UITableView Cell中的通知徽章

Question

目前我的應用程序收到有關RSS提要更新的通知。如果用戶從通知中打開應用程序，它將打開到正確的視圖控制器。如果用戶不確認通知並從應用程序圖標打開應用程序，則當用戶在應用程序內打開菜單時，該rss供稿的表格視圖單元格帶有帶有applicationIconBadgeNumber的徽章圖標。選中該行後，該單元格上的徽章將消失，並重置applicationIconBadgeNumber。我的問題是關於想要發送有關應用內其他信息的通知，如會員優惠。我如何區分表視圖中的哪一行獲得徽章？假設用戶收到關於會員福利的通知。我希望徽章出現在表格視圖的成員權益行中，但是如果有來自RSS提要的通知，請標記適當的行。

這是我目前如何爲RSS提要行添加徽章。

在didSelectRowAtIndexPath方法

if (!(indexPath.row == 0)) 
    { 
     cell.accessoryView = nil; 
    } 

    badgeNumber = [NSString stringWithFormat:@"%ld", (long)[[UIApplication sharedApplication]applicationIconBadgeNumber]]; 

    actionAlertBadge = [JSCustomBadge customBadgeWithString:badgeNumber withStringColor:[UIColor whiteColor] withInsetColor:[UIColor redColor] withBadgeFrame:NO withBadgeFrameColor:[UIColor redColor] withScale:1.0 withShining:NO withShadow:NO]; 
    actionAlertBadge.frame = CGRectMake(83, 6, 30, 30); 

    if ([badgeNumber isEqualToString:@"0"]) 
    { 
     actionAlertBadge.hidden = YES; 
    } 

    if (actionAlertBadge.hidden == NO) 
    { 
     if (indexPath.section == 0) 
     { 
      if (indexPath.row == 0) 
      { 
       cell.accessoryView = actionAlertBadge; 
      } 
     } 
    } 

：

中的cellForRowAtIndexPath

if (indexPath.row == 0) 
     { 
      ActionAlertsViewController *actionAlerts = [[ActionAlertsViewController alloc]initWithStyle:UITableViewStylePlain]; 
      WebViewController *wvc = [[WebViewController alloc]init]; 
      [actionAlerts setWebViewController:wvc]; 
      [[UAPush shared] resetBadge]; 
      actionAlertBadge.hidden = YES; 
      [tableView reloadData]; 
      navController = [[KFBNavControllerViewController alloc]initWithRootViewController:actionAlerts]; 

      [UIView transitionWithView:appDelegate.window 
           duration:0.5 
           options:UIViewAnimationOptionTransitionFlipFromRight 
          animations:^{ 
           appDelegate.window.rootViewController = navController; 
          } 
          completion:nil]; 
     } 

編輯：這裏是我正在努力做到這一點，但它不工作，因爲在我的表視圖我notificationType串空值。

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo 
{ 
    UA_LINFO(@"Received remote notification: %@", userInfo); 

    // Send the alert to UA so that it can be handled and tracked as a direct response. This call 
    // is required. 
    [[UAPush shared]appReceivedRemoteNotification:userInfo applicationState:application.applicationState]; 

    // Optionally provide a delegate that will be used to handle notifications received while the app is running 
    // [UAPush shared].delegate = your custom push delegate class conforming to the UAPushNotificationDelegate protocol 

    // Reset the badge after a push received (optional) 
    [[UAPush shared] resetBadge]; 

    NSDictionary *apsInfo = [userInfo valueForKey:@"aps"]; 

    NSString *alertMsg = @""; 

    if ([apsInfo valueForKey:@"alert"] != NULL) { 
     alertMsg = [apsInfo valueForKey:@"alert"]; 

     if ([alertMsg containsString:@"ACTION ALERT"]) { 
      notificationType = @"action alert"; 
     } 
     else if ([alertMsg containsString:@"MEMBER BENEFIT"]) { 
      notificationType = @"member benefit"; 
     } 
    } 
} 

的cellForRowAtIndexPath：

KFBAppDelegate *appDelegate = (KFBAppDelegate *)[[UIApplication sharedApplication]delegate]; 
    NSString *notificationType = appDelegate.notificationType; 
    // NSLog(@"notificationType menu table: %@", notificationType); 
    badgeNumber = [NSString stringWithFormat:@"%ld", (long)[[UIApplication sharedApplication]applicationIconBadgeNumber]]; 
    actionAlertBadge = [JSCustomBadge customBadgeWithString:badgeNumber withStringColor:[UIColor whiteColor] withInsetColor:[UIColor redColor] withBadgeFrame:NO withBadgeFrameColor:[UIColor redColor] withScale:1.0 withShining:NO withShadow:NO]; 
    actionAlertBadge.frame = CGRectMake(83, 6, 30, 30); 

    if ([badgeNumber isEqualToString:@"0"]) { 
     actionAlertBadge.hidden = YES; 
    } 

    if (actionAlertBadge.hidden == NO) { 
     if ([notificationType isEqualToString:@"action alert"]) { 
      if (indexPath.section == 0) { 
       if (indexPath.row == 0) { 
        cell.accessoryView = actionAlertBadge; 
       } 
      } 
     } 
     else if ([notificationType isEqualToString:@"member benefit"]) { 
      if (indexPath.section == 0) { 
       if (indexPath.row == 5) { 
        cell.accessoryView = actionAlertBadge; 
       } 
      } 
     } 
    } 

Answer 1

首先，在發送的通知，您應在通知中添加類型的字段。你會得到JSON字典這樣

{"aps":{"alert":{"type":"rss","text":"Hello, world!"},"sound":"default","badge":3}} 

獲取函數的類型值（如果應用程序正在運行）

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary  *)dict {  
// get the type information out of the dictionary 
// now you can perform depending on this type. 
} 

如果應用程序沒有運行，然後根據apple's documentation

「如果在推送通知到達時應用程序沒有運行，該方法將啓動應用程序，並在啓動選項字典中提供相應的信息。應用程序不會調用此方法來處理該推送通知，而是執行應用程序：willFinishLaunchingWithOptions：或應用程序：didFinishLaunchingWithOptions：方法需要獲取推送通知有效載荷數據並進行適當的響應。

獲取您的字典在應用程序：didFinishLaunchingWithOptions：方法。

Answer 2

在AppDelegate中，先製作一個屬性：

@property (nonatomic, copy) NSString *notificationType; 

然後，在你

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo 

使用：

self.notificationType = @"action alert"; 
self.notificationType = @"member benefit"; 

，並在你的cellForRowAtIndexPath：

if (actionAlertBadge.hidden == NO) { 
    if ([appDelegate.notificationType isEqualToString:@"action alert"]) { 
     .... 
    } 
    else if ([appDelegate.notificationType isEqualToString:@"member benefit"]) { 
     .... 
    } 

在附註上，我建議儘量避免字符串比較，並使用類似枚舉的東西。
