A UILabel is not configured with a tap gesture recognizer out of the box, that’s why RxCocoa does not provide the means to listen to a gesture directly on the label. You will have to add the gesture recognizer yourself. Then you can use Rx to observe events from the recognizer, like so: let disposeBag … Read more
You can use .merge() to combine the array of observables into a single observable, and then use .toArray() to get them as a list in a single event. For RxSwift 3+ use: let arrayOfObservables: [Observable<E>] = … let singleObservable: Observable<E> = Observable.from(arrayOfObservables).merge() let wholeSequence: Observable<[E]> = singleObservable.toArray() For previous versions: let arrayOfObservables: [Observable<E>] = … … Read more
Where you call subscribeOn() in a chain doesn’t really matter. Where you call observeOn() does matter. subscribeOn() tells the whole chain which thread to start processing on. You should only call it once per chain. If you call it again lower down the stream it will have no effect. observeOn() causes all operations which happen … Read more
If the closure is not owned by the class you do not have to use [weak self]. In the case of in-line closures the closure is not owned by the class but by the scope it is in and will be released when the scope is left. If the closure is passed in it may … Read more
As Darren put it in the comments: “DoesItLeak can’t be a struct” We cannot have the DoesItLeak be a struct and safely resolve the strong reference cycle issue. Value types like structs exist on the stack frame. Closures and classes are reference types. As the Strong Reference Cycles for Closures section puts it: This strong … Read more
You may use RxExamples for better understanding RxSwift. I found it in RxSwift repo. It helped me in understanding RxSwift. Ok, let’s try to send simple request using Alamofire and RxSwift. First we write request function: func getApi() -> Observable<AnyObject?> { return create{ observer in let request = Alamofire.request(.GET, “http://someapiurl.com”, parameters: nil) .response(completionHandler: { request, … Read more
The main difference between PublishSubject and BehaviorSubject is that the latter one remembers the last emitted item. Because of that BehaviorSubject is really useful when you want to emit states. Why they make project field a BehaviorSubject and not PublishSubject ? Probably because they want to be able to retrieve the last emitted project with … Read more
Have you considered simply creating a new array from the existing value on the relay, appending, then calling accept? myFilter.accept(myFilter.value + [newModel])
This is a very good question. Comparing the two worlds is very hard. Rx is a port of what Reactive Extensions are in other languages like C#, Java or JS. Reactive Cocoa was inspired by Functional Reactive Programming, but in the last months, has been also pointed as inspired by Reactive Extensions as well. The … Read more
