ios - 'GIDSignIn' 没有可见的@interface 声明选择器'handleURL:

Question

我在目标 C 中实现了 Google SignIn 的委托方法。但出现以下错误Error - No visible @interface for 'GIDSignIn'

- (BOOL)application:(UIApplication *)app
            openURL:(NSURL *)url
            options:(NSDictionary<NSString *, id> *)options{

    return [[GIDSignIn sharedInstance] handleURL:url];

}

Answer 1

更改自：

[[GIDSignIn sharedInstance] handleURL:url
                sourceApplication:sourceApplication
                       annotation:annotation];

至：

[[GIDSignIn sharedInstance] handleURL:url];

Answer 2

替换它并重试一次，参考：谷歌登录快速迁移指南

  [[GIDSignIn sharedInstance] handleURL:url sourceApplication:sourceApplication annotation:annotation];

完整答案

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

return [[GIDSignIn sharedInstance] handleURL:url sourceApplication:sourceApplication annotation:annotation];

}
