Usage
Step 1: Configure the Injector
Start by configuring the Blindside injector in your application delegate:
import Blindside
class AppDelegate: UIResponder, UIApplicationDelegate {
var injector: BSInjector?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
self.injector = BSInjector.new(application: self)
// Add your module bindings here
return true
}
}
Step 2: Define Modules
Next, define your modules to provide bindings for your dependencies:
import Blindside
class AppModule: NSObject, BSModule {
func bindings(bind: BSBinder) {
bind.bind(MyServiceProtocol.self, toBlock: { injector in
return MyServiceImpl()
})
}
}
Step 3: Resolve Dependencies
To resolve dependencies in your code, you can inject them by property or constructor injection:
import Blindside
class MyViewController: UIViewController {
var myService: MyServiceProtocol? {
didSet {
// Do something with the injected service
}
}
override func viewDidLoad() {
super.viewDidLoad()
self.injector?.injectProperties(self)
// Your code...
}
}
import Blindside
class MyViewController: UIViewController {
let myService: MyServiceProtocol
required init(injector: BSInjector) {
self.myService = try! injector.getInstance(MyServiceProtocol.self)
super.init(nibName: nil, bundle: nil)
}
}
