我有onDoubleClick = (e: any): void => {
this.setInputValuesAndSetFocus(e);
}
onBtnPencilClick = (e: any): void => {
this.setInputValuesAndSetFocus(e);
}
private setInputValuesAndSetFocus = (e: any): void => {
this.showButtons = true;
this.readField = false;
this.onFocused = true;
e.focus();
}
内的UITextField
:
UITableViewCell
如何将相同的textField传递给:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! TextFieldTableViewCell
let textField: UITextField = cell.textField
let detail = self.detailItem
textField.text = detail!.valueForKey("name")!.description + detail!.valueForKey("number")!.description
print()
return cell
}
我需要在定义后添加func textFieldDidBeginEditing(textField: UITextField) {
print("executed")
let detail = self.detailItem
let textField: UITextField = self.text.textField
if (textField.text != detail!.valueForKey("name")!.description + detail!.valueForKey("number")!.description) {
detail?.setValue(textField.text, forKey: "name")
}
}
。
我假设它将视图连接到视图控制器,允许它看到textField.delegate = self
函数。

你需要在cellForRowAtIndexPath方法本身中提供UITextFieldDelegate
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! TextFieldTableViewCell
let textField: UITextField = cell.textField
textField.delegate = self
let detail = self.detailItem
textField.text = detail!.valueForKey("name")!.description + detail!.valueForKey("number")!.description
return cell
}
