如何使用FBSDKLoginManager实现FB登录？

Question

使用此方法时 ([login logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)

始终将结果作为isCancelled传递给YES。将AccessToken设为null

Answer 1

在applicationDidFinishLaunching

中添加以下行

return [[FBSDKApplicationDelegate sharedInstance] application:application
                                    didFinishLaunchingWithOptions:launchOptions];

并在AppDelegate.m

中添加此方法

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation];
}

信用转到FBSDKLoginManager logInWithPublishPermissions always returns isCancelled=YES
