Question

I have a camera application in which when I click on the camera button the camera opens and user can take picture from camera or from photo-library.

I have done the camera part such that when user clicks on the button the camera opens and he can take a picture. The problem is the picture the user has taken from the camera must be saved into SQLite database. I am stuck in this part. Could anybody help me on how to save image taken from camera ?

If you are using the UIImagePickerController, you can get the image in its imagePickerController:didFinishPickingMediaWithInfo: delegate method. The image you get is an UIImage object.

UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
NSData *data = UIImageJPEGRepresentation(image, 1.0);

Now NSData has a method bytes which returns void*. This will point to a C type array which should play well with SQLite.
