HI,

Have u tried this method

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

If you want to save the image to your device Photo Album

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

Finally to know the save is Successful or not use this method

- (void)imageSavedToPhotosAlbum:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo {
        NSString *message;
        NSString *title;
        if (!error) {
        title = NSLocalizedString(@"SaveSuccessTitle", @"");
        message = NSLocalizedString(@"SaveSuccessMessage", @"");
        }
 else {
        title = NSLocalizedString(@"SaveFailedTitle", @"");
        message = [error description];
      }
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title 
                                           message:message
                                           delegate:nil
                                           cancelButtonTitle:@"OK"
                                           otherButtonTitles:nil];
                                           [alert show];
                                           [alert release];

}

Otherwise If you are retriving large number of data(such as images etc.), you can implement Coredata in your project to do further complex operations.
