IQKeyboardManager 侧滑 问题

开启iq，侧滑时，会出现tableview 向下移动
解决方法 ：

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        IQKeyboardManager.shared.enable = true
    }
    
    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        IQKeyboardManager.shared.enable = false
    }
