I'm doing the extra credit one where you have to display the search results. I've kept the same variable names like blog posts even though it doesn't make much sense keeping them the same! I've seen that [self.blogPosts Count] returns nil and tableView: CellForRowAtIndexPath isn't even called. What have I done wrong? Here's the URL I'm using: https://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=JSON And here's the viewDidLoad method:
-
(void)viewDidLoad { [super viewDidLoad];
NSURL *blogURL = [NSURL URLWithString:@"https://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=JSON"];
NSData *jsonData = [NSData dataWithContentsOfURL:blogURL];
NSError *error = nil;
NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error]; NSLog(@"%@",dataDictionary);
self.blogPosts = [dataDictionary objectForKey:@"results"]; }

{"responseData": {"results": ...
you need to assign the response data to a dictionary first, then access the results key of that dictionary:
NSDictionary *responseData = [dataDictionary objectForKey:@"responseData"];
self.blogPosts = [responseData objectForKey:@"results"];
