JCDHTTPConnection is a lightweight wrapper for NSURLConnection that provides a simple block callback API.
A JCDHTTPConnection object is initialized with a NSURLRequest object and then executeRequestOnSuccess:failure:didSendData is called on the connection to initiate the asynchronous request. The three callback blocks: onSuccess, onFailure and onDidSendData are all optional.
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://apple.com"]];
JCDHTTPConnection *connection = [[JCDHTTPConnection alloc] initWithRequest:request];
[connection executeRequestOnSuccess:
^(NSHTTPURLResponse *response, NSString *bodyString) {
NSLog(@"SUCCESS: %d: %@", response.statusCode, bodyString);
} failure:^(NSHTTPURLResponse *response, NSString *bodyString, NSError *error) {
NSLog(@"FAILURE: %@", error);
} didSendData:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
// This is not going to be called in this example but it's included for completeness.
NSLog(@"DID SEND DATA: %d", bytesWritten);
}];The repository includes an example Xcode project that fetches URLs and displays the response.
