IOS Can I rename the image file name before saving it to the iPhone device gallery from the application?

Question

Hey, I'm new to the iPhone, and I'm trying to create a gallery app. Basically, I want to need to save all the captured images to a specific folder, for example, the new album "My_App Images" associated with our application name in the iPhone device gallery, it works for me, but I am having problems changing the name image file, I do not know that you can specify the file name? Using iPhoto, I am currently getting the image file name as "IMG_0094.jpg", can we change it with any other file name, for example, "Anyfilename.png", programmatically?

here is my code for saving images to a specific album:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
{    
    [self.library saveImage:image toAlbum:@"My_App Images" withCompletionBlock:^(NSError *error) {
        if (error!=nil) {
            NSLog(@"Image saving error: %@", [error description]);
        }
    }];

    [picker dismissViewControllerAnimated:NO completion:nil];
}

,

// Build NSData in memory from the btnImage...
NSData* imageData = UIImageJPEGRepresentation(image, 1.0);

// Save to the default Apple (Camera Roll) folder.   
[imageData writeToFile:@"/private/var/mobile/Media/DCIM/100APPLE/customImageFilename.jpg" atomically:NO];
