Question

我有这个代码 NSString * localStringValue;

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    localStringValue = [m_textfield cellForRowAtIndexPath:indexPath].textLabel.text; 
    localStringValue = [m_textfield cellForRowAtIndexPath:indexPath].detailTextLabel.text; 
    NSArray* toReload = [NSArray arrayWithObjects: indexPath, self.selectedIndexPath, nil];
    self.selectedIndexPath = indexPath;
    if ([[tableView cellForRowAtIndexPath:indexPath] accessoryType] == UITableViewCellAccessoryCheckmark){
        UploadView *uploadview = (UploadView *)self.view;
        if (uploadview != nil)
        {
            [m_owner uploadString:localStringValue];
            //[self dismissModalViewControllerAnimated:YES];
        }

        [[m_textfield cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryNone];
    }

    else {

        [[tableView cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryCheckmark];

    }
}

在这段代码中我正在将localStringValue同步到google-doc，当我点击单元格时，如果复选标记在那里.localStringValue包含tableview单元格中的值。此时所有事情都正常工作。但我需要的是我想要将此值传递给按钮单击，这意味着如果用户选择多行，我想要localStringValue中的所有值并通过此代码传递它

- (IBAction)doUpload:(id)sender
{
            UploadView *uploadview = (UploadView *)self.view;
            if (uploadview != nil)
            {
                [m_owner uploadString:@""];
                //[self dismissModalViewControllerAnimated:YES];
            }

}

我想在[m_owner uploadString:localstringvalue];中传递localstringvalue 这该怎么做？提前谢谢。

Answer 1

您可以创建NSMutableArray作为类变量，并且可以将字符串添加到didSelectRowAtIndexPath上的字符串。稍后点击按钮，您可以处理NSMutableArray逐个获取字符串并将其发送到google-doc ...等。

您需要更新

- (void)doUpload:(NSString*)stringValue
{
            UploadView *uploadview = (UploadView *)self.view;
            if (uploadview != nil)
            {
                [m_owner uploadString:localstringvalue];
                //[self dismissModalViewControllerAnimated:YES];
            }
}

还有一件事 localStringValue = [m_textfield cellForRowAtIndexPath:indexPath].textLabel.text //再次分配字符串，这条线没有任何意义。

将DidSelectRowAtIndexPath中的字符串传递给按钮单击操作
