Facebook IOS SDK - 如何知道何时返回应用程序

Question

How i know, when the user authorize the app, or not, and the SDK goes back to my app? Theres any event to know that?

Answer 1

-(BOOL) application:(UIApplication *)application handleOpenURL:(NSURL *)url{}

你也必须在你的.plist中设置URL Schemes

Answer 2

in your appdelegate

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation

and you can inspect the sourceApplication.

Also in the applicationDidBecomeActive: remember to call [FBSession.activeSession handleDidBecomeActive];
