这让我很难过,我尝试了一些教程和堆栈答案的方法,但它仍然没有构建。桌面视图用segue单独查看
所以基本上:
- 即时得到的核心数据,然后放置该成一个数组。 (正常工作)
- 之后,我只是在细胞中显示的姓氏和名字(正常工作)对细胞
- 用户点击看athleteDetalView
我已经把一些打印语句,看看它的出错了。
非常感谢您的意见。
import UIKit
import CoreData
class athleteViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
//labels
@IBOutlet weak var athleteLabel: UILabel!
//buttons
@IBOutlet weak var athleteCreate: UIBarButtonItem!
@IBOutlet weak var athleteTableView: UITableView!
var athleteArray:[Athlete] = []
var myIndex = 0
override func viewDidLoad() {
super.viewDidLoad()
athleteTableView.delegate = self
athleteTableView.dataSource = self
self.fetchData()
self.athleteTableView.reloadData()
}

return 1

你的实际问题是什么?你说这段代码没有编译,但是你说你把打印语句用于调试,那么你会得到一个编译错误还是运行时错误? –
主要使用打印语句来查看数据是否实际上被加载到它所在的变量中。但是它不会将它们发送到其他视图。我试过了: let currentCell = tableView.cellForRow(at:indexPath)!作为UITableViewCell 然后我想传递的变量以及这里讨论的内容 [链接](https://stackoverflow.com/questions/28430663/send-data-from-tableview-to-detailview-swift) –
