Courses Plus Student 2,669 PointsThanks Natacha S. for the prompt reply.
This is what i am doing in the - (void)viewDidLoad method. and I am still not able to get what am i doing wrong.
NSURL *blogURL=[NSURL URLWithString:@"https://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=JSON"];
NSData *jsonData=[NSData dataWithContentsOfURL:blogURL];
// NSLog(@"%@",jsonData);
NSError *error=nil;
NSDictionary *dataDictionary=[NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];
NSLog(@"%@",dataDictionary);
self.blogPosts=[dataDictionary objectForKey:@"results"];
The app is working fine in the simulator, i mean there are no errors. but no data is showing on the table view in simulator.
Please help...

As you can see above you have a dictionary which contains a key called
responseData
within that you have theresults
. So you can't directly access the results. You would need to use the methodvalueForKeyPath
.self.blogPosts = [dataDictionary valueForKeyPath:@"responseData.results"];
