Execute subscribe method only once at the time in RxSwift

原文 2018-01-16 00:02:44 0 1 ios/ swift/ multithreading/ rx-swift

I have a PublishObject object, which is feed by coming data (approximately 16 times per second). When objects coming so quickly, that can be a situation, when one is still processing, but the new one is ready to use. Is it a way to block executing another processing, when the earlier doesn't end his job?

This is called backpressure, and there are different strategies to handle it.

RxJava has .onBackpressureBuffer() operator, but RxSwift does not support it yet.

Perhaps you can copy Java implementation of it.

RxSwift - subscribe to a method

RxSwift cannot recognize a subscribe method

RxSwift only trigger once

Why RxSwift Subscribe just run once in First launch viewWillAppear?

RxSwift - behavior of subscribe(observer:)

Nesting subscribe calls in RxSwift

RxSwift subscribe block not called

RxSwift: code working only first time

RxSwift subscribe will work when initiated

RxSwift Textfield debounce subscribe is not calling
