I'm using ASIHttpRequests and an ASINetworkQueue in an iphone app to retrieve some 100k XML files and a lot of thumbnails from a web service. I'd like to cache the requests in the style of NSURLCache. ASI doesn't seem to support caching as is, and I looked at the code and it drops to C to create the requests, so inserting the NSURLCache ...

This is probably obvious, but I'm a bit of a newbie and have spent hours trying to figure this out. In viewDidLoad() I have a call to a function on an MGTwitterEngine object (custom object), with an input. If the request (to Twitter, in this case) is successful, it calls an appropriate delegate method. In viewDidLoad(), it's like thi...
When I get a new image taken by the user with the camera and save its checksum, when the user later reloads that same image from the camera roll, the checksum is different. Could this be because the image saved in camera roll is in JPG format, which is lossy, and therefore its pixels are different? I am trying to use the checksum to dete...
