ios - 更新 UITableViewCell

Question

我遇到了问题。我有这个 tableview 和这个 pickerView

这是 View Controller 的 pickerView 函数:

let gender = ["M","F"]

@IBOutlet weak var dataTableView: UITableView!

//pickerFuncs

func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return 1
}

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    return gender[row]
}

func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return gender.count
}

func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    print(gender[row])
}

如何通过uipicker的选择来修改单元格中的“m”？谢谢大家!

Answer 1

创建变量

var currentGender = "M"

使用currentGender设置您的TableViewCell，例如

cell.gender = currentGender

当您在UIPickerView中选择一行时，

func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    currentGender = gender[row]
    // Then reload your TableView row
    let indexPath = IndexPath(item: rowNumber, section: 0)
    tableView.reloadRows(at: [indexPath], with: .top)
}
