For the 13.1 release of our NUCLiOS product we added a LOT of features. So many in fact that its actually quite easy to overlook some of them. So, today i'm going to talk about one of my favorite features added to the IGGridView: Infinite Scrolli…
I've talked about all the tricks you can do with images before, even about how to take screen shots of a particular UIView. However, today i'm going to dive into that just a little bit more and show you how you can take that screen shot at different…
Yes, this may be an edge case, but it is a problem that you may run into one day. For example, say you're writing an App that requires you to accept any sort of random json or xml. While you could just consume them in dictionary format, it maybe not actually…
I've said this before, and i'll probably keep saying it, the UIScrollView is very powerful and awesome. Its so powerful that we build our IGGridView control by deriving from it. Even Apple wrote their UITableView the same way.

Given a UIImage, in some cases you may want to have the image split. For example, say you wanted to create a Flipboard or Paper like interface, where you have a screen shot of a UIVIew, and you want to have the appearance of it folding.
