推送通知applicationIconBadgeNumber在ios7中未更新

Question

我在應用程序委托中使用以下代碼來接收遠程通知，但是當應用程序在后台運行時，其applicationIconBadgeNumber（以紅色/白色顯示在應用程序圖標的左上角）不會更新。 當推送通知收到時，它以幻燈片動畫的形式出現在屏幕的右上角，通知有效負載中的徽章計數正好來自服務器端。

在didFinishLaunchingWithOptions我輸入了以下代碼

[application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];

遠程通知代表：

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    NSString *deviceTokenTrimmed = [[[[deviceToken description]
                                      stringByReplacingOccurrencesOfString:@"<"withString:@""]
                                     stringByReplacingOccurrencesOfString:@">" withString:@""]
                                    stringByReplacingOccurrencesOfString: @" " withString: @""];
    currentdeviceToken=deviceTokenTrimmed;
    [[NSUserDefaults standardUserDefaults] setValue:deviceTokenTrimmed forKey:@"pushtoken"];
    NSLog(@"Device Token didRegisterForRemoteNotificationsWithDeviceToken :  %@",deviceTokenTrimmed);

}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"Device Token in FailToRegister RemoteNotifications ERROR %@",error);
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    NSLog(@"%@",userInfo);
    if (application.applicationState == UIApplicationStateActive)
    {
        /***********code to show alert********/
        if (![[[NSString alloc]initWithString:[[userInfo objectForKey:@"aps"] objectForKey: @"alert"]] isEqualToString:@""] && [[NSString alloc]initWithString:[[userInfo objectForKey:@"aps"] objectForKey: @"alert"]]!=nil) {
            NSString *MSG =[[NSString alloc]initWithString:[[userInfo objectForKey:@"aps"] objectForKey: @"alert"]];
            UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Message" message:MSG delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil, nil];
            [alert show];
        }else{
            UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Message" message:@"Notification Received." delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil, nil];
            [alert show];
        }
    }else{
      application.applicationIconBadgeNumber =[[[userInfo objectForKey:@"aps"] objectForKey: @"badge"]integerValue];
    }

}

提前致謝。

我發現了sol，實際上是application：didReceiveRemoteNotification在后台應用程序時未調用，在后台運行app時，它有責任更新applicationIconBadgeNumber，在我的情況下，實際問題出在有效載荷中。 從服務器端將其設置為字符串，但應為整數。 我正在發布用php編寫的有效載荷正確代碼。

// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => 'sound.caf',
'badge' => $badge_count // Should be int type
);

謝謝，mokujin和Himanshu

UIApplicationDelegate使用方法

由於application:didReceiveRemoteNotification:方法僅在應用程序處於活動狀態時運行，因此無論應用程序的狀態如何，系統都會調用此方法。

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary*)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {

       NSInteger badgeNumber = [application applicationIconBadgeNumber];
       [application setApplicationIconBadgeNumber:++badgeNumber];

    }

如果您實際上是在設置JSON數字，請設置徽章編號。 唯一的解決方案是通過在每次讀取“通知”時通知服務器來管理服務器端。

我給出了一個邏輯，即如何在Google中實現搜索，與此相關的文章很多。
