README
What is Hanson?
Hanson is a simple, lightweight library to observe and bind values in Swift. It's been developed to support the MVVM architecture in our Blendle iOS app. Hanson provides several advantages to using KVO in Swift, such as a Swiftier syntax, no boilerplate code, and the ability to use it in pure Swift types.
Example Usage
The most basic use case is to simply observe an Observable
for changes:
let observable = Observable("Hello World")
observe(observable) { event in
// Invoked whenever observable.value is set.
print("Value changed from \(event.oldValue) to \(event.newValue)")
}
Hanson also provides a wrapper around KVO, so you can do the following to observe a UITextField
's text
property for changes:
let textField = UITextField()
let textFieldObservable = textField.dynamicObservable(keyPath: #keyPath(UITextField.text), type: String.self)
observe(textFieldObservable) { event in
print("Text field value changed from \(event.oldValue) to \(event.newValue)")
}
Furthermore, you can also use Hanson to bind an observable to another observable. Let's say we have a view model that's responsible for loading data, and we want the view to show an activity indicator while the view model is loading data:
class ViewModel {
let isLoadingData = Observable(false)
}
class View {
let showsActivityIndicator = Observable(false)
}
let viewModel = ViewModel()
let view = View()
bind(viewModel.isLoadingData, to: view.showsActivityIndicator)
Now, whenever the view model's isLoadingData
property is set to a different value, it will automatically be set to the view's showsActivityIndicator
property.
Binding is also supported from and to KVO-backed observables. To bind a text field's content to a label:
let textField = UITextField()
let textFieldObservable = textField.dynamicObservable(keyPath: #keyPath(UITextField.text), type: String.self)
let label = UILabel()
let labelObservable = label.dynamicObservable(keyPath: #keyPath(UILabel.text), type: String.self)
bind(textFieldObservable, to: labelObservable)
If you want to handle the binding yourself, you can also provide a closure that will be invoked when a new value should be set. In the following example, we'll bind an isLoadingData
observable to a UIActivityIndicatorView
:
let isLoadingData = Observable(false)
let activityIndicatorView = UIActivityIndicatorView()
bind(isLoadingData, to: activityIndicatorView) { activityIndicatorView, isLoadingData in
if isLoadingData {
activityIndicatorView.startAnimating()
} else {
activityIndicatorView.stopAnimating()
}
}
Hanson also supports observering notifications sent through a NotificationCenter
. For example, to observe when an application is entering the background:
let observable = NotificationCenter.default.observable(for: Notification.Name.UIApplicationDidEnterBackground)
observe(observable) { notification in
print("Application did enter background")
}
Requirements
- iOS 8.0+ / macOS 10.9+ / tvOS 9.0+
- Xcode 8
Installation
Hanson is available through either CocoaPods or Carthage.
Cocoapods
- Add
pod 'Hanson'
to yourPodfile
. - Run
pod install
.
Carthage
- Add
github 'blendle/Hanson'
to yourCartfile
. - Run
carthage update
. - Link the framework with your target as described in Carthage Readme.
Swift Package Manager
- In Xcode, select your project and scroll to
Frameworks, Libraries, and Embedded Content
. - Click the
+
. - At the bottom of the frameworks and libraries window that opens, select
Add other...
and thenAdd package dependency...
. - Paste
https://github.com/blendle/Hanson.git
in the search textfield and follow through with the assistant.
Building
The project obviously builds fine through Xcode, just load up Hanson.xcodeproj
and run it.
For convenience, we've included a few scripts and a Makefile
that allow you to build Hanson from the command line and through continuous integration. They are inspired by GitHub's Scripts to Rule Them All boilerplate:
|-- script/
|-- etc/
|-- config.sh # Contains basic configuration parameters
|-- bootstrap # Prepares the project
|-- setup # Sets up the local building process
|-- test # Runs tests locally
|-- cisetup # Sets up the CI building process
|-- citest # Runs tests in a CI environment
To get started:
$ make
To skip setup and immediately start testing:
$ make test
Make sure all tests pass before opening a Pull Request.
