Question

i have a jpg file in my database,
how can i used json/php build in my Xcode project?
my jpg link in php format like this:
[{"photo_path":"photo_path.jpg,"title":"test topic""]}
i know when i build "title" part,i can use NSString format,
but in "photo_path.jpg" part,did i use NSString also??
#property (nonatomic, strong) NSString * title;
#property (nonatomic, strong) NSString * photo_path;
#property (strong, nonatomic) IBOutlet UITextView *detaillabel;
#property (strong, nonatomic) IBOutlet UIImageView *photolabel;
and here is my json.m part:
- (void) retrieveData
{
NSURL * url = [NSURL URLWithString:getDataURL];
NSData * data = [NSData dataWithContentsOfURL:url];
json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
HomeArray = [[NSMutableArray alloc]init];
for (int i = 0; i < json.count; i++)
{
NSString * titletopic = [[json objectAtIndex:i] objectForKey:#"title"];
NSString * detailinfo = [[json objectAtIndex:i] objectForKey:#"detail"];
NSString * photo = [[json objectAtIndex:i] objectForKey:#"photo_path"];
NSString * dateinfo = [[json objectAtIndex:i] objectForKey:#"date"];
HomeDetail * home2 = [[HomeDetail alloc]initWithTitle:titletopic
andDetail:detailinfo
andPhoto_path:photo
andDate:dateinfo];
[HomeArray addObject:home2];
}
[self.myTableView reloadData];
}

You need to store the path/url of your image in your database. By path I mean local path (if the image is stored locally) or URL if it's somewhere on the interwebz.
Fetch that URL whichever way pleases you (JSON is fine), and make your way through the JSON to retrieve the NSString of that URL.
( you appear to have that all done already, in your NSString *photo
Though i suggest you rename "photo" with photoPath or something more clear because the photo name strongly suggests it's already an image, which it isn't yet :)
Then simply apply this where you need the UIImage object:
NSURL *url = [NSURL URLWithString:photo];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *img = [[UIImage alloc] initWithData:data cache:NO];
You can then add it to an imageview using setImage: or .image
