My first ever Obj-C hack: Google Reader Notifier
UPDATED: Troels Bay have use another way to do it, please wait for his official build :P
Google Reader Notifier by Troels Bay is a great open source application that provide a desktop notifier for Google Reader, the online feed reader, and also a feed subscriber. As I'm using Camino as my browser, which didn't have a build-in RSS support, I need it even more to subscribe feeds to Google Reader with one click. (not just "notifier" :D )
But when subscribe with preview, if there's a "?" in the URL, the problem is that Google Reader will ignore the part after "?". So that for example my photos on Flickr, "http://api.flickr.com/services/feeds/photos_public.gne?id=76236359@N00&format=rss_200" , will be recognised by Google as "http://api.flickr.com/services/feeds/photos_public.gne".
So I wrote this patch to escape URL before submit to Google.
