IOS)Realm - Configuration & Extension Realm Share - 2

안녕하세요!

륵짭이 입니다.

이번에는 Realm을 다른 Extension에서 공용으로 사용할 수 있도록 하는 방법을 공유하려고 합니다.

후우,,, 개발은 왤케 공부할게 많은걸까요,,,

 

** ShareExtension을 만들자 ** 

일단 Extension을 추가해준다.

이렇게 해서 Extension을 추가를 해주고

 - Podfile에 추가 - 

target 'Realm-Config&Encryp' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for Realm-Config&Encryp
pod "RealmSwift"

target 'shareExtension' do
inherit! :search_paths
end

end

위에 처럼 추가 해준다.

inherit! :search_paths를 하면 위에 있는 pod 내용을 해당 target에서도 사용할 수 있도록 해준다.

 

** Extension에서 Realm 사용 ** 

import RealmSwift

class ShareViewController : UIViewController {

func accessMainRealm(){
        //Cannot Access
        print(#function)
        let config = Realm.Configuration(fileURL: inLibrarayFolder(fileName: "main.realm"))
        let realm = try! Realm(configuration: config)
        
        let airports = realm.objects(Airport.self)
        
        print("Airports in database = \(airports.count)")
        print(config.fileURL!)
        print("=====================")
    }
    
}

//결과
file:///Users/taesooyoon/Library/Developer/CoreSimulator/Devices/48103AEA-4A40-4AA1-B304-1766D4547117/data/Containers/Data/PluginKitPlugin/B369D9B6-129A-4536-83F5-36849182F5DD/Library/main.realm

이걸 보면 main.realm을 보면 

PluginKitPlugin

이 들어가서 이상한 곳을 가르키고 있습니다.

 

** App Group 등록하기 **

이렇게 앱 끼리 다른 현상이 있을 때, App Group을 통해서 서로 연결 시켤 줄 수 있습니다.

iOS ) Add the App Groups feature to your App ID.

안녕하세요. Today extension을 해볼까...해서 하는데(Today Extension 처음해봄..) ㅇ..?이게머얌 이건!! 나의 developer사이트에서 해결할 수 있습니다. 로 들어가셔서, 저는 App Groups을 생성해본적이 없으..

zeddios.tistory.com

이렇게 해주고 

앱 그룹을 추가해주고 원하는 App Group을 등록 해줍니다.

** Shared Realm 생성하기 **

    func shareRealm(){
        print(#function)
        let directory = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.taesoo.shareExtension.Share")?.appendingPathComponent("shared.realm")
        let sharedConfig = Realm.Configuration(fileURL: directory)
        if let bundleUrl = Bundle.main.url(forResource: "bundle", withExtension: "realm") {
            if !FileManager.default.fileExists(atPath: directory!.path) {
                try! FileManager.default.copyItem(at: bundleUrl, to: sharedConfig.fileURL!)
                print(sharedConfig.fileURL!)
            }
            else{
                print("file exist")
            }
        }
        print("==========================")
    }

위와 같이 FileManager의 forSecurityApplicationGroupIndentifier를 통해서 

AppGroup 이름을 적어주고 Realm Configuration을 생성해줍니다.

그리고 기본을 생성한 Bundle.Realm을 그대로 복사한 후에는

해당 Path에 Realm 파일을 생성이 됩니다.

그럼 이제 원래 App 에서도 접근 할 수 있도록 

똑같이  아래 코드를 넣어줍니다.

class ViewController: UIViewController {

func shareRealm(){
        print(#function)
        let directory = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.taesoo.shareExtension.Share")?.appendingPathComponent("shared.realm")
        let sharedConfig = Realm.Configuration(fileURL: directory)
        
        if FileManager.default.fileExists(atPath: directory!.path) {
            let realm = try! Realm(configuration: sharedConfig)
            let airports = realm.objects(Airport.self)
            print(sharedConfig.fileURL!)
            print(airports.count)
            self.label.text = "\(airports.count)"
        }
        else{
            print("file exist")
        }
        
        print("==========================")
    }
    
}
