iOS推送通知徽章編號超過圖標未顯示

Question

我在iPhone應用程序中已收到推送通知，但收到通知時，徽章編號未顯示在圖標上。當我單擊通知以打開應用程序並關閉它時，將顯示徽章。我的推送通知有效載荷格式為

{
    "aps" : {
        'alert' => $message,
    'sound' => 'default',
    'badge' => 1
    },
    'plsID' : '105',

}

我顯示徽章的代碼是

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

    for (id key in userInfo) {
        NSLog(@"key: %@, value: %@", key, [userInfo objectForKey:key]);

        [UIApplication sharedApplication].applicationIconBadgeNumber = [[[userInfo objectForKey:@"aps"] objectForKey: @"badge"] intValue];
    }
}

我面臨着同樣的問題。 我嘗試下面的代碼，並使其工作

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
