我想从名为“HomeController”的初始ViewController导航到名为“CalendarController”的另一个视图Controller。我想通过使用一个名为“CalendarButton”的按钮来做到这一点。我也想这样做,不参考故事板。由于如何使用按钮从一个ViewController导航到另一个ViewController。 Swift 3(No StoryBoard)
错误说:推导航控制器,不支持
import UIKit
class HomeController: UICollectionViewController,UICollectionViewDelegateFlowLayout {
private let cellId = "cellId"
override func viewDidLoad() {
super.viewDidLoad()
collectionView?.backgroundColor = UIColor.rgb(31, green: 194, blue: 31)
collectionView!.isScrollEnabled = false
collectionView? .register(MenuCell.self, forCellWithReuseIdentifier: cellId)
}
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell{
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: cellId, for:indexPath) as! MenuCell
cell.calendarButton.addTarget(self, action: #selector(calendar), for: .touchUpInside)
return cell
}
func calendar() {
let objVC: CalendarController! = CalendarController()
let aObjNavi = UINavigationController(rootViewController: objVC!)
self.navigationController?.pushViewController(aObjNavi, animated: true)
}
override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) ->Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: view.frame.width, height: view.frame.height)
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
return 0
}
}
//单独的快捷文件
class BaseCell: UICollectionViewCell{
override init(frame: CGRect) {
super.init(frame: frame)
setupViews()
}
func setupViews() {
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
class MenuCell: BaseCell{
lazy var calendarButton: UIButton = {
let button = UIButton(type: .system)
button.setTitle("Calender", for: .normal)
button.setTitleColor(UIColor(red: 0, green: 0, blue: 0, alpha: 1), for: .normal)
button.backgroundColor = .white
button.titleLabel!.font = UIFont.systemFont(ofSize: 20)
button.layer.cornerRadius = 15
return button
}()
func calendar() {
let newViewController = CalendarController()
self.navigationController?.pushViewController(newViewController, animated: true)
}
该应用程序代表不是一个视图控制器 – matt
显示如下代码:class HomeController ... –
