我如何在Geofire，Firebase中将用户吸引到我的位置附近 [英] How can i get user nearby my location in geofire,Firebase

问题描述

使用此代码，我从Geolocs中仅获取一个值，仅是键和位置，而不是附近的位置.

With this code, I am getting only one value from Geolocs just key and location, not a nearby location.What is wrong with it

var geoFireRef: DatabaseReference?
    var geoFire: GeoFire?
    var myQuery: GFQuery?


func Geofire() {

        geoFireRef = Database.database().reference().child("Geolocs")
    geoFire = GeoFire(firebaseRef: geoFireRef!)
        self.geoFire?.setLocation(currentLocation!, forKey:Auth.auth().currentUser!.uid)

    myQuery = geoFire?.query(at: currentLocation!, withRadius: 100)

    myQuery?.observe(.keyEntered, with: { (key, location) in


        if key != Auth.auth().currentUser?.uid
        {
            let ref = Database.database().reference().child("Users").child(key)

            ref.observeSingleEvent(of: .value, with: { (snapshot) in
                let id = snapshot.key
            })

        }

    })

}

推荐答案

将GeoFire位置与所有内容分开，并带有引用其他附加数据的键，例如用户信息或帖子信息.由于混合使用静态和动态数据并不是存储数据的最有效方法.

Keep your GeoFire Locations separate from everything with a key to reference the other additional data e.g. user info or post info. As mixing static and dynamic data would not be the most efficient way of storing the data.
