使用id列表的Firebase查询(iOS)-Firebasequeryusingalistofids(iOS)

No, you can't do a batch query like that in Firebase.

不，您不能在Firebase中执行这样的批处理查询。

You will need to loop over your restaurant IDs and query each one using observeSingleEvent. For instance:

您将需要对您的餐厅id进行循环，并使用observeSingleEvent查询每个id。例如:

let restaurantIDs: NSArray = ...
let db = FIRDatabase.database().reference()
for id in restaurantIDs as! [String] {
    db.child("Restaurants").child(id).observeSingleEvent(of: .value) {
        (snapshot) in
        let restaurant = snapshot.value as! [String: Any]
        // Process restaurant...
    }
}

If you are worried about performance, Firebase might be able to group all these observeSingleEvent calls and send them as a batch to the server, which may answer your original question after all ;-)

如果您对性能感到担忧，Firebase可能会将所有这些observeSingleEvent调用分组，并将它们作为批处理发送给服务器，这可能最终会回答您最初的问题;
