问题 The Realm doc says the RLMResults are lick NSArray . I have some results returned from the database and I want to merge it into another RLMResults . But it seems it's immutable, How to make a RLMResults add objects from another RLMResults ? or make it mutable? or convert it to NSArray ? 回答1: Currently this is something you would have to do manually. You could create an RLMArray by concatenating your two results. We are discussing a union/merge method further down on the roadmap for RLMObjects

问题 On my API I've got a relationship between Stands and Products. In which stands have products, but products can be found in different stands aswell. I'm trying to replicate this relationship on my iOS-application, using Realm but I can't seem to get it working. The goal of having this relationship is being able to search for Stands that sell particular products. My model: class Stand: Object { dynamic var id : Int = 0 dynamic var name : String = "" dynamic var latitude : Double = 0.0 dynamic

This is what I've tried: let realm = try!

问题 I was just making a basic realm file using the latest REALM version but the compiler throws this error: An exception has occurred in the compiler (1.8.0). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade for duplicates.

问题 I am trying to download objects from Firebase and store them in Realm. I am receiving a crash when combining these two excellent libraries. I've created a very simple demo app which illustrates my problem. It seems Firebase gets upset when creating an object that extends RealmObject. I can make this work by removing the RealmObject extension but then I have to maintain two identical objects. Over time this becomes complicated and frustrating which is far from ideal. Firebase: FirebaseDatabase

问题 Im getting this error " Can only delete an object from the Realm it belongs to " every time I try to delete an object from realm on my tableview. Here is the relevant code: let realm = try! Realm() var checklists = [ChecklistDataModel]() override func viewWillAppear(_ animated: Bool) { checklists = [] let getChecklists = realm.objects(ChecklistDataModel.self) for item in getChecklists{ let newChecklist = ChecklistDataModel() newChecklist.name = item.name newChecklist.note = item.note

问题 How can I create an and operation with Realm? Example I have an object with day and month and I want to check both those fields values. Something like : RealmResults<Event> toEdit = realm.where(Event.class) .equalTo("day", day) .and .equalTo("month", month) .findAll(); But as far as I can tell there is no and operator. Thank you 回答1: Multiple conditions are combined with And unless there's an .or() between them, so it's just: RealmResults<Event> toEdit = realm.where(Event.class) .equalTo("day

问题 Realm supports encrypting the database file on disk with AES-256+SHA2 by supplying a 64-byte encryption key when creating a Realm. Since the Realm Mobile Platform is self hosted (inhouse or via cloud) - does that effectively also mean that this same database file encryption is available ? I'm assuming 'yes' but since I was always taught "never assume" I wanted to ask the question here. 回答1: Yes, the same encryption is also available for synched Realms. However, note that if you supply an
