CocoaHTTPServer on iOS: set up server so user can download NSData as file

cocoahttpserver, download, hyperlink, ios, nsdata

Solution

All you need to do is to return `HTTPDataResponse` in your HTTPConnection subclass.

If you want an example have a look at the CocoaHTTPServer sample called `DynamicServer` and replace `- httpResponseForMethod: URI:` in `MyHTTPConnection` with something similar to the following:

- (NSObject<HTTPResponse> *)httpResponseForMethod:(NSString *)method URI:(NSString *)path
{
    // Before returning you can analyze the passed path argument and select the correct data object to return...
    return [[HTTPDataResponse alloc] initWithData:placeYourDataInstanceHere];
}

Problem

I want to make the following webpage using `CocoaHTTPServer`: there should be a link to download a file, but the source file must be `NSData` object in memory. As far as I see in samples, there is an easy way to link some file on iPhone to the hyperlink. Is it possible to "link" `NSData`? Would be very thankful for examples.
