Table 5-1  Dictionary keys for the UIRequiredDeviceCapabilities key

Key	Description
accelerometer	Include this key if your app requires (or specifically prohibits) the presence of accelerometers on the device. Apps use the Core Motion framework to receive accelerometer events. You do not need to include this key if your app detects only device orientation changes.
armv6	Include this key if your app is compiled only for the armv6 instruction set. (iOS 3.1 and later)
armv7	Include this key if your app is compiled only for the armv7 instruction set. (iOS 3.1 and later)
auto-focus-camera	Include this key if your app requires (or specifically prohibits) autofocus capabilities in the device’s still camera. Although most developers should not need to include this key, you might include it if your app supports macro photography or requires sharper images in order to perform some sort of image processing.
bluetooth-le	Include this key if your app requires (or specifically prohibits) the presence of Bluetooth low-energy hardware on the device. (iOS 5 and later.)
camera-flash	Include this key if your app requires (or specifically prohibits) the presence of a camera flash for taking pictures or shooting video. Apps use theUIImagePickerController interface to control the enabling of this feature.
front-facing-camera	Include this key if your app requires (or specifically prohibits) the presence of a forward-facing camera. Apps use the UIImagePickerControllerinterface to capture video from the device’s camera.
gamekit	Include this key if your app requires (or specifically prohibits) Game Center. (iOS 4.1 and later)
gps	Include this key if your app requires (or specifically prohibits) the presence of GPS (or AGPS) hardware when tracking locations. (You should include this key only if you need the higher accuracy offered by GPS hardware.) If you include this key, you should also include the location-services key. You should require GPS only if your app needs location data more accurate than the cellular or Wi-fi radios might otherwise provide.
gyroscope	Include this key if your app requires (or specifically prohibits) the presence of a gyroscope on the device. Apps use the Core Motion framework to retrieve information from gyroscope hardware.
location-services	Include this key if your app requires (or specifically prohibits) the ability to retrieve the device’s current location using the Core Location framework. (This key refers to the general location services feature. If you specifically need GPS-level accuracy, you should also include the gps key.)
magnetometer	Include this key if your app requires (or specifically prohibits) the presence of magnetometer hardware. Apps use this hardware to receive heading-related events through the Core Location framework.
microphone	Include this key if your app uses the built-in microphone or supports accessories that provide a microphone.
opengles-1	Include this key if your app requires (or specifically prohibits) the presence of the OpenGL ES 1.1 interfaces.
opengles-2	Include this key if your app requires (or specifically prohibits) the presence of the OpenGL ES 2.0 interfaces.
peer-peer	Include this key if your app requires (or specifically prohibits) peer-to-peer connectivity over a Bluetooth network. (iOS 3.1 and later)
sms	Include this key if your app requires (or specifically prohibits) the presence of the Messages app. You might require this feature if your app opens URLs with the sms scheme.
still-camera	Include this key if your app requires (or specifically prohibits) the presence of a camera on the device. Apps use the UIImagePickerControllerinterface to capture images from the device’s still camera.
telephony	Include this key if your app requires (or specifically prohibits) the presence of the Phone app. You might require this feature if your app opens URLs with the tel scheme.
video-camera	Include this key if your app requires (or specifically prohibits) the presence of a camera with video capabilities on the device. Apps use theUIImagePickerController interface to capture video from the device’s camera.
wifi	Include this key if your app requires (or specifically prohibits) access to the networking features of the device.
