kandi X-RAY | RxRelay Summary
Relays are [RxJava][rx] types which are both an Observable and a Consumer. Basically: A Subject except without the ability to call onComplete or onError. Subjects are useful to bridge the gap between non-Rx APIs. However, they are stateful in a damaging way: when they receive an onComplete or onError they no longer become usable for moving data. This is the observable contract and sometimes it is the desired behavior. Most times it is not. Relays are simply Subjects without the aforementioned property. They allow you to bridge non-Rx APIs into Rx easily, and without the worry of accidentally triggering a terminal state. As more of your code moves to reactive, the need for Subjects and Relays should diminish. In the transitional period, or for quickly adapting a non-Rx API, Relays provide the convenience of Subjects without the worry of the statefulness of terminal event behavior.

QUESTION
I am using the Cocoapod , RxCocoa , RxSwift and Git.
When I run the "git status", some warning will show:
(use "git restore ..." to discard changes in working directory)
modified: Pods/RxCocoa.d
modified: Pods/RxRelay.d
modified: Pods/RxSwift.d
I remember "Pod/*.a Pod/.dia" show too.
How to prevent this in the future?
Must I add something into the .gitignore file??
===================== Edit again:
I viewed the .gitignore a few minutes ago.
My project doesn't ignore the Pods.
My project ignore the files in this way:

QUESTION
I've got a class derived from UIView called ContentListView that goes like this:
ANSWER
Answered 2021-Oct-06 at 04:32After distancing myself from the bug and decided to do another feature story for a few days, I have found the cause of the bug. It was because I used PublishRelays and BehaviorRelays in the UIViewControllers and UIViews. They worked fine anywhere else, just not in UIKit clases. Observables, Signals, Drivers, Completeables, Singles, and Maybes can also work fine in UIViewControllers and UIViews. When I removed all relays in all the crashing UIViewControllers and UIViews and change them to use delegates instead, the crash doesn't appear anymore.
QUESTION
I am studying RxCocoa for UITableView now. Everything works fine with presenting cells but when I add a closure to handle row selection a delay appears. I mean when I tap first row nothing happens, when I tap second row closure shows the reaction I expected for the first row, the third - for the second, etc... Please have a look at my code and help me fix the problem.
...ANSWER
Answered 2020-Nov-25 at 23:13You are using modelDeselected instead of modelSelected.
Also, you should never have a Subject, Relay, or Observable as a var they should always be lets. So var todos = BehaviorRelay... should be let todos = BehaviorRelay...
Lastly:
The usage of subjects [and relays] should largely remain in the realms of samples and testing. Subjects are a great way to get started with Rx. They reduce the learning curve for new developers, however they pose several concerns...

QUESTION
I would like to know the best possible way to handle the following situation, I have tried an approach as it will be described but I have encountered an issue of events calling each other repeatedly in a circular way hence it causes stackoverflow 😂
I have 4 observables as follows: -
...ANSWER
Answered 2020-Sep-09 at 04:56Your helper function updateIndividualObservables(:) triggers an event every time you update which in turn triggers the combineLatest you implemented above.
I would suggest you to keep a State object instead
QUESTION
I need a RxJava subject that ignore onComplete(), So even I used RxRelay, it call onComplete yet :(
ANSWER
Answered 2020-Mar-16 at 12:24It's probably your usage of .zipWith which limits the stream to the shortest participant, regardless of whether the other streams ever finish.
