这对你来说可能是有用的，并且下面还显示了一些facebook的委托方法

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { return [facebook handleOpenURL:url]; } - (void)applicationDidBecomeActive:(UIApplication *)application { // Although the SDK attempts to refresh its access tokens when it makes API calls, // it's a good practice to refresh the access token also when the app becomes active. // This gives apps that seldom make api calls a higher chance of having a non expired // access token. [[self facebook] extendAccessTokenIfNeeded]; } - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { NSLog(@"url->%@",url); return [self.facebook handleOpenURL:url]; } - (BOOL)isFBLoggedIn { return [facebook isSessionValid]; } - (void)login { if (![facebook isSessionValid]) { [facebook authorize:[[NSArray alloc] initWithObjects:@"offline_access", nil]]; } else { [facebook logout]; [facebook authorize:[[NSArray alloc] initWithObjects:@"offline_access", nil]]; } } - (void)fetchFBFriends { [facebook requestWithGraphPath:@"me/friends" andDelegate:self]; } -(void)fetchFbDetails { [facebook requestWithGraphPath:@"me" andDelegate:self]; } - (void)storeAuthData:(NSString *)accessToken expiresAt:(NSDate *)expiresAt { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setObject:accessToken forKey:@"FBAccessTokenKey"]; [defaults setObject:expiresAt forKey:@"FBExpirationDateKey"]; [defaults synchronize]; } NSString *strRes = [NSString stringWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/me?fields=name,username,email,gender,birthday,hometown,picture&access_token=%@",facebook.accessToken]] usedEncoding:&encoding error:&error]; NSMutableDictionary *dirFbDetails = [[NSMutableDictionary alloc] initWithDictionary:[strRes JSONValue]]; -(void)fbDidExtendToken:(NSString *)accessToken expiresAt:(NSDate *)expiresAt { NSLog(@"token extended"); [self storeAuthData:accessToken expiresAt:expiresAt]; } -(void)doFaceBookLogin { [self.facebook authorize:[NSArray arrayWithObjects:@"friends_birthday",@"user_birthday",@"email",@"publish_stream",nil]]; } #pragma mark - FBRequestDelegate Methods - (void)request:(FBRequest *)request didReceiveResponse:(NSURLResponse *)response { } - (void)request:(FBRequest *)request didLoad:(id)result { } - (void)request:(FBRequest *)request didFailWithError:(NSError *)error { NSLog(@"Err message: %@", [[error userInfo] objectForKey:@"error_msg"]); NSLog(@"Err code: %d", [error code]); }
