Question

I’m parsing an xml file from an url and it displays the content correctly.here is my xml file

<gold>
<price>
<title>22 K Gold - SGD $69.50</title>
</price>
<price>
<title>24 K Gold - SGD $62.50</title>
</price>
</gold>

now its displays each content in cell like the image below

Now i need to display 22kgold in a cell and SGD $69.50 in a cell.and also the next element same.And also to print these values in two labels.

here is my code in .m file

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSMutableArray *tableArray = [[NSMutableArray alloc]init];

    NSData *xmlData = [[NSData alloc]initWithContentsOfURL:[NSURL URLWithString:@"http://www.p41tech.com/img/application/android/server/kamala/goldprice.xml"]];
    tbxml = [[TBXML alloc]initWithXMLData:xmlData];


    TBXMLElement * root = tbxml.rootXMLElement;

    if (root)
    {
        TBXMLElement * elem_PLANT = [TBXML childElementNamed:@"price" parentElement:root];

        while (elem_PLANT !=nil)
        {
            TBXMLElement * elem_BOTANICAL = [TBXML childElementNamed:@"title" parentElement:elem_PLANT];
            NSString *botanicalName = [TBXML textForElement:elem_BOTANICAL];
            [tableArray addObject:botanicalName];
            elem_PLANT = [TBXML nextSiblingNamed:@"price" searchFromElement:elem_PLANT];
        }      
    }

    label1.text=@"%@",botanicalName;
    label2.text=@"%@",elem_PLANT;
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [tableArray count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    cell.backgroundView = [ [[UIImageView alloc] initWithImage:[ [UIImage imageNamed:@"download.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:5.0] ]autorelease];   
    cell.textLabel.backgroundColor=[UIColor clearColor];
    cell.textLabel.text = [tableArray objectAtIndex:indexPath.row];
    cell.selectionStyle = UITableViewCellSelectionStyleNone;


    tableView.backgroundColor=[UIColor clearColor];
    return cell;
}

My label contents are not displayed and i need to separate string in each cell by ‘-‘.Please guide me..

Thanks in advance

You probably meant:

label1.text = [NSString stringWithFormat:@"%@", botanicalName];
label2.text = [NSString stringWithFormat:@"%@", elem_PLANT];

otherwise you were assigning the string “%@” into the labels, and ignoring botanicalName and elem_PLANT.

To separate the rows into two parts, you can use the following inside your tableView:cellForRowAtIndexPath: method:

NSArray *parts = [[tableArray objectAtIndex:indexPath.row] componentsSeparatedByString:@" - "];
NSString *item = [parts objectAtIndex:0];
NSString *price = [parts objectAtIndex:1];

You can then either:

1. Use one of the UITableViewCellStyleSubtitle, UITableViewCellStyleValue1, or UITableViewCellStyleValue1 cell styles, and assign the item and price variables to the cell.textLabel.text and cell.detailTextLabel.text properties, or

2. you could add a custom cell view, and assign them to your own labels within that view.
