ios 8 条推送通知未向我显示当前应用的徽章

Question

你好朋友，我是推送通知的新手，请帮助我。我正在尝试为我的应用程序获取徽章计数，但 "NSDictionary userInfo" 仅包含 alert 和 sound 。这是推送通知注册设备的代码

  -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{
 if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
{
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge |UIUserNotificationTypeAlert |  UIUserNotificationTypeSound categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
}

现在
当我从服务器收到消息时。

 -(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];
        }
    }
        application.applicationIconBadgeNumber =[[[userInfo objectForKey:@"aps"] objectForKey: @"badge"]integerValue];

    if (userInfo)
    {
        NSLog(@"%@",userInfo);

        if ([userInfo objectForKey:@"aps"])
        {
            if([[userInfo objectForKey:@"aps"] objectForKey:@"badgecount"])
            {
                [UIApplication sharedApplication].applicationIconBadgeNumber = [[[userInfo objectForKey:@"aps"] objectForKey: @"badgecount"] intValue];
            }
        }
    }

    }

现在输出是

{ aps =     
    {
        alert = "MAgic 2 SAlon App!";
        sound = default;
    };
}

我的 php 代码是 `

// Put your device token here (without spaces):
$deviceToken = 'xxxxxxxxx';

// Put your private key's passphrase here:
$passphrase = 'xxxxxx';

// Put your alert message here:
$message = 'xxxxxxx!'; 

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

// Open a connection to the APNS server
$fp = stream_socket_client(
'ssl://gateway.sandbox.push.apple.com:2195', $err,
$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

if (!$fp)
exit("Failed to connect: $err $errstr" . PHP_EOL);

echo 'Connected to APNS' . PHP_EOL;

// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => 'default'
);

// Encode the payload as JSON
$payload = json_encode($body);

// Build the binary notification
 $msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n',  strlen($payload)) . $payload;

// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));

if (!$result)
echo 'Message not delivered' . PHP_EOL;
else
echo 'Message successfully delivered' . PHP_EOL;

// Close the connection to the server
fclose($fp);`

到目前为止，您的 iOS 代码没有问题，但在您的 php 脚本中，您缺少徽章计数。

在所有 iOS 个应用中，未读通知计数从 backend/server 开始维护。当 backend/server 向特定设备发送推送通知时，服务器会发送徽章计数以及有效负载。

所以我猜后端没有向您发送徽章计数。

backend/server 团队应遵循此格式，以便您可以通过编程方式获取徽章计数：-

{
    "aps" :  
    {
        "alert" : "msg",
        "badge" : 1 ,
        "sound" : "demo.aiff"
    }
}
