记录 ReactiveSwift 简单使用

1. 导入 ReactiveSwift 库
2. 创建 TestViewModel 文件

enum JKTypeType: Int {case cloudcase devicecase weater
}// 通过监听属性变化
class TestViewModel: NSObject {lazy var recordType: Property<JKTypeType> = {return Property(recordTypeProperty)}()private(set) var recordTypeProperty: MutableProperty<JKTypeType> = MutableProperty(.device)deinit {print("TestViewModel delloc")}
}extension TestViewModel {func setRecordType(_ type: JKTypeType) {recordTypeProperty.value = type}}

3. 使用 TestViewModel

class RegisterVC: UIViewController {var testViewModel =  TestViewModel()let disposes: CompositeDisposable = CompositeDisposable()override func viewDidLoad() {super.viewDidLoad()self.view.backgroundColor = UIColor.whitebindViewModel()}func bindViewModel() {disposes += testViewModel.recordType.signal.observeValues { type inprint("testViewModel: \(type)")}}@IBAction func backClick(_ sender: Any) {testViewModel.setRecordType(.cloud)}
}deinit {disposes.dispose()}
