如何将数据从AppDelegate类传递到自定义ViewController？
import UIKit
import LocalAuthentication
class ViewController: UIViewController {
public var config: PasscodeConfig!
func GetAppDelegate(){
print("\(self.config)") /// nil %(
}
override public func viewDidLoad() {
super.viewDidLoad()
self.GetAppDelegate()
}
...
}
不幸的是变量config返回-无
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var appCoordinator: AppCoordinator!
var code = ""
lazy var passcode: Passcode = {
let config = PasscodeConfig(passcodeGetter: {
return self.code
// Return code as string
}, passcodeSetter: { code in
self.code = code
// Save new code
}, biometricsGetter: {
return true
// return Should use biometrics (Touch ID or Face ID) as Bool
})
let passcode = Passcode(window: self.window, config: config)
return passcode
}()
...
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
window = UIWindow(frame: UIScreen.main.bounds)
appCoordinator = AppCoordinator(window: window!)
appCoordinator.start()
self.passcode.authenticateWindow()
return true
}

此外，变量config必须在加载View之前初始化。
我需要做什么？
提前感谢！
您可能希望将设置代码放入AppDelegate方法中，而不是作为惰性变量。
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool
您是否可以发布Passcode和PasscodeConfig类的样子？
