Set focus to UITextField in tableCell

问题

I am creating a table view with UITextFields dynamically.

l_textField = [[UITextField alloc] initWithFrame:TextFieldFrame];
l_textField.tag = cellRow;

l_textField.delegate = self;
l_textField.font = [UIFont boldSystemFontOfSize:14];
l_textField.textColor = [UIColor blackColor];
[l_textField setEnabled:YES];

[cell.contentView addSubview:l_textField];

And now I want to set focus on this text field when user touch cell. I write this

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)newIndexPath {
    UITextField* field = (UITextField *) [tblView viewWithTag: newIndexPath.row];
    [field resignFirstResponder];
}

But this doesn't work

回答1:

change [field resignFirstResponder]; with [field becomeFirstResponder];

resignFirstResponder is used to remove keyboard (focus) from text field

回答2:

I've faced the same issue here, even using correctly the [field becomeFirstResponder];.

I also used tags to get the objects I have inside the cell. Your didSelectRowAtIndexPath should look like this to get the right cell:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    currentRow = indexPath.row;

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    UITextField *indexField = (UITextField *)[cell viewWithTag:101];
    [indexField becomeFirstResponder];
}

It worked like a charm for me.

Swift 3

myTextField.becomeFirstResponder()

My Code. Take index path of current cell. And get cell of next indexpath.row. And called ** cell1.txtFindings.becomeFirstResponder() **

  if  let textFieldIndexPath = specsListView.indexPath(for: cell){
        let newIndexPath = IndexPath(row: textFieldIndexPath.row + 1, section: 0)

        if let cell1: SpecsTableViewCell = specsListView.cellForRow(at: newIndexPath) as? SpecsTableViewCell{
            cell1.txtFindings.becomeFirstResponder()
        }
}
