Question

我遇到了一个大问题。我有一个textfield我正在做自动完成功能，以显示内部tappe时的项目列表。我在tableView（自动完成tableView）中显示项目。我的UIbutton低于textfield。现在，当我从自动填充文本字段中选择一个项目并单击该按钮时，它没有响应。我不知道为什么。

我已将其放在didendediting和didSelectrow中，但没有用。我已将UIbutton添加到ScrollView（testScroll）

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
           Name.text = selectedCell.textLabel.text;
           [Name resignFirstResponder];
           [testScroll bringSubviewToFront:btnSearch];
           autocompleteTableView.hidden=true;
}
-(void)textFieldDidEndEditing:(UITextField *)textField{
 if(textField==CompanyName)
    {

        [testScroll bringSubviewToFront:btnSearch];

}

}

我哪里出错？

编辑：

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {



    if(textField==Name)
    {

        autocompleteTableView.hidden = NO;

        NSString *substring = [NSString stringWithString:textField.text];
        substring = [substring stringByReplacingCharactersInRange:range withString:string];
        [self searchAutocompleteEntriesWithSubstring:substring];
        return YES;
        if([Name.text length]==0)
        {
            autocompleteTableView.hidden = YES;

        }
    }



}

            autocompleteTableView.backgroundView = nil;

            [viewForautoCompleteTableView addSubview:autocompleteTableView];
            [self.view addSubview:viewForautoCompleteTableView];

            [autocompleteUrls removeAllObjects];
            for(int i=0;i<[arr4 count];i++)
            {
             NSString *curString = [NSString stringWithFormat:@"%@ %@",[[arr4 objectAtIndex:i] valueForKey:@"Name"],[[arr4 objectAtIndex:i]valueForKey:@"LastName"]];

                [autocompleteUrls addObject:curString];

            }




        }
        [autocompleteTableView reloadData];


}

我遇到了同样的问题，并在下面的代码的帮助下修复了。

编辑以下两个功能如下：

in .h:

 int isValueSelected;

in .m：

在viewDidLoad中： isValueSelected = 0;

    - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {

        if (isValueSelected == 1)
        {
            autocompleteTableView.hidden = YES;
            isValueSelected = 0;
        }else{
            NSString *substring = [NSString stringWithString:textField.text];
            substring = [substring stringByReplacingCharactersInRange:range withString:string];
            [self searchAutocompleteEntriesWithSubstring:substring];
            if((substring.length ==0) || ([substring characterAtIndex:0] == 10) || (autocompleteUrls.count == 0)){
                autocompleteTableView.hidden = YES;
            }else{
                autocompleteTableView.hidden = NO;
            }


        }

        return YES;
    }


    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

        UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
        urlField.text = selectedCell.textLabel.text;
        isValueSelected = 1;
        autocompleteTableView.hidden = YES;

    }

UIButton带来了scrollview
