Usage

- just like

    self.MBackButton(image: "Your custom back image")
}

- or

override func viewWillAppear(_ animated: Bool)

    self.MBackButton(image: "Your custom back image", popMethod: ENUMPopMethod.Root, title: "Back")

PS

自定义返回按钮后，屏幕左边缘滑动返回会失效，解决办法如下：

1、让 ViewController 继承 UIGestureRecognizerDelegate

2、

override func viewDidLoad()
{
    super.viewDidLoad()
    self.navigationController?.interactivePopGestureRecognizer?.delegate = self        
}

3、

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool
{
        if gestureRecognizer == self.navigationController?.interactivePopGestureRecognizer
        {
            return self.navigationController!.viewControllers.count > 1
        }
        return true      
}
