选择器‘handleURL’声明的'GIDSignIn‘没有可见的@接口：

Question

我在objective C中实现了谷歌SignIn的委托方法，但我得到了下面的错误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

替换它，然后重试一次，引用：Google Sign-In quick migration guide

  [[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];

}

Answer 2

更改自：

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

至：

[[GIDSignIn sharedInstance] handleURL:url];
