The information provided is taller than an iPhone screen so they're all in a UIScrollView (itself inside a UIView) that allows you to swipe up and down to see everything.

I'm developing a static library that will be distributed to other developers, who may need debug statements. So I have several levels of logging. In order to avoid constant appearance of if(loggingLevelCurrentlySet >= loggingLevelWantedForThisInstance){ NSLog(@"log this"); } I created a set of logging function wrappers. A simp...

Is there an equivalent of MonoTouch.Dialog, but for native Objective C apps? MonoTouch.Dialog automatically generates UITableView settings-style interfaces based on model metadata, or via a simple API. I've been experimenting with building apps with MonoTouch, but I've found the app startup time currently unacceptable, so I'm trying to...

Something I'm not very clear on is whether I should/could use interface builder to create reusable game sprites. For example, if I have a ball that I want to create an indeterminate amount of at run time, should I be creating a nib file (and either attaching graphics in IB or drawing them in drawRect) with it's own viewcontroller class a...
