问题 I want to observe the property UITextfield.editing . I'm using this code: self.money.rx_observe(Bool.self, "editing").subscribeNext { (value) in print("") }.addDisposableTo(disposeBag) But in the process of running, it's only performed once. How do I solve this，please 回答1: Don't observe the editing property, because it's not just a stored property. It's defined as: public var editing: Bool { get } So you don't know how UIKit is actually getting that value. Instead, use rx.controlEvent and

问题 We're trying to use Swift structs where we can. We are also using RxSwift which has methods which take closures. When we have a struct that creates a closure that refers to self , that creates a strong reference cycle. import Foundation import RxSwift struct DoesItLeak { var someState: String = "initial value" var someVariable: Variable<String> = Variable("some stuff") let bag = DisposeBag() mutating func someFoo() { someVariable.subscribeNext { person in self.someState = "something" }

问题 I master RxSwift and when using RxDataSource, the SearchBar delegates do not work for me and he, I can’t see the error. Without RxDataSource everything works, on other screens I have no problems. Tell me, with a fresh look, what is the mistake? why doesn't the filter happen? private var defaultCategories: [Groups]! var groupsCoreData = BehaviorRelay<[Groups]>(value: []) override func viewDidLoad() { super.viewDidLoad() searchBarRx() tableViewRx() } let dataSource =

问题 I'm quite new to RX and I'm trying to understand how I can continue a task, after an error which requires user input. A concrete example would be two factor authentication.. We have an auth-service and a protected resource. Logging in, we receive from the auth-service a LOA-2 (username&password used) token. trying to fetch data from the protected resource we receive an error stating we need LOA-3 (two-factor). So we have to get the input from the user, send it to the auth-service, get a new

问题 I have a big concern about how to manage object properties changes. Imagine I have a "car" class, with some properties like "name", "date", "price" etc. In my view "A", I'm displaying all cars I retrieve from a API. In a view B & C, I can display and edit specific information about the car selected in the view A (let's say it's "car AAA"). it's possible too, to refresh the car object with a API call to retrieve the last information about the car. I want to be able to update the view A, if the

问题 I have a problem with implementing a UITableView using RxSwift. I tried to bind an observable of an array of models to the table items with the following code. models.bind(to: self.tableView.rx.items(cellIdentifier: "Cell", cellType: ModelTableViewCell.self . But when I do it gives me the following error: Type 'inout UITableView' does not conform to protocol 'ReactiveCompatible' and I know the error can't be right because NSObject extends ReactiveCompatible so UITableView also does. Also, my

问题 I try to migrate delegate of SRWebSocket to observable. This is my RxSocketManagerDelegateProxy.swift: class RxSocketManagerDelegateProxy: DelegateProxy, DelegateProxyType{ static func currentDelegateFor(object: AnyObject) -> AnyObject?{ let socket: SRWebSocket = object as! SRWebSocket return socket.delegate } static func setCurrentDelegate(delegate: AnyObject?, toObject object: AnyObject) { let socket: SRWebSocket = object as! SRWebSocket socket.delegate = delegate as? SRWebSocketDelegate }

问题 I have a sequence made up of multiple operators. There are total of 7 places where errors can be generated during this sequence processing. I'm running into an issue where the sequence does not behave as I expected and I'm looking for an elegant solution around the problem: let inputRelay = PublishRelay<Int>() let outputRelay = PublishRelay<Result<Int>>() inputRelay .map{ /*may throw multiple errors*/} .flatmap{ /*may throw error*/ } .map{} .filter{} .map{ _ -> Result<Int> in ...} .catchError

问题 I have a pretty hefty chunk of chained Rx observables that are fired when a tableviews row is selected via table.rx.modelSelected . I'd like to be able to break this logic up, because I'm currently having to execute business logic in flatMapLatest , because it's "Step 1" to the process (which feels wrong), and I have to execute more business logic in the subsequent subscribe ("Step 2"). Here's the code I'm using: locationsTable.rx.modelSelected(Location.self) .flatMapLatest { [weak self]

问题 In my OS X status bar app I'm using interval function to periodically call an external api and display the result: Observable<Int> .interval(120.0, scheduler: MainScheduler.instance) .startWith(-1) // to start immediately .flatMapLatest(makeRequest) // makeRequest is (dummy: Int) -> Observable<SummaryResponse?> .subscribeNext(setSummary) .addDisposableTo(disposeBag) However, if user changes the preferences in the meantime, I would like to "restart" this interval and make a new call
