我在Stackoverflow上发现了这个重复,但发布的答案对我不起作用：No sound in Parse push notification for ios8

>我已经检查了通知中心,并启用了消息和声音.
>创建了一个新的应用程序清洁版本
>检查其他推送消息是否在应用程序上发出声音
>使用Parse rest api并将声音设置为默认值.

我尝试过的所有事情都没有.

使用解析代码更新了我的应用：

// Register for Push Notitications,if running iOS 8
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                    UIUserNotificationTypeBadge |
                                                    UIUserNotificationTypeSound);
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
                                                                             categories:nil];
    [application registerUserNotificationSettings:settings];
    [application registerForRemoteNotifications];

} else {
    // Register for Push Notifications before iOS 8
    [application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |
                                                     UIRemoteNotificationTypeAlert |
                                                     UIRemoteNotificationTypeSound)];
}
