Question

Apple recommends not searching for hardware version, but for the specific feature in which you are interested.

So how may I detect if there is a front camera on the device to be able to disable some features ?

<代码>[UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] 仅指有一段地方的照相机。

Answer 1

采用这一方法:

+(BOOL)isCameraDeviceAvailable:UIImagePickerControllerCameraDevice cameraDevice

这是一个班级方法,UIImagePickerControllerCamera 装置可以具有两种价值:

例:

if( [UIImagePickerController isCameraDeviceAvailable: UIImagePickerControllerCameraDeviceFront ])
{
   // do something
}

请注意,可在<0>和以后查阅。

Answer 2

In Swift

imagePicker.cameraDevice = UIImagePickerControllerCameraDevice.Front
