Question

我正在使用FBSDKCoreKit(4.12.0)FBSDKLoginKit(4.12.0)我首先得到屏幕1

这种方法永远不会被调用.

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:@[@"email",@"public_profile"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
    //never called
}];

得到这个警告

Answer 1

我如何找到解决上述问题的方法是

1)早些时候我已经创建了一个按钮,并给出了FBLoginButton类,并且我在编写动作时就像

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:@[@"email",@"public_profile"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
    //never called
}];

解决方案的修改:删除了FBLoginButton类并仅放置了UIButton

2)使用AppDelegate中编写的ios 8和ios 9方法.

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options {
    return [[FBSDKApplicationDelegate sharedInstance] application:app
                                                          openURL:url
                                                sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                                       annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
}

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

    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation
            ];
}
