Hello, I'm building an app which includes a number of image sequences (5 sequences with about 80 images each). It runs nicely in the iPhone simulator, but causes my iPhone to reboot when I test it. By the way, each png image is about 8k in size. Has anyone successfully built a similar app? Am I using too many resources for the iPhone to...

Hello, For the application I am writing, I need to access some other applications' items, for which Applescript seems the best way to go. I have been using the Appscript framework, which worked well, because it allowed me to thread it and not make my app lock up when an Applescript was taking a while. However, now I am attempting to m...

Is there a way to know when the dismissModalViewControllerAnimated is initiated and when it is completed (such as the idiom for viewWillAppear and viewDidAppear)? Unlike other animations, this one doesn't seem to have a delegate that tells you. ...
Hey guys, I'm trying to differentiate between two (or more) UITouch objects on the iPhone. Specifically, I'd like to know the order in which the touches occurred. For instance, in my -touchesBegan:withEvent: method I get an NSSet of UITouch objects. Now I can find out how many touches there are, but, which object represents which finge...
