将焦点设置为tableCell中的UITextField [英] Set focus to UITextField in tableCell

问题描述

  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焦点放在此文本字段上。我写这个

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

但这不工作

解决方案

更改 [field resignFirstResponder]; with [field becomeFirstResponder];

resignFirstResponder 用于从文本字段中删除键盘（焦点）

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

解决方案

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

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