推荐答案

你不应该确定是否有摄像头看着模特。这不是未来的证明 - 例如，你不会支持iPad 2的相机。

You should not determine whether there is a camera by looking at the model. This is not future proof - for instance, you would not be supporting the iPad 2's camera.

UIImagePickerController有一个特殊的方法来确定相机是否可用：

UIImagePickerController has a special method to determine whether a camera in available:

+ (BOOL)isSourceTypeAvailable:(UIImagePickerControllerSourceType)sourceType

sourceType为

With sourceType being one of

UIImagePickerControllerSourceTypePhotoLibrary,
UIImagePickerControllerSourceTypeCamera,
UIImagePickerControllerSourceTypeSavedPhotosAlbum
