Ios 在“集合”视图中选择单元格以创建新控制器
对编程和以编程方式创建项目非常陌生。我已设置了所有集合视图，但我不知道如何告诉特定单元格导航到新集合视图或详细视图。非常困惑和沮丧。谁能帮我，或者至少给我指出正确的方向。请安静下来，哈哈 这是我的主视图控制器Ios 在“集合”视图中选择单元格以创建新控制器,ios,swift,cell,collectionview,Ios,Swift,Cell,Collectionview,对编程和以编程方式创建项目非常陌生。我已设置了所有集合视图，但我不知道如何告诉特定单元格导航到新集合视图或详细视图。非常困惑和沮丧。谁能帮我，或者至少给我指出正确的方向。请安静下来，哈哈 这是我的主视图控制器 import UIKit class HomeController: UICollectionViewController, UICollectionViewDelegateFlowLayout { var Legends: [Legend] = { var s

主视图控制器的底部代码会打印出一个“选定的”，但它会为每个单元格打印它。。。我假设每个单元格都需要自己的viewController.swift文件？然后告诉该单元格到swift文件以显示内容？？谢谢您的时间。不，您不需要为每个单元格创建自己的
viewController.swiftdidSelectItemAtoverride func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "DetailViewController") as! DetailViewController
controller.selectedIndex = indexPath.row //pass selected cell index to next view.
self.navigationController?.pushViewController(controller, animated: true)
}
controller.selectedIndex=indexath.rowselectedIndexDetailViewControllerDetailViewController.swiftvar selectedIndex = 0
有关更多信息，请参阅演示项目。否您不需要为每个单元格创建自己的
viewController.swiftdidSelectItemAtoverride func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "DetailViewController") as! DetailViewController
controller.selectedIndex = indexPath.row //pass selected cell index to next view.
self.navigationController?.pushViewController(controller, animated: true)
}
controller.selectedIndex=indexath.rowselectedIndexDetailViewControllerDetailViewController.swiftvar selectedIndex = 0
有关更多信息，请参阅演示项目。如果需要，请检查所按下的按钮。您可以检查按下的单元格类型：
if let cell = tableView.cellForRow(at: indexPath) as? VideoCell {
//check some property and go to new UIViewController or UICollectionViewController
//and transfer data
}
如果你想检查什么是卖压。您可以检查按下的单元格类型：
if let cell = tableView.cellForRow(at: indexPath) as? VideoCell {
//check some property and go to new UIViewController or UICollectionViewController
//and transfer data
}
天哪，最后哈哈，非常感谢你。。。它起作用了，我花了一点时间才得到它，但它起作用了。。你太棒了。我从昨天早上7点到午夜一直在做这个。我不能感谢你，所以现在我有所有的工作，纠正我，如果我错了。。。我希望detailViewController是另一个集合视图。。。它的设置基本上与HomeController相似，但具有不同的选项和单元。我是否将detailViewController.swift文件设置为与HomeController.swift/storyboard相同的文件。。。或者这是可能的？不，您不能将其设置为相同的，因为
