Looping in UITableViewCell - iphone

Question

I m doing a quiz project where the number of questions and number of options for a questions are dynamic (taken from a service url).Maximum 5 options for a question(but may be decreased).I m displaying it in sectioned UITableView where each question and its options are displayed in one section.I m taking the objects in one section in a NSMutableArray and looping the options each time .But Im getting only the last option.
I couldnot understand why is it so ?
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *hlCellID=#"hlCellID";
UITableViewCell* hlcell=[tableView dequeueReusableCellWithIdentifier:hlCellID];
if(hlcell == nil)
{
hlcell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:hlCellID]autorelease];
hlcell.accessoryType = UITableViewCellAccessoryNone;
hlcell.selectionStyle = UITableViewCellSelectionStyleNone;
lblQuestion = [[UILabel alloc] initWithFrame:CGRectZero];
lblQuestion.tag = 1;
lblQuestion.backgroundColor = [UIColor clearColor];
[lblQuestion setFont:[UIFont fontWithName:#"Helvetica-Bold" size:14]];
[lblQuestion setLineBreakMode:NSLineBreakByWordWrapping];
[hlcell addSubview:lblQuestion];
lblanswers = [[UILabel alloc] initWithFrame:CGRectZero];
lblanswers.tag = 2;
lblanswers.backgroundColor = [UIColor clearColor];
[lblanswers setFont:[UIFont fontWithName:#"Helvetica-Bold" size:12]];
[lblanswers setLineBreakMode:NSLineBreakByWordWrapping];
[hlcell addSubview:lblanswers];
}
int section=indexPath.section;
NSMutableArray *sectionItems=[self.finalarray objectAtIndex:indexPath.section];
int n=[sectionItems count];
hlcell.selectionStyle = UITableViewCellSelectionStyleNone;
NSString *question = [NSString stringWithFormat:#"%#",[[sectionItems objectAtIndex:indexPath.row] objectForKey:#"Question"]];
CGSize constraint1 = CGSizeMake(320, 2000.0f);
CGSize size1 = [question sizeWithFont: [UIFont fontWithName:#"Helvetica-Bold" size:14] constrainedToSize:constraint1 lineBreakMode:NSLineBreakByWordWrapping];
lblQuestion = (UILabel *)[hlcell viewWithTag:1];
lblQuestion.text = [NSString stringWithFormat:#"%#",question];
[lblQuestion setNumberOfLines:0];
lblQuestion.frame = CGRectMake(10,25, size1.width, size1.height);
for(int j=1;j<n;j++)
{
NSLog(#"%#",[[sectionItems objectAtIndex:j] objectForKey:#"Description"]);
NSString *answer = [NSString stringWithFormat:#"%#",[[sectionItems objectAtIndex:j] objectForKey:#"Description"]];
CGSize constraint2 = CGSizeMake(320, 2000.0f);
CGSize size2 = [answer sizeWithFont: [UIFont fontWithName:#"Helvetica-Bold" size:14] constrainedToSize:constraint2 lineBreakMode:NSLineBreakByWordWrapping];
lblanswers = (UILabel *)[hlcell viewWithTag:2];
lblanswers.text = [NSString stringWithFormat:#"%#",answer];
[lblanswers setNumberOfLines:0];
lblanswers.frame = CGRectMake(10,20*j, size2.width, size2.height);
[hlcell.contentView addSubview:lblanswers];
}
return hlcell;
}
I couldn't understand how to set the frame for a lblanswers.
EDIT:

You are doing it wrong. Break down the work in to two parts:
Before that create a dictionary in which each key is question and associated object is an array which contains all the answers.
number of sections = [dictionary count]
number of rows per section = [[dictionary valueForKey:[[dic allKeys] objectAtIndex:indexPath.section]] count]
Questions - create a custom view with UITextView and return that as header for each section and you can adjust the height by calculating and returning height based on question.
Answers - create a custom cell with UITextView and set the text based on section and row.
This strategy will not only simplify the code by given it a structure but also specify the detection of answers selected by user, as you can just store indexPath and check the section for question and row for answer selected by user.
