How to take a picture and save in SQLite database on iOS

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 came

Answer 1

Now when you opens the camera, you implement the following method

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo {

[[picker parentViewController] dismissModalViewControllerAnimated:YES];
}

in the above method add the following code :--

NSData *imageData = UIImageJPEGRepresentation(img, 1);

then call the method of saving data to database.

Make sure you take the field type as blob in database.

Hope it helps.....

Answer 2

You can create a blob type data field in your database and then save the byte data into that column. But it is a bad practice to save images in database. Instead you can save images in documents directory unless it is very necessary to save images in database.

Answer 3

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.
