导航抽屉中的UIViewController之间的过渡

Question

I am Using Swift 3. I have searched about this and found the solution

navigationDrawerController?.TransitionFromRootViewController

but when I used this line it say TransitionFromRootViewController is not a function.

So I tried Using

navigationDrawerController?.transition(from: RootViewController(), to: destViewController(), duration: 0.2, options: .transitionCrossDissolve, animations: nil, completion: nil)

but it shows error that the:

"child view controller must have a common parent view controller when calling transitionfrom view controller"

Can anyone help me please? If someone can push an example of navigation drawer with the switching would be a great.

Answer 1

Here is the solution, which I posted to the NavigationDrawerController example project in the programmatic directory, Material 2.1.2 .

It shows how to transition with multiple navigation controllers, and by itself.

import UIKit
import Material

class LeftViewController: UIViewController {
private var transitionButton: FlatButton!

open override func viewDidLoad() {
    super.viewDidLoad()
    view.backgroundColor = Color.blue.base

    prepareTransitionButton()
}

@objc
internal func handleTransitionButton() {
    // Transition the entire NavigationDrawer rootViewController.
    // navigationDrawerController?.transition(to: TransitionedViewController(), completion: closeNavigationDrawer)

    // Transition the ToolbarController rootViewController that is in the 
    // NavigationDrawer rootViewController.
    (navigationDrawerController?.rootViewController as? ToolbarController)?.transition(to: TransitionedViewController(), completion: closeNavigationDrawer)
}

internal func closeNavigationDrawer(result: Bool) {
    navigationDrawerController?.closeLeftView()
}

private func prepareTransitionButton() {
    transitionButton = FlatButton(title: "Transition VC", titleColor: Color.white)
    transitionButton.addTarget(self, action: #selector(handleTransitionButton), for: .touchUpInside)

    view.layout(transitionButton).horizontally().center()
}
}
