我在我的应用程序中使用Facebook SDK v4.8.0 for iOS登录Facebook. (iPhone OS版本9.3)
以下是一些相关的集成代码：
AppDelegate.swift
func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
FBSDKApplicationDelegate.sharedInstance().application(application,didFinishLaunchingWithOptions: launchOptions)
return true
}
func applicationDidBecomeActive(application: UIApplication) {
FBSDKAppEvents.activateApp()
}
func application(application: UIApplication,openURL url: NSURL,sourceApplication: String?,annotation: AnyObject) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application,openURL: url,sourceApplication: sourceApplication,annotation: annotation)
}
func application(application: UIApplication,options: [String: AnyObject]) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application,sourceApplication: "UIApplicationOpenURLOptionsSourceApplicationKey",annotation: "UIApplicationOpenURLOptionsAnnotationKey")
}
Login.Swift
@IBAction func btnFacebook(sender: UIButton) {
self.loginToFacebookWithSuccess({ (response) -> Void in
print("Success")
}) { (error) -> Void in
print("failure")
}
func loginToFacebookWithSuccess(successBlock: () -> (),andFailure failureBlock: (NSError?) -> ()) {
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.loginBehavior = .SystemAccount
FBSDKLoginManager().logInWithReadPermissions(["public_profile","email","user_friends"],fromViewController: self,handler: { (result:FBSDKLoginManagerLoginResult!,error:NSError!) -> Void in
if error != nil {
print("error")
} else if result.isCancelled {
print("cancelled")
} else {
print("worked fine") // get Facebook user data here
}
})
}
当用户未在设备中配置Facebook帐户时,应用程序将转到浏览器并提供Facebook登录UI.一旦用户完成登录,浏览器就会重定向到应用程序.直到这一点,一切正常.
问题
当浏览器将用户重定向到App时,没有任何反应. (不会调用成功或失败的处理程序).如果用户在浏览器中点击“完成”,则会在日志中打印“已取消”.但是,对于“取消”或“好”(或说“继续作为用户名”)重定向后没有任何反应.
任何线索？
如果我错过了任何信息,请告诉我.
解决方法
我认为您的开放网址方法需要进行以下更改：
func application(_ application: UIApplication,open url: URL,options: [UIApplicationOpenURLOptionsKey: Any]) -> Bool {
let isFBURL = ((url.scheme?.hasPrefix("fb\(FBSDKSettings.appID()!)"))! && url.host == "authorize")
if isFBURL == true {
return FBSDKApplicationDelegate.sharedInstance().application(application,open: url,sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String,annotation: options[UIApplicationOpenURLOptionsKey.annotation] as? String)
}
}
如果有效,请告诉我.
