Rx 是通过接口表示的计算的通用抽象,它允许你广播和订阅流中的值和其他事件。
Observable<Element>
Observable
RxSwift 是 Reactive Extensions 标准的 Swift 专用实现。
虽然此版本旨在忠于 Rx 的原始精神和命名约定,但该项目还旨在为 Rx API 提供真正的 Swift 优先 API。
可以在 ReactiveX.io 上找到跨平台文档。
与其他 Rx 实现一样,RxSwift 的目的是以对象和一套方法来转换和组合这些异步工作片段,从而轻松地以对象的形式组合异步操作和数据流。
Observable
KVO观察,异步操作,UI事件和其他数据流都在序列抽象下统一。这就是Rx如此简单,优雅和强大的原因。

RxSwift 与它驱动的异步工作一样具有组合性。核心单元是 RxSwift 本身,而其他依赖项可以添加到 UI 工作、测试等。
它由五个独立的组件组成,按以下方式相互依赖:
┌──────────────┐ ┌──────────────┐
│ RxCocoa ├────▶ RxRelay │
└───────┬──────┘ └──────┬───────┘

RxRelay.
PublishRelay,
BehaviorRelayand
ReplayRelay, three simple wrappers around Subjects. It depends on
RxSwift.
RxSwift.
For Xcode 11 and below, use RxSwift 5.x.
RxSwift doesn't contain any external dependencies.
These are currently the supported installation options:
Open Rx.xcworkspace, choose
RxExampleand hit run. This method will build everything and run the sample app
# Podfile
use_frameworks!
target 'YOUR_TARGET_NAME' do
pod 'RxSwift', '6.5.0'
pod 'RxCocoa', '6.5.0'
end
# RxTest and RxBlocking make the most sense in the context of unit/integration tests
target 'YOUR_TESTING_TARGET' do
pod 'RxBlocking', '6.5.0'
pod 'RxTest', '6.5.0'
end
Replace
YOUR_TARGET_NAMEand then, in the
Podfiledirectory, type:
$ pod install
Each release starting with RxSwift 6 includes
*.xcframeworkframework binaries.
Simply drag the needed framework binaries to your Frameworks, Libraries, and Embedded Content section under your target's General tab.
Note: If you're using
RxCocoa, be sure to also drag RxCocoaRuntime.xcframework before importingRxCocoa.
Add this to
Cartfile
github "ReactiveX/RxSwift" "6.5.0"
$ carthage update
Carthage defaults to building RxSwift as a Dynamic Library.
If you wish to build RxSwift as a Static Library using Carthage you may use the script below to manually modify the framework type before building with Carthage:
carthage update RxSwift --platform iOS --no-build
sed -i -e 's/MACH_O_TYPE = mh_dylib/MACH_O_TYPE = staticlib/g' Carthage/Checkouts/RxSwift/Rx.xcodeproj/project.pbxproj
carthage build RxSwift --platform iOS
Note: There is a critical cross-dependency bug affecting many projects including RxSwift in Swift Package Manager. We've filed a bug (SR-12303) in early 2020 but have no answer yet. Your mileage may vary. A partial workaround can be found here.
Create a
Package.swiftfile.
// swift-tools-version:5.0
import PackageDescription
let package = Package(
name: "RxTestProject",
dependencies: [
.package(url: "https://github.com/ReactiveX/RxSwift.git", .exact("6.5.0"))
],
targets: [
.target(name: "RxTestProject", dependencies: ["RxSwift", "RxCocoa"])
]
)
$ swift build
To build or test a module with RxTest dependency, set
TEST=1.
$ TEST=1 swift test
$ git submodule add git@github.com:ReactiveX/RxSwift.git
