<p>Anybody knows how to wait the response of a http request? In my code, I am doing a http request to an url and then what i need to do, it is to check the http response in order to decide different treatment. I have something like this:</p> <pre><code>-(void)check{ [self fetchURL:@"http://something"]; if(response != nil || [response length] != 0){ do something.... } else{ do something else.... } } -(void)fetchURL:(NSString *)urlWeb{ NSURL *url = [NSURL URLWithString:urlWeb]; NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; [connection scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes]; [connection start]; } - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{ NSLog(@"INSIDE OF didReceiveResponse"); } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{ NSLog(@"INSIDE OF didFailWithError"); } - (void)connectionDidFinishLoading:(NSURLConnection *)connection{ NSLog(@"INSIDE OF connectionDidFinishLoading"); } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{ // Append the new data to receivedData. // receivedData is an instance variable declared elsewhere. NSLog(@"inside of didReceiveData"); response = [NSString stringWithUTF8String:[data bytes]]; NSLog(@"response: %@", response); } </code></pre> <p>I have been trying different options that I have seen around here, but i cant stop the execution of my code and wait for that answer...that means when I check the response of my http request, it always appears empty or with a nil reference... any help how to figure out?? 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.
