问题 I'm using RxSwift to bind a model array to a collection view How do I get the model object from a given indexPath? I'm doing the binding like this: vm.bikeIssueCatagories() .drive(self.collectionView.rx.items(cellIdentifier: "BikeIssueCategoryCollectionViewCell", cellType: UICollectionViewCell.self)) { row, data, cell in }.disposed(by: disposeBag) The core of my issue is, that I need to get both the model object and the cell that a user selects. Using collectionView.rx.modelSelected(T.self)

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 I would like to have a UITextField configured with RxSwift/RxCocoa so that it only contains up to ... characters. I do not want to use the UITextFieldDelegate for this but would love to achieve this with RxSwift/RxCocoa. Is there a way to do this? 回答1: Sure: textField.rx.controlEvent(.editingChanged).subscribe(onNext: { [unowned self] in if let text = self.textField.text { self.textField.text = String(text.prefix(40)) } }).disposed(by: disposeBag) In this example, the textfield is limited to

问题 I have a simple test project with a UINavigationController as my rootViewController . I push the first ViewController which has a + button as right bar button item, I subscribe to its taps to present a new ViewController (which is identical to the previous one). The push segue works as I expect. UIKit manages the back button for me and I think it is UINavigationController that makes the magic behind the scene. Now, what I need to do is subscribe to the back button, but I can't find how to do

问题 I have a view controller with UITableView.

问题 I'm new to RxSwift and I have this code to setup a tableview which contains a textfield: budget.expenses.asObservable() .bindTo(tableView.rx.items(cellIdentifier: ExpenseInputCell.cellIdentifier, cellType: ExpenseInputCell.self)){(row, element, cell) in cell.name.text = element.name.value cell.name.rx.text .bindTo(element.name) .addDisposableTo(self.disposeBag) } .addDisposableTo(disposeBag) tableView.rx.itemDeleted .subscribe(onNext: {indexPath in self.budget.expenses.value.remove(at:

问题 I am trying to detect if a observable(my case button.rx.tap ) has not emitted any value for say like 3 seconds. If yes, I would like to update the user interface. Here is my attempt so far: Observable<Int>.interval(3, scheduler: MainScheduler.instance) .takeUntil(button.rx.tap) // I know take until will stop the timer sequence .subscribe({ event in print(event) UIView.animate(withDuration: 0.4, animations: { if let number = event.element { let scale: CGFloat = number % 2 == 0 ? 1.5 : 1.0 self
