ProtocolOrientedViewModel
===
Create universal view's with different layouts for each platform and share the view logic between them.
Requirements
----
- Swift 3.0+
- iOS 8.0+
- tvOS 9.0+
- macOS 10.10+
Install
----
```
use_frameworks!
pod 'ProtocolOrientedViewModel'
```
Usage
----
This is most useful for universal ios/tvos/mac projects.
Create `Layout`s for your view. For example, portrait and landscape.
Create xib's for each layout of each platform or just create them programmaitaclly.
``` swift
enum HomeScreenLayout: Layout {
case portrait
case landscape
// Define the type of view
typealias ViewType = HomeScreenView
var view: HomeScreenView? {
// return from xib or create and return them here for each layout.
}
}
```
Create your view and its delegate with actions.
``` swift
protocol HomeScreenViewDelegate: class {
func homeScreenViewDidPressSomething(_ homeScreenView: HomeScreenView)
...
}
class HomeScreenView: POView { // POView is a typealias of NSView and UIView for sharing view.
weak var delegate: HomeScreenViewDelegate?
@IBOutlet var someLabel: UILabel?
@IBAction func somethingDidPress() {
delegate?.homeScreenViewDidPressSomething(self)
}
...
}
```
And create your view model
``` swift
class HomeScreenViewModel: ViewModel, HomeScreenViewDelegate {
// MARK: ViewModel
// define the type of view
typealias ViewType = HomeScerenView
var view: HomeScrenView? { didSet{ view?.delegate = self }}
// Make your updates for your view.
typealias LayoutType = ExampleLayout
func render(layout: ExampleLayout?) {
view?.someLabel?.text = dataSource.someValue
view?...
if let layout = layout, case .portrait = layout {
// Do layout specific stuff.
}
}
// MARK: HomeScreenViewDelegate
func homeScreenViewDidPressSomething(_ homeScreenView: HomeScreenView) {
dataSource.someValue = "new value"
render(layout: nil)
}
...
}
```
Call `updateLayoutFor:InView:` function on the view model to update layout of your view.
Also see the example project for universal usage with multiple layouts with xibs in multiple platforms.
