Hi all, I have a strange bug in my CoreData-Application (sql store). I received bug reports where the program throws an exception "Could not fulfill a fault". This happens while loading the document. The only way I can reproduce this problem is using the "Time Profiler" in Instruments while l

Re: UI Design on iPad

Hi Bing, Quartz should work most of the time, and you usually *don’t* have to move away from UIKit. I really recommend that you don’t ditch UIKit — check out videos from WWDC 2010 and see how far one can go. Without UIKit, you lose all the features that come for free, which is almost always t

Re: UI Design on iPad

Don't give up on UIKit. You will find you can do alot with UIKit. I have used UIKit extensively for several large custom projects with great results. To see the UIKit used to its fullest look at: Disney Second Screen: Tron Edition - http://itunes.apple.com/us/app/disney-second-screen-tron/id426

Re: UI Design on iPad

To second that, we use only UIKit and you can customize stuff very easily. Buttons are probably the best example where you can make it look like anything. There are some controls you can't customize (UISwitch), but there are open source alternatives that are fully customizable - all written usin

Re: UI Design on iPad
