Ios 如何从侧菜单中显示和取消活动

我从中实现了侧菜单框架

我想在我自己的类中实现SideMenu类中的方法，以便在显示或取消侧菜单时可以更改UIImage

这是来自侧菜单类的方法

// MARK: UIViewControllerTransitioningDelegate protocol methods

// return the animator when presenting a viewcontroller
// rememeber that an animator (or animation controller) is any object that aheres to the UIViewControllerAnimatedTransitioning protocol
open func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    self.presenting = true
    SideMenuTransition.presentDirection = presented == SideMenuManager.menuLeftNavigationController ? .left : .right
    return self
}

// return the animator used when dismissing from a viewcontroller
open func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    presenting = false
    return self
}

您需要子类化UISideMenuNavigationController以获得ViewDidDisplay和ViewDidEnglishe。检查这个答案
