Usage

EasyNavigatable, NavButtonConfigurable

import BaseVCKit


public class ViewController: UIViewController, EasyNavigatable {

    private lazy var nextBtn: UIView = {
        let v = UIButton()
        v.setTitle("Next", for: .normal)
        v.addTarget(self, action: #selector(next), for: .touchUpInside)
        self.view.addSubview(v)
        return v
        }()

    public override func viewDidLoad() {
        super.viewDidLoad()

        nextBtn.snp.makeConstraints { (make) in
            make.left.right.bottom.equalToSuperview()
            make.height.equalTo(60)
        }
    }

    public override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        startKeyboardAnimationObserve()
    }

    public override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)

        stopKeyboardAnimationObserve()
    }


    // MARK: - Action

    func next(sender: UIButton!) {
        let nextVC = UIViewController()
        push(nextVC, isHideBottomBar: true)
    }
}


// NavButtonConfigurable
extension ViewController: NavButtonConfigurable {

    public var backButtonIcon: UIImage? {
        return UIImage(named: "back")
    }
    public var backButtonTitle: String? {
        return ""
    }
    public var closeButtonIcon: UIImage? {
        return UIImage(named: "close")
    }
}

        }
    }


    // MARK: - Actions

    @objc private func done(sender:UIButton!) {
        view.endEditing(true)
    }
}

// KeyboardObserable
extension ModalViewController: KeyboardSanpable {

    public var keyboardFollowView: UIView? {

        startKeyboardAnimationObserveWithViewWillAppear()
    }

    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)

        stopKeyboardAnimationObserveWithViewWillDisAppear()
    }
}

TabbarVCGenerator

import UIKit
import BaseVCKit

class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
