标题: ios - 推送通知 applicationIconBadgeNumber 在 ios7 中未更新

我在应用程序委托(delegate)中使用以下代码接收远程通知，但其 applicationIconBadgeNumber(以红色/白色显示在应用程序图标的左上角)在后台应用程序时未更新。当收到推送通知时，它会以幻灯片动画出现在屏幕的上角，在通知有效负载中，角标(Badge)计数正在完美地从服务器端发出。

在 didFinishLaunchingWithOptions 我放了以下代码

[application registerForRemoteNotificationTypesUIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];

远程通知代表:

- (void)applicationUIApplication *)app didRegisterForRemoteNotificationsWithDeviceTokenNSData *)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)applicationUIApplication *)application didFailToRegisterForRemoteNotificationsWithErrorNSError *)error {
    NSLog(@"Device Token in FailToRegister RemoteNotifications ERROR %@",error);
}

- (void)applicationUIApplication *)application didReceiveRemoteNotificationNSDictionary *)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];
    }

}

提前致谢。

Best Answer-推荐答案

我找到了 sol，实际上 application:didReceiveRemoteNotification 应用程序在后台时没有调用，它的 os 负责在应用程序在后台时更新 applicationIconBadgeNumber， 就我而言，实际问题出在有效载荷中。从服务器端它被设置为字符串，但它应该是整数。我正在发布用 php 编写的有效载荷正确代码。

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