Vin*_*los 1 ios firebase swift firebase-authentication
我正在做一个外部功能来检查用户是否已经登录到Firebase。
我的代码正在运行,但是在尝试确保最终关闭当前的VC时,出现错误。
我的问题是:如何获得当前的VC或如何使用self。引用该函数被调用的当前VC?
class Helper{
static func checkIfLogged() {
Auth.auth().addStateDidChangeListener { auth, user in
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "HomeViewController")
UIApplication.shared.keyWindow?.rootViewController = controller
self.dismiss(animated: true, completion: nil) **** ERROR IS HERE ***
}
}
}

extension UIApplication{
class func getPresentedViewController() -> UIViewController? {
var presentViewController = UIApplication.shared.keyWindow?.rootViewController
while let pVC = presentViewController?.presentedViewController
{
presentViewController = pVC
}
return presentViewController
}
}

只需添加此扩展名并调用:UIApplication。getPresentedViewController()
