    <p>Despite many tries I have already done.. I am not getting to display correctly items from an NSArray into a UILabel..</p> <p>When I NSLog the array the console returns me this:</p> <pre><code>2013-01-19 14:34:32.799 bloom[2766:c07] ( "0.877" ) </code></pre> <p>Which is the value I fetched from a website and parsed and etc..</p> <p>The problem is that when I display it in a UILabel it shows me exactly the same thing and I need just the value without quotes to be displayed. Here's is how it is displaying:</p> <p><img src="https://i.stack.imgur.com/G4VdI.png" alt="Displaying problem"> </p> <p>Edit:</p> <p>Here is my code:</p> <pre><code>- (void)configureView { // Update the user interface for the detail item. if (self.detailItem) { for (NSDictionary *valuesDatum in _detailItem) { NSDictionary *itemAtIndex = (NSDictionary *)_detailItem; self.title = [itemAtIndex objectForKey:@"SYMBOL"]; NSString *strUrl = @"http://www.bloomberg.com/quote/"; NSString *ativo = [itemAtIndex objectForKey:@"SYMBOL"]; NSString *consulta = [strUrl stringByAppendingString:ativo]; NSURL *url = [NSURL URLWithString:consulta]; NSData *webData = [NSData dataWithContentsOfURL:url]; NSString *xPathQuery = @"//span[@class=' price'] | //span[@class=' trending_up up'] | //span[@class=' trending_up up']/span | //table[@class='snapshot_table']/tr/td"; TFHpple *parser = [TFHpple hppleWithData:webData isXML:NO]; NSArray *array = [parser searchWithXPathQuery:xPathQuery]; valores = [[NSMutableArray alloc]init]; for (TFHppleElement *element in array) { [valores addObject:[[element firstChild] content]]; } novosValores = [[NSMutableArray alloc]init]; for (NSString *valuesDatum in valores) { NSString *removeNewLine = [[valuesDatum componentsSeparatedByCharactersInSet: [NSCharacterSet newlineCharacterSet]] componentsJoinedByString:@" "]; NSString *removeSpace = [removeNewLine stringByReplacingOccurrencesOfString:@" " withString:@""]; NSString *removeSpaceOne = [removeSpace stringByReplacingOccurrencesOfString:@" " withString:@""]; NSString *trocaVirgulaPonto = [removeSpaceOne stringByReplacingOccurrencesOfString:@"," withString:@"."]; [novosValores addObject:trocaVirgulaPonto]; } valoresFinais = [[NSMutableArray alloc]init]; for (NSString *valuesDatum in novosValores) { NSArray *val = [valuesDatum componentsSeparatedByString:@" - "]; [valoresFinais addObject:val]; } infos = [[NSMutableArray alloc]init]; for (NSArray *dados in valoresFinais) { NSArray *arrayDados = [[NSArray alloc]initWithArray:dados]; for (NSString *teste in arrayDados) { NSArray *arrayTeste = [teste componentsSeparatedByString:@","]; [infos addObject:arrayTeste]; } } NSLog(@"%@",[infos objectAtIndex:0]); NSString *fff = [[NSString alloc] initWithFormat:@"%@", [infos objectAtIndex:0]]; [_detailDescriptionLabel setText:fff]; } } } </code></pre> <p>NEW EDIT:</p> <p>I have this array:</p> <pre><code>2013-01-19 15:43:05.055 bloom[3564:c07] ( "7.730", "0.020", "0.26%", "7.750", "7.650-7.800", "2.333.100", "7.710", "3.730-8.810", "+4.04%" </code></pre> <p>)</p> <p>All I need is a new array with the data from lines 5 and 8 separated by the "-".</p> <p>So anyone has a light??</p> <p>Thanks!!!</p>

Guidance
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.
