate：UIResponder,UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
//FB implementation
FBLoginView.self
FBProfilePictureView.self
return true
}
//FB Method handles what happens after authentication
func application (application:UIApplication,openURL url:NSURL,sourceApplication:NSString?,annotation:AnyObject) -> Bool {
//test var
var wasHandled:Bool = FBAppCall.handleOpenURL(url,sourceApplication: sourceApplication)
// attempt to extract a token from the url
return wasHandled
}
