使用 python3.4 django 2.0.2

模型.py

class Userinfo(models.Model):

    useruid = models.BigAutoField(db_column='UserUID', primary_key=True)

    useremail = models.CharField(
            db_column='UserEmail', unique=True, max_length=100)
    userpassword = models.CharField(db_column='UserPassword', max_length=128)

    passwordsalt = models.CharField(db_column='PasswordSalt', max_length=128)
    userstatus = models.IntegerField(db_column='UserStatus', default=0)
    username = models.CharField(
        db_column='UserName', max_length=100, default=0)
    class Meta:
        managed = False
        db_table = 'userinfo'

class Postinfo(models.model):
    postuid = models.BigAutoField(db_column='PostUID', primary_key=True)
    content = content = models.TextField(db_column='Content')
    useruid = models.ForeignKey(
    Userinfo, db_column='UserUID', on_delete=models.CASCADE)

    class Meta:
         managed = False
         db_table = 'postinfo'

查询集

postquery = models.Postinfo.objects.all().select_related("useruid").order_by(
                '-postuid')

后查询是

<QuerySet [{'content': 'test','postuid': 1, 'useruid_id': 1},OtherPosts...> …

@Injectable()

var locMgr = INTULocationManager.sharedInstance()
    locMgr.requestLocation(withDesiredAccuracy: .city, timeout: 30, delayUntilAuthorized: true,block: {(currentLoc: CLLocation!, achievedAccuracy: INTULocationAccuracy, status: INTULocationStatus) -> Void in
        if status == INTULocationStatus.success {
        }
        else{
        }

二手INTULocationManager，Swift 4.1，iOS 11.1

如果是第一次运行此代码，则会弹出“位置许可请求”

但是如果我拒绝，则下次不会弹出。

如何打开权限弹出？

我创建按钮

运行此代码

let locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.requestWhenInUseAuthorization()

但没有用
