如何在UITableView中成为FirstResponder UITextField

Question

stackOverflow上有很多相同的问题。 但我无法解决这个问题。

如何在UITableView中成为FirstResponder UITextField？ 我想像下面这样做。 按下编辑按钮，然后将焦点放在UITableView中的UITextField上。

-(void)setEditing:(BOOL)editing animated:(BOOL)animated{
    if (editing) {
        for ( int i = 0 ; i < items.count  ; ++ i ) {
            UITextField * ii = [textFields_ objectAtIndex:i];
            if ([textFields_ objectAtIndex:i] == [NSNull null]) {
            }
            [ii setUserInteractionEnabled:YES];
            if (ii.tag == 0) {
            [ii becomeFirstResponder];
        }
    }
}

-(void)setEditing:(BOOL)editing animated:(BOOL)animated{
    [super setEditing:editing animated:YES];
    if (editing) {
        for ( int i = 0 ; i < items.count  ; ++ i ) {
            UITextField * ii = [textFields_ objectAtIndex:i];
            [ii setUserInteractionEnabled:YES];
            if (ii.tag == 0) {
                [ii becomeFirstResponder];
            }
        }
    }
}
