Pretty simple question: when doing some pretty intense drawing with CoreGraphics on the iPhone, how can I specify the pixel format to get optimal performance? Is the format that I get from the context via UIGraphicsGetCurrentContext per definition the best one? I know that RGB565 is supposed to be the fastest to use in OpenGL. Does that ...
Everything works fine on the simulator, but I gete EXC_BAD_ACCESS when I try to load my app on the device. I've put in a bunch of NSLogs to try and catch where it happens, but the log statements are never reached. Also, the UI doesn't load. So, seems the problem is happening before any of my code is reached. I tried a clean build, no luc...

I am receiving a "CoreData could not fulfill a fault for ..." error message when trying to access a new attribute in a new data model. If I work with new data I'm ok, but when I attempt to read existing data I get the error. Do I need to handle the entity differently myself if the attribute isn't in my original data?

I would like to have a UITextField which aligns to the bottom and to the right. I would like the majority of text to be on the bottom line with putting extra words on the next line as needed.

The problem is that the UITextView "text" property doesn't save all the rows in the textView (after touching "return"). I tried print the TextView object and the textView.text, and they're different. Does anybody know how (after edi...
Hi, I'm searching for a way to create a menu in an iPhone app that allows buttons to rotate around a center point. To put this in visual terms: the buttons would be planets and the center is the sun. this would allow the user to 'spin' the buttons around the circular path. ** an actual example of this would be the Poynt menu for the...
