UIRequiredDeviceCapabilities 指定程序需要那些設備

	Key	說明
	telephony(電話）	Include this key if your application requires (or specifically prohibits) the presence of the Phone application. You might require this feature if your application opens URLs with the tel scheme
	wifi	Include this key if your application requires (or specifically prohibits) access to the networking features of the device.
	sms	Include this key if your application requires (or specifically prohibits) the presence of the Messages application. You might require this feature if your application opens URLs with the sms scheme.
	still-camera	Include this key if your application requires (or specifically prohibits) the presence of a camera on the device. Applications use the UIImagePickerController interface to capture images from the device’s still camera.
	auto-focus-camera	Include this key if your application requires (or specifically prohibits) auto-focus capabilities in the device’s still camera. Although most developers should not need to include this key, you might include it if your application supports macro photography or requires sharper images in order to do some sort of image processing.
	front-facing-camera	Include this key if your application requires (or specifically prohibits) the presence of a forward-facing camera. Applications use the UIImagePickerController interface to capture video from the device’s camera.
	camera-flash(相機閃光燈)	Include this key if your application requires (or specifically prohibits) the presence of a camera flash for taking pictures or shooting video. Applications use the UIImagePickerController interface to control the enabling of this feature.
	video-camera	Include this key if your application requires (or specifically prohibits) the presence of a camera with video capabilities on the device. Applications use the UIImagePickerController interface to capture video from the device’s camera.
	accelerometer(加速度計)	Include this key if your application requires (or specifically prohibits) the presence of accelerometers on the device. Applications use the classes of the Core Motion framework to receive accelerometer events. You do not need to include this key if your application detects only device orientation changes.
	gyroscope(陀螺儀)	Include this key if your application requires (or specifically prohibits) the presence of a gyroscope on the device. Applications use the Core Motion framework to retrieve information from gyroscope hardware.
	location-services(定位服務)	Include this key if your application 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.)
	gps	Include this key if your application requires (or specifically prohibits) the presence of GPS (or AGPS) hardware for greater accuracy when tracking locations. If you include this key, you should also include the location-services key. You should require GPS only if your application needs more accurate location data than the cell or Wi-fi radios might otherwise allow.
	magnetometer(磁力儀)	Include this key if your application requires (or specifically prohibits) the presence of magnetometer hardware. Applications use this hardware to receive heading-related events through the Core Location framework.
	microphone	Include this key if your application uses the built-in microphone or supports accessories that provide a microphone.
	opengles-1	Include this key if your application requires (or specifically prohibits) the presence of the OpenGL ES 1.1 interfaces.
	opengles-2	Include this key if your application requires (or specifically prohibits) the presence of the OpenGL ES 2.0 interfaces.
	armv6	Include this key if your application is compiled only for the armv6 instruction set. (iOS v3.1 and later.)
	armv7	Include this key if your application is compiled only for the armv7 instruction set. (iOS v3.1 and later.)
	peer-peer	Include this key if your application requires (or specifically prohibits) peer-to-peer connectivity over Bluetooth. (iOS v3.1 and later.)
