Is there any way to set the notification handler for Document folder, where when the file is created in the document folder,my callback should get triggerd where i will move the file from document folder to Photo Gallery.

Answer 1

You can do it with this:

UIImageWriteToSavedPhotosAlbum (image, self, @selector(image:didFinishSavingWithError:contextInfo:) , nil);

the callback method signature is:

- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo
