The clever folk over at Kintek have posted a handy system-to-system guide for anyone working in the mobile development space. This metaphor overview quickly references how items like buttons, switches, one-of-n selection and other common interface items are expressed by default in the target arenas.
You'll find items from Android, iOS 6 and iOS 7 listed side by side, so you can quickly review their visual presentation. Resource links take you to developer documentation. It's nicely done and well worth checking out.
