This repository contains two things:
This category adds one public method to NSData instances to make it easy to create data: URIs. You pass in a MIME type (required by the data: URI spec) describing the type of data; it returns an NSURL object containing the URI.
Warning: The returned URI may be long (proportionally to the input data). Be careful where you output it, so as not to bury the user in seemingly garbage text.
The Quick Look APIs require you to specify items to preview or generate thumbnails for as file URLs. I wondered whether you could pass bare data by wrapping it in a data: URI.
The answer is no. The app proves this by experiment.
Aside from demonstrating the use of the various Quick Look APIs, there is nothing else to do with the app. I recommend ignoring it.
