Polishing your screen rotations in iOS

Screen rotations have been a staple of iOS apps since the very beginning. The mark of a great app is one that supports rotations both elegantly and appropriately. You might not believe it, but Apple has continued to add new APIs to allow more control of screen rotations, enabling some cooler effects that weren't possible before. This talk covers a journey I undertook last year to produce fluid rotation animations in an app that only enables landscape support on certain screens: a very common pattern in many iPhone apps. It covers the design mindset, how to plan for it, and some pitfalls that were discovered along the way.
