使用通知中心在Realm Swift 3中保存UIButton更改状态

import RealmSwift

class ButtonState: Object {
    @objc dynamic var isButtonEnabled = true
}

let realm = try! Realm()
let buttonState = realm.objects(ButtonState.self).first

NotificationCenter.default.addObserver(forName: NSNotification.Name(rawValue: "ButtonStateChanged"), object: nil, queue: nil) { notification in
    // 处理按钮状态更改的逻辑
    // 例如，更新按钮的UI状态
    if let isEnabled = buttonState?.isButtonEnabled {
        button.isEnabled = isEnabled
    }
}

try! realm.write {
    buttonState?.isButtonEnabled = false
}

NotificationCenter.default.post(name: NSNotification.Name(rawValue: "ButtonStateChanged"), object: nil)
