If you want to get all events of an application, you can get events from UIApplication.sendEvent(_:). But, following implementations are needed to get events from it.
/* MyApplication.swift */
class MyApplication: UIApplication {
override sendEvent(_ event: UIEvent) {
super.sendEvent(event)
print(event)
}
}/* main.swift */
private let applicationClassName: String = {
#if DEBUG
return NSStringFromClass(MyApplication.self)
#else
return NSStringFromClass(UIApplication.self)
#endif
}()
UIApplicationMain(
CommandLine.argc,
UnsafeMutableRawPointer(CommandLine.unsafeArgv)
.bindMemory(
to: UnsafeMutablePointer<Int8>.self,
capacity: Int(CommandLine.argc)),
applicationClassName,
NSStringFromClass(AppDelegate.self)
)/* AppDelegate.swift */
// @UIApplicationMain <- comment out
class AppDelegate: UIResponder, UIApplicationDelegate {
...
}Degu makes them easy!!
Usage
1. ApplicationProxy
This is an example. There are only 2 implementations what you have to.
- set a delegate to
ApplicationProxy.shared.delegate - implement
ApplicationProxyDelegate
import Degu
class AppDelegate: UIResponder, ApplicationDelegate {
...
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
#if DEBUG
ApplicationProxy.shared.delegate = self
#endif
...
return true
}
...
}
extension AppDelegate: ApplicationProxyDelegate {
func applicationProxy(_ proxy: ApplicationProxy, didSendEvent event: UIEvent) {
print(event)
}
}In addition, you can get lifecycle method call of all ViewControllers.
func applicationProxy(_ proxy: ApplicationProxy, didCallLifeCycle lifeCycle: ViewControllerLifeCycle, ofViewController viewController: UIViewController) {
print("ViewController = \(viewController)")
print("LifeCycle = \(lifeCycle)")
}2. Override load or initialize method
+(void)load and +(void)initialize are not permitted by Swift.
You can override +(void)load and +(void)initialize in Extension of RuntimeHandler.
extension RuntimeHandler {
open override class func handleLoad() {
// do something
}
open override class func handleInitialize() {
// do something
}
}handleLoad and handleInitialize are not called Subclass of RuntimeHandler. It only works in Extension of RuntimeHandler.
