    <p>So i got a method to loop through an XML document. The document got a number of answervalues which are being extracted and are printed on the screen in the form of UISegmentedControls. The code i got right now is:</p> <pre><code>- (void) traverseElement:(TBXMLElement *)element { static CGFloat y = 300.0f; static CGFloat dynamicHeight = 400.0f; static int segmentId = 1; do { if([[TBXML elementName:element] isEqualToString:@"wcqAnswerValues"]) { NSString *segmentItemsStr = [TBXML textForElement:element]; NSArray *segmentItemsArray = [segmentItemsStr componentsSeparatedByString:@";"]; answer = [[UISegmentedControl alloc] initWithItems:segmentItemsArray]; answer.frame = CGRectMake(50, y, 400, 40); [answer addTarget:self action:@selector(textpopup:) forControlEvents:UIControlEventValueChanged]; answer.segmentedControlStyle = UISegmentedControlStyleBar; answer.tag = segmentId; [scrollView addSubview:answer]; scrollView.contentSize = CGSizeMake(768, dynamicHeight); [formulierText removeFromSuperview]; [answer release]; y += 40.0f; dynamicHeight += 40.0f; segmentId++; } if ([[TBXML elementName:element] isEqualToString:@"formdata"]) { y = 300.0f; dynamicHeight = 400.0f; segmentId = 1; } // if the element has child elements, process them if (element-&gt;firstChild) [self traverseElement:element-&gt;firstChild]; // Obtain next sibling element } while ((element = element-&gt;nextSibling)); } -(void)textpopup:(UISegmentedControl *)sender { if (sender.tag == 1) { // if the tag of the sender is 1, then do something. } } </code></pre> <p>What i want to achieve is this:</p> <p>Each UISegmentedControl that is being printed on the screen has to have a unique number or id so i can separately assign actions to them. What is the best way to achieve this?</p> <p><strong>EDIT:</strong> Fixed it. I will update my code.</p>

    1. COThe code that you have posted is invalid. There is no 'do' for your 'do-while' statement. Double check against what you have in your project.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
