Question

我遇到了问题。我有这个tableview和这个pickerView change the existing image

这是viewcontroller的pickerView函数：

如何修改＆＃34; m＆＃34;在选择了uipicker的单元格中？谢谢大家！

Answer 1

我假设你想让你的M和F出现在你的pickerView中。为此，您必须创建一个引用。这可以通过import UIKit import UIKit.UIGestureRecognizerSubclass class MyRecognizer: UIGestureRecognizer { override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent) { super.touchesBegan(touches, with: event) if touches.count != 1 { state = .failed return } print(self.state.rawValue) self.state = .began } override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent) { super.touchesMoved(touches, with: event) print("moved", self.state.rawValue) } } class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let g = MyRecognizer(target: self, action: #selector(grFired)) self.view.addGestureRecognizer(g) // Do any additional setup after loading the view, typically from a nib. } @objc func grFired(_ g:UIGestureRecognizer) { print("here", g.state.rawValue) } }完成，也可以通过编程方式执行：IBOutlet。另外，我还假设您在视图控制器中仅使用一个let pickerView = UIPickerView()。如果您使用的是多个，请为每个pickerView设置一个标记。这可以在界面构建器中完成，并以编程方式完成：pickerView。然后根据这些标签更改pickerView功能。

Answer 2

创建变量

var currentGender = "M"

将TableViewCell设置为currentGender，如

cell.gender = currentGender

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)
}

Answer 3

创建变量。 var gender =＆＃34; M＆＃34;
再次初始化您的性别变量。在这个委托方法中。 func pickerView（_ pickerView：UIPickerView，didSelectRow row：Int，inComponent component：Int）{ 性别=性别[排] //然后重新加载TableView行 table view.reloadData（） }
将这些行添加到您的cellforrow_atIndexPath。 Cell.genderIdicatorLbl.text =性别注意：genderIndicatorLbl是您的性别指标标签

更新UITableViewCell
