    I'm really new to cocoa, so please be gentle ;)

    I have been given the chance to develop an iPhone app, so I'm trying to learn cocoa and objc, which is all great. I've just found out that I need to have the ability to sign your name in the app I'm making and I haven't got the first clue where to look for this. Can someone point me in the right direction please? I think it has something to do with quartz, but I'm damned if I can find anything that relates to what I'm looking at!

    thanks

    If you look in the sample code in the dev centre, there's a paint program that should fit what you're after perfectly :)

    now, I might be totally barking up the wrong tree here (too many tree metaphors?), but can I have Open GL running in a view? This is the sort of thing I'm thinking of:

    [​IMG]

    I also want to be able to temporarily save that as a png, read the image data into a sqlite table then destroy the png (it has to be done this way - the data needs to be sync'd with a web server and I figure the easiest way to do this is in plain text.)

    If anyone is willing to talk to me in words of 1 syllable about this, I'd really appreciate it. I'm definitely getting the hang of this, but I'm coming from a web background and it's so different!
