Usage：

0、Import four frameworks:

CoreMedia.framework、QuartzCore.framework、AVFoundation.framework、ImmageIO.framework

1、Drag "SCCaptureCamera" and "SCCommon" to your project.

2、Import "SCNavigationController.h" and code like this:

    SCNavigationController *nav = [[SCNavigationController alloc] init];
    nav.scNaigationDelegate = self;
    [nav showCameraWithParentController:self];

3、After take a picture, you can call back with delegate or a notification.

a. delegate:

- (void)didTakePicture:(SCNavigationController *)navigationController image:(UIImage *)image

b. notification:

add a notification whose name is kNotificationTakePicture (just search "kNotificationTakePicture" in my demo project)

Finally, set SWITCH_SHOW_DEFAULT_IMAGE_FOR_NONE_CAMERA which is in the file SCCaptureCameraController.m to 0, it is just a joke for the devices which cannot take a picture.
