Block implementation of asyncConnectionWithRequest

NSUrlConnectionWithBlocks

Is a simple category for NSUrlConnection to add blocks for implementing asyncConnectionWithRequest.

Forget about dealing with the delegate methods:

• (void)connectionDidFinishLoading:(NSURLConnection *)
• (void)connection:(NSURLConnection *)_connection didFailWithError:(NSError *)
• (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSHTTPURLResponse *)
• (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)
• (void)connection:(NSURLConnection *)connection didSendBodyData:(NSInteger)bytesWritten totalBytesWritten:(NSInteger)totalBytesWritten totalBytesExpectedToWrite:(NSInteger)totalBytesExpectedToWrite

Instead, use blocks for a cleaner implementation.
All you need is to create a NSURLConnection object as follows:

NSUrlConnection *connection = [NSUrlConnection initWithRequest:(NSURLRequest *)request completionBlock:completionBlock errorBlock:errorBlock uploadPorgressBlock:uploadBlock downloadProgressBlock:downloadBlock];

Provide your blocks, and call [connection start];

The following class methods make it even easier. You don't even need to call start.

• (NSURLConnection *)asyncConnectionWithRequest:(NSURLRequest *)request completionBlock:(NSURLConnectionCompletionBlock)completionBlock errorBlock:(NSURLConnectionErrorBlock)errorBlock uploadPorgressBlock:(NSURLConnectionUploadProgressBlock)uploadBlock downloadProgressBlock:(NSURLConnectionDownloadProgressBlock)downloadBlock;

• (NSURLConnection *)asyncConnectionWithRequest:(NSURLRequest *)request completionBlock:(NSURLConnectionCompletionBlock)completionBlock errorBlock:(NSURLConnectionErrorBlock)errorBlock;

• (NSURLConnection *)asyncConnectionWithURLString:(NSString *)urlString completionBlock:(NSURLConnectionCompletionBlock)completionBlock errorBlock:(NSURLConnectionErrorBlock)errorBlock;
