Re: Continuously running daemon process CFConstantStringRefs build up over time

Since you're writing a daemon, you'll need to handle autorelease-pool creation and draining manually (something that's normally handled by NSApplication in standard AppKit apps.) Perhaps objects are autoreleased and placed in the root autorelease pool (that you might be creating in main() or the li

This looks great, so I can store everything on the thumbdrive without having to set up symlinks on the machines I want to use, and I don't have to reference the drive itself as I can take the location from the app bundle, perfect. ( a bit like web relative links I suppose,) sorry, I did mea

QTMovie raw data

Hi, I guess the answer to my simple question is no, but figured I better ask before I go digging elsewhere. I have a QTMovie, initialized with a MP3 file downloaded from a remote server (i.e -initWithURL:). Is it possible to extract the raw data from the QTMovie object, so I can save the MP3 in i

I mean that you would continue using -initWithURL: but feed it a custom URL scheme. Hopefully QTMovie will load that scheme using standard NSURLConnection internally. Whereupon you can write a custom protocol handler that grabs data from correct scheme. On 1 Oct 2010, at 17:38, slasktrattena...

Would probably use the numbered replacement format. In english, your format string would be: @"%...@... %...@... %...@..." And in the other language, it'd be: @"%...@... %...@... %...@..." Then you'd use it like normal: NSString * translated = [NSString stringWithFormat:format, value1, value
