self presentViewController：viewController 动画：YES 不工作

Question

我没有使用任何类型的豆荚（不使用可可豆荚）

我已将我的AppController 设置如下：（这是我的viewController）

@interface AppController : UIViewController <UIApplicationDelegate, GIDSignInDelegate , GIDSignInUIDelegate>

然后当我打电话时：[[GIDSignIn sharedInstance] signIn]; 那么：

[self presentViewController:viewController animated:YES completion:nil];

创建问题并向我显示错误：

其视图不在窗口层次结构中！

或者如果我删除 UIViewController 并将其替换为 UIResponder 则错误：

UIDelegate 必须是 |UIViewController|或实施 |signIn:presentViewController:|和 |signIn:dismissViewController:| 来自|GIDSignInUIDelegate|的方法

我只想显示google sign-in UI：

我错过了什么？ 我对控制器做错了吗？ 我在这里真的需要帮助。 我的目标 c 几乎可以忽略不计。 我没有找到任何与 cocos2dx 和 google 登录 相关的代码。 那里只有 swift 代码。

这是我做错的代码：

AppController.h 文件代码。

#import <GoogleSignIn/GoogleSignIn.h>

#import <GoogleSignIn/GoogleSignIn.h>

@class RootViewController;


@interface AppController : UIViewController <UIApplicationDelegate, GIDSignInDelegate , GIDSignInUIDelegate> {
    UIWindow *window;
    RootViewController* viewController;

Answer 1

“其视图不在窗口层次结构中！”问题几乎是由于：

您已经展示了视图控制器（但尚未展示）并尝试在其上方展示另一个视图。

Answer 2

您是否将AppController 添加到rootviewcontroller？错误信息清楚地抱怨它。
