OS X and iOS use different AirDrop protocols and are currently not interoperable. AirDrop in OS X operates over Wi-Fi, whereas the iOS implementation utilizes both Wi-Fi and Bluetooth.
On OS X, AirDrop is available through a special folder in Finder, and as of OS X 10.8.1 can be accessed through the menu option Go > AirDrop or by pressing⇧ Shift+⌘ Cmd+R. The feature can be accessed on iOS through the Control Center introduced in iOS 7.
