ios - 来自抽屉导航的 UIViewController 之间的转换

Question

我正在使用 Swift 3。我已经搜索过这个并找到了解决方案

navigationDrawerController?.TransitionFromRootViewController

但是当我使用这一行时，它说 TransitionFromRootViewController 不是一个函数。

所以我尝试使用

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

但它显示错误:

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

谁能帮帮我？如果有人可以推送带有切换功能的抽屉导航的示例，那就太好了。

Answer 1

这是解决方案，我将其发布到 NavigationDrawerController example project在程序目录中， Material 2.1.2 .

它展示了如何使用多个导航 Controller 进行转换以及如何单独进行转换。

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()
}
}
