Is this for iOS or Mac OS? I've used Grand Central Dispatch and [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]];
The second example is synchronous. There is also: NSData *response_NSData = [NSURLConnection sendSynchronousRequest:my_NSURLRequest returningResponse:&my_NSURLResponse error:&my_NSError]; and sendAsynchronousRequest:queue:completionHandler: Loads the data for a URL request and executes a handler block on an operation queue when the request completes or fails. + (void)sendAsynchronousRequest:(NSURLRequest *)request queue:(NSOperationQueue *)queue completionHandler:(void (^)(NSURLResponse*, NSData*, NSError*))handler Look up the above in the NSURLConnection Class Reference And also this, but disregard the older stuff. http://www.raywenderlich.com/4295/multithreading-and-grand-central-dispatch-on-ios-for-beginners-tutorial Here is my GDC stuff. - (void)viewDidLoad { NSLog(@"In viewDidLoad"); [super viewDidLoad]; //NSString * const kRootURLString = @"http://10.6.2.137/";; NSURL *wordsURL = [NSURL URLWithString:@"http://localhost/~zav/Offices.txt?";]; NSURL *myUrl = [NSURL URLWithString:URLstring]; // dispatch_async(kBgQueue, ^{ NSData* data = [NSData dataWithContentsOfURL: myUrl]; // THIS IS WHAT YOU WANT Ariel ** dispatch_sync(kBgQueue, ^{ NSData* data = [NSData dataWithContentsOfURL: myUrl]; // doing a sync dispatch here - we want to wait for it to finish [self performSelectorOnMainThread:@selector(fetchedData:) withObject:data waitUntilDone:YES]; }); // Uncomment the following line to display an Edit button in the navigation bar for this view controller. // self.navigationItem.rightBarButtonItem = self.editButtonItem; } ... - (void)fetchedData:(NSData *)responseData { NSLog(@"In fetchedData"); NSLog(@" "); // log URL data NSString* newStr = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; NSLog(@"%@", newStr); } Practice on a few simple cases until you find a method that you like. Note that I haven't checked my code for any leaks. This is old play code from 2 weeks ago.
