iOS应用中的滑出菜单（快速）

Question

I'm trying to build my own slide out menu in swift, but I'm having some troubles. Now, I coded a function that change the view.frame.origin.x so that I got my view to slide on the right. Now, I added a subview at index: 0 and I want to make it show when I slide the main view (content) out.

let navView: NavigationViewController = self.storyboard?.instantiateViewControllerWithIdentifier("navView") as NavigationViewController

    view.insertSubview(navView.view, atIndex: 0)
    addChildViewController(navView)
    navView.didMoveToParentViewController(self)

And that's what happen when I click on the menu logo (at the top-left corner):

    @IBAction func showMenu(sender: AnyObject) {
    println("showMenu")
    if !self.menuIsOpen{
    UIView.animateWithDuration(0.5, delay: 0, usingSpringWithDamping: 1.0, initialSpringVelocity: 0, options: .CurveEaseInOut, animations: { () -> Void in
        self.view.frame.origin.x = 150
        }) { (isHappen: Bool) -> Void in
            if isHappen {
                println("OpenedUp!")
                self.menuIsOpen = true
            }
        }
    } else {
        UIView.animateWithDuration(0.5, delay: 0, usingSpringWithDamping: 1.0, initialSpringVelocity: 0, options: .CurveEaseInOut, animations: { () -> Void in
            self.view.frame.origin.x = 0
            }) { (isHappen: Bool) -> Void in
                if isHappen {
                    println("Closed!")
                    self.menuIsOpen = false
                }
        }
    }
}

So, now, this works but I suppose that the subview slides together with the rest of the main view. How can I make the navigationView not to hide? Or better, to stay there (I mean with the origin.x: 0)

Answer 1

您能否拥有一个与视图控制器（1）关联的导航视图，然后将滑出菜单视图控制器（2）置于该视图控制器（vc1.addSubview（vc2.view））中？然后，您只需保留视图控制器（ 1）的导航栏向上，并且视图控制器（2）将位于其中，因此它不会滑动视图控制器（1）的导航栏。

I know I'm a bit late, but in case anyone else has the same problem: I've implemented a similar mechanic on an app I'm currently working on. To achieve it I used custom interactive transitions, which were introduced in iOS7. I would recommend checking out the following links:

• See Custom Transitions Using View Controllers https://developer.apple.com/videos/wwdc/2013/
• http://www.thinkandbuild.it/ios7-custom-transitions/ In this tutorial, the presented view is rotated to appear on screen; but it's not to much work to adapt the code to silde your menu in from the side and only fill part of the screen.
• http://www.appcoda.com/custom-view-controller-transitions-tutorial/ This gives many examples of the kind of effects you can achieve using custom transitions.

Hope that helps.
