将焦点设置为tableCell中的UITextField

Question

我正在创建一个UITextField动态的表视图.

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];

现在我想在用户触摸单元格时将注意力集中在此文本字段上.我写这个

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

但这不起作用

Answer 1

改变[field resignFirstResponder];与[field becomeFirstResponder];

resignFirstResponder 用于从文本字段中删除键盘(焦点)
