Answer 1

To work with camera

if ([UIImagePickerController isSourceTypeAvailable:
     UIImagePickerControllerSourceTypeCamera]) {
    UIImagePickerController* imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.delegate = self;
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePickerController.mediaTypes = [NSArray arrayWithObjects:
                                        (NSString *) kUTTypeImage,
                                        (NSString *) kUTTypeMovie, nil];
    [self presentViewController:imagePickerController animated:YES completion:nil];    }
