How to parse a json file with /n and br line breaks in iPhone? - objective-c

Question

I am currently parsing a json file from a web server which was generated using a php son generator.But now the json file has /n and br tags in the content and when i parse the file,the app displays the /n and br tags.
Heres my code:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath{
static NSString *cellIdentifier=#"identity";
CustomCell2 *cell=[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
cell.loader.hidden = NO;
[loader startAnimating];
[[NSBundle mainBundle]loadNibNamed:#"CustomCell11" owner:self options:nil];
cell=(CustomCell2 *)tblCell;
NSMutableArray *dictionaryObject=[_newsArray objectAtIndex:indexPath.row];
lblMain.text=[dictionaryObject valueForKey:#"MainHeadline"];
lblSummary.text=[dictionaryObject valueForKey:#"Story"];
lblEdition.text=[dictionaryObject valueForKey:#"Edition"];
//lblStory.text=[dictionaryObject valueForKey:#"FullStory"];
lblDate.text=[dictionaryObject valueForKey:#"PublishDate"];
lblAuthor.text=[dictionaryObject valueForKey:#"Author"];
dispatch_queue_t queue= dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul);
dispatch_async(queue, ^{
NSURL* url = [NSURL URLWithString:[dictionaryObject valueForKey:#"ImagePath"]];
NSData *data = [NSData dataWithContentsOfURL:url];
dispatch_sync(dispatch_get_main_queue(), ^{
UIImageView *imgViewThumb=[[UIImageView alloc]initWithFrame:imgView.frame];
[imgViewThumb setImage:[UIImage imageWithData:data]];
dispatch_async(dispatch_get_main_queue(), ^{
//cell image added below dispath..patching,il change this later..brrrrrr!!
[cell addSubview:imgViewThumb];
//cell.ImagePath.UIImage = imgViewThumb;
});
// [cell addSubview:imgViewThumb];
});
});
//what the heck???
return cell;
}
#pragma mark -methods
-(void)retrieveData{
NSURL * url =[NSURL URLWithString:getDataURL];
NSData *data =[NSData dataWithContentsOfURL:url];
_json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
_newsArray = [[NSMutableArray alloc]init];
for (int i = 0; i < _json.count; i++){
{
NSString * cID =[[_json objectAtIndex:i]objectForKey:#"ID"];
NSString * cName = [[_json objectAtIndex:i]objectForKey:#"MainHeadline"];
NSString * cState =[[_json objectAtIndex:i]objectForKey:#"FullStory"];
NSString * cPopulation =[[_json objectAtIndex:i]objectForKey:#"Edition"];
NSString * cCountry =[[_json objectAtIndex:i]objectForKey:#"PublishDate"];
NSString * cStory =[[_json objectAtIndex:i]objectForKey:#"Story"];
NSString * cAuthor =[[_json objectAtIndex:i]objectForKey:#"Author"];
UIImage *cImage =[[_json objectAtIndex:i]objectForKey:#"ImagePath"];
UIImage *cLogo =[[_json objectAtIndex:i]objectForKey:#"Logo"];
CustomCell2 *myCity = [[CustomCell2 alloc]initWithCityID:cID andCityName:cName andCityState:cState andCityPopulation:cPopulation andCityCountry:cCountry andStory:cStory andImagePath:cImage andAuthor:cAuthor andLogo:cLogo];
[_newsArray addObject:myCity];``
}
//[self.tblView reloadData];
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[self performSegueWithIdentifier:#"detailView" sender:self];
}

An example of better simpler code (in an answer for formatting):
// Current
for (int i = 0; i < _json.count; i++){
{
NSString * cID =[[_json objectAtIndex:i]objectForKey:#"ID"];
NSString * cName = [[_json objectAtIndex:i]objectForKey:#"MainHeadline"];
NSString * cState =[[_json objectAtIndex:i]objectForKey:#"FullStory"];
...
// Simplified
for (NSDictionary *item in _json) {
NSString * cID = item[#"ID"];
NSString * cName = item[#"MainHeadline"];
NSString * cState =item[#"FullStory"];
...
Studying the language documentation can payoff in simpler and clear code.
Also elimination of duplication can reduce simple errors.
