Welcome to the documentation for RXLifecycle. This guide provides detailed information on how to use RXLifecycle in your iOS projects. RXLifecycle is a powerful library that helps you manage the lifecycle of your RxSwift observables and dispose them appropriately, ensuring efficient resource usage.
Installation
To integrate RXLifecycle into your project, you can use both Cocoapods and Swift Package Manager. Follow the steps provided below based on your preferred package manager:
Cocoapods:
To integrate RXLifecycle using Cocoapods, add the following line to your Podfile:
pod 'RXLifecycle'
Swift Package Manager:
To integrate RXLifecycle using Swift Package Manager, add the following dependency to your `Package.swift` file:
dependencies: [
.package(url: "https://github.com/RXLifecycle.git", from: "1.0.0")
]
Usage
After integrating RXLifecycle into your project, you can start using it to manage the lifecycle of your RxSwift observables.
1. Importing
To use RXLifecycle, import the module in your source file:
import RXLifecycle
2. Observables
RXLifecycle provides lifecycle-aware observables that automatically dispose themselves when the specified lifecycle event occurs. You can use the following observables:
- rx.lifecycleWillAppear: An observable that emits an event when the view controller’s `viewWillAppear` method is called.
- rx.lifecycleDidAppear: An observable that emits an event when the view controller’s `viewDidAppear` method is called.
- rx.lifecycleWillDisappear: An observable that emits an event when the view controller’s `viewWillDisappear` method is called.
- rx.lifecycleDidDisappear: An observable that emits an event when the view controller’s `viewDidDisappear` method is called.
- rx.lifecycleDeinit: An observable that emits an event when the view controller is being deallocated.
3. Subscribing
Once you have the desired observable, you can subscribe to it and handle events accordingly. Here’s an example:
// Assuming `disposeBag` is your RxSwift DisposeBag instance
// and `myObservable` is an instance of one of the RXLifecycle observables
myObservable
.subscribe(onNext: { event in
// Handle the event here
})
.disposed(by: disposeBag)
Examples
Here are a few examples demonstrating how to use RXLifecycle in different scenarios:
Example 1: Disposing an observable when the view disappears
To dispose an observable when the view disappears, you can use the `rx.lifecycleDidDisappear` observable as follows:
rx.lifecycleDidDisappear
.subscribe(onNext: { _ in
// Dispose the observable here
})
.disposed(by: disposeBag)
Example 2: Performing an action when the view controller is deallocated
If you want to perform an action when the view controller is being deallocated, you can use the `rx.lifecycleDeinit` observable:
rx.lifecycleDeinit
.subscribe(onNext: { _ in
// Perform the action here
})
.disposed(by: disposeBag)
Conclusion
Congratulations! You now have a good understanding of how to use RXLifecycle in your projects. Utilize the provided RXLifecycle observables to efficiently manage your RxSwift observables’ lifecycles and improve resource usage. Enjoy using RXLifecycle and if you have any further questions, don’t hesitate to ask for help.
