没有收到推送通知企业应用程序

Question

我已经创建了一个企业帐户的应用程序，它为几个员工，.pem证书已上传到服务器，但我仍然没有收到任何推送通知，知道添加了所有功能和代表，但没有收到。应用程序询问用户是否要接收推送通知，我们按下＆＃34;允许＆＃34;，令牌已发送到服务器，已调用didRegisterForRemoteNotifications，沙箱设置为1（开发），但没有收到

@interface AppDelegate ()<CLLocationManagerDelegate,UNUserNotificationCenterDelegate>
.
.
.
+ (void)registerPushNotifications {
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
.
.
.
}

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