ios - 如何禁用 iOS 远程通知的默认通知警报 View ？

Question

在我的应用中我启用了远程通知，

if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"10.0")){
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
        if( !error ){
            [[UIApplication sharedApplication] registerForRemoteNotifications];
        }
    }];
}else{
    UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound);
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes categories:nil];
    [application registerUserNotificationSettings:settings];
    [application registerForRemoteNotifications];
}

我按如下方式实现了委托(delegate)方法，

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{
    NSLog(@"Failed!!");
}


 - (void)application:(UIApplication *)application   didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    // Print message.
    if (userInfo) {
        NSLog(@"Message ID: %@", userInfo);
    }

    completionHandler(UIBackgroundFetchResultNoData);
}

但是当应用程序处于前台并收到通知时，我得到了一个带有通知标题和消息的 UIAlertView。我要

//Called when a notification is delivered to a foreground app.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
    NSLog(@"User Info : %@",notification.request.content.userInfo);
    completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionBadge);
}

//Called to let your app know which action was selected by the user for a given notification.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center       didReceiveNotificationResponse:(UNNotificationResponse *)response    withCompletionHandler:(void(^)())completionHandler{
    NSLog(@"User Info : %@",response.notification.request.content.userInfo);
    completionHandler();
}

我在 willPresentNotification: 上进行了调试，在触发之后我收到了警报。我也通过删除此方法进行了测试。但是当收到通知时仍然显示此警报。

如何禁用此警报 View ？我在我的 iPhone 中使用 10.2 iOS

我不认为 UIAlertController 来自通知。您确定您没有在别处创建一个吗？

您的通知实现似乎没问题。

您能否在您的项目中搜索并使用断点来查看是否有任何 UIAlertController 被命中？
