如何在iOS远程通知上禁用默认通知警报视图？

在我的应用程序中，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];
}

我实现了如下的委托方法

- (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);
}

但当应用程序在前台收到通知时，我得到了一个带有通知标题和消息的UIAlertView。我想

//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，触发后我收到了警报。我也通过移除这个方法进行了测试。但在收到通知时仍会显示此警报

如何禁用此警报视图？我在iPhone中使用10.2 iOS

我不认为

UIAlertController

来自通知。你确定你没有在其他地方创建吗

您的通知的实现似乎还可以

---

能否在项目中搜索并使用断点查看是否有任何

UIAlertController

s被命中？

在completionHandler中使用UNNotificationPresentationOptionNone

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
    NSLog(@"User Info : %@",notification.request.content.userInfo);
    completionHandler(UNNotificationPresentationOptionNone);
}

你说的禁用是什么意思？根本看不到警报？！你的意思是把它转换成无声的推动？是的。看不到警报。“你是说将其转换为无声推送？”是的。我不需要显示警觉，这很奇怪。好吧，当你在前景中时，你不应该看到警报。我不知道为什么会这样。你能不能用CMD+Shift+F（全球项目研究）来获取关于这个AlertView的每一条线索。例如，您可以搜索“initWithTitle:“Alert”或“message:“Alert”。为了找到这个AlertView，我做了。但是没有像这样的警报。你尝试过所有的警报控制器吗？我对他的答案作了修改。他以前在AlertView中使用过…@亲爱的，谢谢，这是个错误。
