如何在 iOS Objective-c 中实现交互式远程通知

Question

我是 Objective-c 的新手。我想创建一个交互式远程通知，它有两个动作，一个是调用“OK”，另一个是调用“VIEW”。当用户通过 APNS 收到通知时，如果用户单击“确定”，则必须关闭通知，并且如果用户单击“查看”，则该时间打开我的应用程序的特定页面。就是这样。

我浏览了许多网络文档并掌握了一些通知负载的概念。但我无法明智地实施这一步。任何人都可以帮助我，我该如何实现这个功能。并且请任何人不要标记为重复的问题。谢谢

注意：我在这里使用了我自己的常量，比如KNotificatoin_IDENTIFIER_CATEGORY_NEW_BID 在那个地方使用你的

注册推送

- (void) registerPushNotification {

    UIUserNotificationType  type = UIUserNotificationTypeAlert | UIUserNotificationTypeBadge |  UIUserNotificationTypeSound;
    UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:type categories:[NSSet setWithObjects:[self createActionNotificationsSettingForApproveBID],[self createActionNotificationsSettingForCancelingRequest ], nil]];
    [[UIApplication sharedApplication] registerUserNotificationSettings:setting];
    [[UIApplication sharedApplication] registerForRemoteNotifications];

}


- (UIMutableUserNotificationCategory *) createActionNotificationsSettingForApproveBID {

    UIMutableUserNotificationAction *actionApproveBID = [[UIMutableUserNotificationAction alloc]  init];
    [actionApproveBID setIdentifier:KNotificatoin_IDENTIFER_ACTION_APPROVEBID];
    actionApproveBID.activationMode = UIUserNotificationActivationModeForeground;
    actionApproveBID.title = @"Approve";
    actionApproveBID.authenticationRequired = true;
    [actionApproveBID setDestructive: false];


    UIMutableUserNotificationAction *actionCancelDialog = [[UIMutableUserNotificationAction alloc]  init];
    [actionCancelDialog setIdentifier:KNotificatoin_IDENTIFER_ACTION_DETAILS];
    actionCancelDialog.activationMode = UIUserNotificationActivationModeForeground;
    actionCancelDialog.title = @"Details";
    actionCancelDialog.authenticationRequired = true;
    [actionCancelDialog setDestructive: false];

    UIMutableUserNotificationCategory *cateogoryApproveBID = [[UIMutableUserNotificationCategory alloc] init];
    cateogoryApproveBID.identifier = KNotificatoin_IDENTIFIER_CATEGORY_NEW_BID;
    [cateogoryApproveBID setActions:@[actionApproveBID,actionCancelDialog] forContext:UIUserNotificationActionContextDefault];
    [cateogoryApproveBID setActions:@[actionApproveBID,actionCancelDialog] forContext:UIUserNotificationActionContextMinimal];

    return cateogoryApproveBID;
}

- (UIMutableUserNotificationCategory *) createActionNotificationsSettingForCancelingRequest {

    UIMutableUserNotificationAction *actionGetMoreBids = [[UIMutableUserNotificationAction alloc]  init];
    [actionGetMoreBids setIdentifier:KNotificatoin_IDENTIFER_ACTION_APPROVEBID];
    actionGetMoreBids.activationMode = UIUserNotificationActivationModeForeground;
    actionGetMoreBids.title = @"Get more bids";
    actionGetMoreBids.authenticationRequired = true;
    [actionGetMoreBids setDestructive: false];


    UIMutableUserNotificationAction *actionEditRequest = [[UIMutableUserNotificationAction alloc]  init];
    [actionEditRequest setIdentifier:KNotificatoin_IDENTIFER_ACTION_EDIT_REQUEST];
    actionEditRequest.activationMode = UIUserNotificationActivationModeForeground;
    actionEditRequest.title = @"Edit request";
    actionEditRequest.authenticationRequired = true;
    [actionEditRequest setDestructive: false];

    UIMutableUserNotificationCategory *categoryCancelRequest = [[UIMutableUserNotificationCategory alloc] init];
    categoryCancelRequest.identifier = KNotificatoin_IDENTIFER_ACTION_MORE_BIDS;
    [categoryCancelRequest setActions:@[actionGetMoreBids,actionEditRequest] forContext:UIUserNotificationActionContextDefault];
    [categoryCancelRequest setActions:@[actionGetMoreBids,actionEditRequest] forContext:UIUserNotificationActionContextMinimal];

    return categoryCancelRequest;
}

你将如何处理动作？

- (void) application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void (^)())completionHandler {
    NSLog(@" APPLICATION STATUS %ld",(long)[UIApplication sharedApplication].applicationState);

    if ([[[userInfo objectForKey:@"aps"] objectForKey:kCategory] isEqualToString:KNotificatoin_IDENTIFIER_CATEGORY_NEW_BID]){
        if ([identifier isEqualToString:KNotificatoin_IDENTIFER_ACTION_APPROVEBID]) {
            NSMutableDictionary *dictData = [NSMutableDictionary dictionaryWithDictionary:userInfo];
            [dictData setObject:@17 forKey:kType];

            if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive || self.isApplicationIsInActiveState) {
                [self saveDictionaryForPushActiveState:dictData];
            } else {
                [self navigatateAsPerPush:dictData allowInActiveState:NO];
            }
        }
        else if ([identifier isEqualToString:KNotificatoin_IDENTIFER_ACTION_DETAILS]) {
            NSLog(@"You chose action 2.");
            if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive || self.isApplicationIsInActiveState) {
                [self saveDictionaryForPushActiveState:userInfo];
            } else {
                [self navigatateAsPerPush:userInfo allowInActiveState:NO];
            }
        }
    } else  if ([[[userInfo objectForKey:@"aps"] objectForKey:kCategory] isEqualToString:KNotificatoin_IDENTIFIER_NOTIFICATION_REQUEST]){

        NSMutableDictionary *dictData = [NSMutableDictionary dictionaryWithDictionary:userInfo];

        if ([identifier isEqualToString:KNotificatoin_IDENTIFER_ACTION_EDIT_REQUEST]) {
            NSLog(@"You chose action 1.");
            [dictData setObject:@16 forKey:kType];
            if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive || self.isApplicationIsInActiveState) {
                [self saveDictionaryForPushActiveState:dictData];
            } else {
                [self navigatateAsPerPush:dictData allowInActiveState:NO];
            }

        }
        else if ([identifier isEqualToString:KNotificatoin_IDENTIFER_ACTION_MORE_BIDS]) {
            NSLog(@"You chose action 2.");
            if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive || self.isApplicationIsInActiveState) {
                [self saveDictionaryForPushActiveState:dictData];
            } else {
                [self navigatateAsPerPush:dictData allowInActiveState:NO];
            }

        }

    }

    if (completionHandler) {
        completionHandler();
    }
}

希望对你有帮助

借助 iOS 12 SDK，您的应用可以利用 通知中的交互式控件

通知内容应用扩展现在支持自定义视图中的用户交互。如果您的应用通知的内容需要提示用户交互，请添加按钮和开关等控件。

启用用户交互：

打开通知内容扩展的 info.plist 文件。

将 UNNotificationExtensionUserInteractionEnabled 键添加到您的扩展属性。给它一个布尔值，设置为 YES。
