显然，有些人已经能够弄清楚如何通过 SDK 访问 iPhone 摄像头（例如《Spore Origins》）。如何才能做到这一点？
您需要使用UIImagePickerController类，基本上：
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = pickerDelegate
picker.sourceType = UIImagePickerControllerSourceTypeCamera
The pickerDelegate上面的对象需要实现以下方法：
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
词典info将包含原始图像和编辑后的图像的条目，键控为UIImagePickerControllerOriginalImage and UIImagePickerControllerEditedImage分别。 （看https://developer.apple.com/documentation/uikit/uiimagepickercontrollerdelegate https://developer.apple.com/documentation/uikit/uiimagepickercontrollerdelegate and https://developer.apple.com/documentation/uikit/uiimagepickercontrollerinfokey https://developer.apple.com/documentation/uikit/uiimagepickercontrollerinfokey更多细节）
