我正在使用Swift构建iOS来共享位置。有没有人知道如何使用Geofire与Swift存储一个模拟器的位置,然后在另一个模拟器中显示存储的位置?
非常感谢。

首先尝试使用如下的cocopod,
pod 'Firebase', '~>4.0'
pod 'Firebase/Auth'
pod 'Firebase/Database'
pod 'Firebase/Storage'
pod 'GeoFire', :git => 'https://github.com/firebase/geofire-objc.git'
使用以下代码设置并从Geofire获取位置。
struct FndDatabase {
static let LOCATION = Database.database().reference().child("userlocation")
static let GEO_REF = GeoFire(firebaseRef: LOCATION)
}
func setUserLocation(location: CLLocation) {
let user = Auth.auth().currentUser?.uid //userid for the logged in user
if let uid = user {
FndDatabase.GEO_REF?.setLocation(location, forKey: uid)
}
}
func getLocation() -> CLLocation? {
var loc: CLLocation?
if let uid = Auth.auth().currentUser?.uid {
FndDatabase.GEO_REF?.getLocationForKey(uid, withCallback: { (location, err) in
if err != nil {
print( "Error getting Userlocation from Geofire \(err.debugDescription)")
} else {
print( "UserLocation is available \(location.debugDescription)")
loc = location
}
})
}
return loc
}
如果您发现此错误,请' FirebaseDatabase / FirebaseDatabase.h'找不到文件。
然后执行此操作,从pod中选择FirebaseDatabase.framework并将其链接到Geofire,如图所示
