在这里,我向firstVC tableview发送secondVC文本字段值,但在tableview中没有收到委托值。
这是我的代码:
在firstVC中:
import UIKit
class CreateBusinessViewController: UIViewController, MyDataSendingDelegateProtocol, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var tableView: UITableView!
var iteamsArray = [String]()
override func viewDidLoad() {
super.viewDidLoad()
}
func sendDataToFirstViewController(myData: String) {
self.iteamsArray.append(myData)
print(iteamsArray)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if (segue.identifier == "addSegue") {
let vc = segue.destination as! CreatePopUpViewController
vc.delegate = self
}
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return iteamsArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! BusinessTableViewCell
cell.nameLabel.text = iteamsArray[indexPath.row]
return cell
}
}
在secondVC中:
protocol MyDataSendingDelegateProtocol {
func sendDataToFirstViewController(myData: String)
}
class CreatePopUpViewController: UIViewController {
var delegate: MyDataSendingDelegateProtocol?
@IBOutlet weak var addTf: UITextField!
@IBAction func saveButn(_ sender: Any) {
self.delegate?.sendDataToFirstViewController(myData: addTf.text!)
dismiss(animated: true, completion: nil)
}
}
如何将secondVC文本字段数据添加到firstVC数组?
