Concept

RxCocoa provides extensions to the Cocoa and Cocoa Touch frameworks to take advantage of RxSwift. Texture provides various basic UI components such as ASTableNode, ASControlNode, ASButtonNode and so on. ref: Node Subclasses

So, This Library provides extensions to the Texture frameworks to take advantage of RxSwift like a RxCocoa

ref: Texture + RxSwift Interactive Wrapper

Example

Extension

ASBinder

: Subscribed Observer operates asynchronously.

Expectation Flow Expectation UI

But, Node dosen't know that event value applied on UI before draw.

Unexpectation Flow Unexpectation UI

In this case, Node should use setNeedsLayout. but, [bind:_] doesn't call setNeedsLayout automatically.

Normally, you can use like this code

// Profile NetworkImage Node is default
// username, description is Optional

// *** self is usernameNode supernode
viewModel.username
         .subscribe(onNext: { [weak self] text in 
            self?.usernameNode.rx.text(Node.usernameAttributes).onNext(text)
            self?.setNeedsLayout() // Here
         })
         .disposed(by: disposeBag)

If you use ASBinder then you don't need call setNeedsLayout. ASBinder will operates it automatically.

// Profile NetworkImage Node is default
// username, description is Optional

// *** self is usernameNode supernode
viewModel.username
         .bind(to: usernameNode.rx.text(Node.usernameAttributes),
               setNeedsLayout: self) 
         .disposed(by: disposeBag)

// *** self is descriptionNode supernode
viewModel.desc
         .bind(to: descriptionNode.rx.text(Node.descAttributes),
               setNeedsLayout: self) 
         .disposed(by: disposeBag)

If you don't need setNeedsLayout then just write code like this.

// setNeedsLayout default is nil!
viewModel.username
         .bind(to: usernameNode.rx.text(Node.usernameAttributes)) 
         .disposed(by: disposeBag)

viewModel.desc
         .bind(to: descriptionNode.rx.text(Node.descAttributes)) 
         .disposed(by: disposeBag)
ASBinder Flow Output UI

Installation

RxCocoa-Texture is available through CocoaPods. To install it, simply add the following line to your Podfile:

swift 4.x

pod 'RxCocoa-Texture'

Caution

This library has been migrated to Texture 2.7. When Rx subscribe logic moves from initialization to didLoad method. I no longer faced this problem. When using RxSwift / RxCocoa, it is safe to subscribe from the didLoad method. https://github.com/TextureGroup/Texture/issues/977
