如何在单个tableview中传递多个数据

Question

您好，我有两个不同的数组数据需要传递给视图控制器，我的 ViewControllers 设计是相同的，但唯一的区别是数据。我怎样才能做到这一点？这是我的代码

var attendance: [GAttendance]!
var subjectAttendances: [GAttendances]!

// In my A controller
let detailAbsenceVC                 = DetailAbsenceVC()
detailAbsenceVC.attendance      = attendances
self.present(detailAbsenceVC, animated: true)

// In my B controller
let detailVC                    = DetailAbsenceVC()
detailVC.subjectAttendances = subjectAttendances
self.present(detailVC, animated: true, completion: nil)

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    tableView.deselectRow(at: indexPath, animated: true)
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return attendance.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: GStudentAbsenceCell.cellID, for: indexPath) as! GStudentAbsenceCell
    let attendanceItem = attendance[indexPath.row]
    cell.configureCell(attendance: attendanceItem)
    return cell
}

Answer 1

如果你不区分你来自A还是B，你只需要一个数组来存储DetailAbsenceVC中的数据，我们称之为detailData：

class DetailAbsenceVC : UIViewController {
    var detailData = [GAttendance]()

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return detailData.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: GStudentAbsenceCell.cellID, for: indexPath) as! GStudentAbsenceCell
        let attendanceItem = detailData[indexPath.row]
        cell.configureCell(attendance: attendanceItem)
        return cell
    }
}

然后，在 A/B 控制器中，只需设置 detailData:

// In my A controller
let detailAbsenceVC         = DetailAbsenceVC()
detailAbsenceVC.detailData  = attendances
self.present(detailAbsenceVC, animated: true)

// In my B controller
let detailVC        = DetailAbsenceVC()
detailVC.detailData = subjectAttendances
self.present(detailVC, animated: true, completion: nil)
