ios - 'application :handleActionWithIdentifier:forRemoteNotification:completionHandler 实现中的参数类型冲突

Question

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void (^)(void))completionHandler {}

我收到了这个警告。有人可以告诉这里有什么问题吗？

Conflicting parameter types in implementation of 'application:handleActionWithIdentifier:forRemoteNotification:completionHandler:': 'void (^ _Nonnull __strong)()' vs 'void (^__strong _Nonnull)(void)'

Answer 1

一种解决方法是禁用 Clang 的 -Wstrict-prototypes，如下所示:

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wstrict-prototypes" 
completionHandler:(void(^)())completionHandler
#pragma clang diagnostic pop
{}

handleActionWithIdentifier:forLocalNotifications 也是如此。
这似乎是一个错误。
