我只想在代码中实现这种转换。

但我似乎没有使用 Material 的 navigationBarViewController 中的 navigationController。
那么pushViewController方法不能用于页面转换吗？
此代码是使用材料
import UIKit
import Material
/// MaterialCollectionViewDelegate methods.
extension FeedViewController: MaterialCollectionViewDelegate {
/// Executed when an item is selected.
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
print(indexPath)
// --------------------------------My Question--------------------------------------//
let vc = DetailViewController()
self.navigationBarViewController?.pushViewController(vc, animated: true)
// ----------------------------------------------------------------------//
}
}
class FeedViewController: UIViewController {
private var collectionView: MaterialCollectionView = MaterialCollectionView()
override func viewDidLoad() {
super.viewDidLoad()
prepareView()
prepareCollectionView()
}
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
collectionView.frame = view.bounds
collectionView.reloadData()
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
navigationBarViewController?.navigationBarView.titleLabel?.text = "Home"
}
/// Prepares view.
private func prepareView() {
view.backgroundColor = MaterialColor.grey.lighten4
}
/// Prepares the collectionView
private func prepareCollectionView() {
collectionView.dataSource = self
collectionView.delegate = self
collectionView.spacingPreset = .Spacing1
collectionView.contentInsetPreset = .Square1
collectionView.registerClass(MaterialCollectionViewCell.self, forCellWithReuseIdentifier: "MaterialCollectionViewCell")
// To avoid being hidden under the hovering MenuView.
view.addSubview(collectionView)
}
