Facebook result.isCancelled总是适用于iOS-8和iOS-9，其工作正常。

Question

Facebook版本: 4.10

我使用下面的代码

  func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    // Do what you have to do but at the end, instead of 'return true', put :

    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

func applicationDidBecomeActive(application: UIApplication) {
    FBSDKAppEvents.activateApp()
}

总能成真

if result.isCancelled {
                NSLog("Cancelled")
            }

注:只对iOS-8有问题(iOS-9工作正常)

Answer 1

我知道了为什么它是为我而坏的。我还使用Google/SignIn与Google进行身份验证。当我将cocoapods设置为pod 'Google/SignIn', '~> 2.0'时，问题就消失了。问题是application:openURL:sourceApplication:annotation在iOS 8中没有被调用。请注意，在iOS 9中不推荐这个方法。
