我正在使用Swift 3.我已经搜索了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:
"从视图控制器调用transition时,子视图控制器必须具有公共父视图控制器"
有人能帮帮我吗?如果有人可以通过切换来推动导航抽屉的例子,那就太棒了。
答案 0 :(得分:1)
以下是解决方案,我将其发布到程序化目录中的NavigationDrawerController example project,材料2.1.2。
它展示了如何使用多个导航控制器进行转换,以及它自身。
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()
}
}
