화면 만들기

통지 상태를 좋은 느낌으로 취득해 주는 클래스의 작성

import RxSwift
import RxCocoa
import UserNotifications

class RxNotificationCenter {
    static let shared = RxNotificationCenter()

    let authorizationStatus = PublishRelay<UNAuthorizationStatus>()

    private init() {}

    func updateAuthorizationStatus() {
        // 通知設定状態を取得し、オブザーバに流す
        UNUserNotificationCenter.current().getNotificationSettings { [weak self] settings in
            self?.authorizationStatus.accept(settings.authorizationStatus)
        }
    }
}

알림 꺼져요 표지보기 만들기

class DisableNotificationCoverView: UIView {

    @IBOutlet weak var openNotificationSettingButton: UIButton!

    private let disposeBag = DisposeBag()

    override init(frame: CGRect) {
        super.init(frame: frame)
        commonInit()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        commonInit()
    }

    override func awakeFromNib() {
        openNotificationSettingButton.rx.tap
            .subscribe(onNext: { [weak self] in
                // ボタンがタップするたびにここの処理が呼ばれる
                if let url = URL(string: UIApplicationOpenSettingsURLString), UIApplication.shared.canOpenURL(url) {
                    // 本体設定のこのアプリの設定画面を開く処理
                    UIApplication.shared.open(url, options: [:], completionHandler: nil)
                }
            })
            .disposed(by: disposeBag)
    }

    private func commonInit() {
        let bundle = Bundle(for: type(of: self))
        let nib = UINib.init(nibName: "DisableNotificationCoverView", bundle: bundle)
        let view = nib.instantiate(withOwner: self, options: nil).first as! UIView
        self.addSubview(view)
    }
}

알림 설정 화면

import UIKit
import UserNotifications
import RxSwift

class ViewController: UIViewController {

    @IBOutlet weak var disableNotificationCoverView: UIView!

    private let disposeBag = DisposeBag()

    override func viewDidLoad() {
        super.viewDidLoad()
        navigationItem.title = "通知設定"
        setupViewController()
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        // 通知設定状態を取得させてオブザーバに流すように命令
        RxNotificationCenter.shared.updateAuthorizationStatus()
    }

    private func setupViewController() {
        // RxNotificationCenterの通知設定状態のオブザーバを監視、変更があったらUIを変更する
        RxNotificationCenter.shared.authorizationStatus
            .map { status -> Bool in
                switch status {
                case .authorized:
                    return true
                case .denied, .notDetermined:
                    return false
                }
            }
            .bind(to: disableNotificationCoverView.rx.isHidden)
            .disposed(by: disposeBag)
        // 通知設定状態を取得させてオブザーバに流すように命令
        RxNotificationCenter.shared.updateAuthorizationStatus()
    }
}

마지막으로 알림 설정 화면에서 앱으로 돌아올 때 알림 설정 상태를 얻습니다.

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    func applicationWillEnterForeground(_ application: UIApplication) {
        RxNotificationCenter.shared.updateAuthorizationStatus()
    }

}
