A few days ago a client asked me if the transition to the iPhone 4s retina display was a difficult one, development-wise. This made me ask myself whether I should have considered iPhones with high resolution dispays even before the iPhone 4 had been announced - creating artwork with higher resolution, preparing codepaths... (while, of c...

I am using HTML5 video tags in a UIWebview on the iPad, and positioning them as needed using CSS. The key part of these videos is that they are designed to take up part, but not all, of the visible area on the page. When I'm doing this in the "normal" mode of displaying content only to the primary UIScreen, everything works great. Howe...

Anyone have a code snippet that makes a CATextLayer with a bit of text that is clear? Here's the text from Apple's documentation: Note: CATextLayer disables sub-pixel an...

Every one of the 3 UIViewControllers is referenced on the main UIViewController as an IBOutlet. My question is, when does the main UIViewController init those 3 UIViewControllers, in its life cycle (my guess...

I have a native iOS app. It has a UIWebView to read eBooks. I have a search feature in the app that searches for all pages in the eBook that contain the search term.
