Safari renders black lines in between divs on my website at some scales. It is particularly bad when it breaks apart an image that is chopped in two different divs for a button or something.

If an app becomes unresponsive, and is in the background, you can close it manually - but not all users know about this functionality. I know this is a...
How can I get the content (raw/sample data) of an iPod-track? I've seen apps like "Ringtone Designer" and iMovie which can do it, but I have no idea which api they use or what they do. I could imagine that iMovie uses private apis, but "Ringtone Designer" is a third-party app, so it must be possible with the public api-functions. ...
I want to be able to support iOS 3.x users. When I try to set the Base SDK in Project Info, the only SDK that appears is iOS 4.1 and iOS 3.2. How can I add additional SDK's so I can support older users when my app hits the App Store? ...
I'm having a few teething problems with coredata, but feel it would clear things up for me greatly if someone could explain some simple cases to me. I want to put my model into coredata, and at a most simple case take advantage of undo/redo. Thing is, all the examples I see tend to store either strings or integers. What if I have a clas...

I'm working on a image manipulation app that overlays a radial gradient over an image loaded from the photo library. On screen I have a slider to dynamically in/decrease the radius of the radial gradient. I've found the performance on the simulator to be just fine, but on an iPhone 3G or 3GS it is much slower to redraw when moving the s...

I know how to add the UITextView to a custom UITableViewCell--but how might I change the UITableViewCell's height as the user is in the process of typing? I...
