获取界面UIViewController

1. 获取界面view controller

extension UIView {
    //返回该view所在VC
    func firstViewController() -> UIViewController? {
        for view in sequence(first: self.superview, next: { $0?.superview }) {
            if let responder = view?.next {
                if responder.isKind(of: UIViewController.self){
                    return responder as? UIViewController
                }
            }
        }
        return nil
    }
}

然后可以调用里面的函数啦, 赞

                return tableView
            }
