How to give a name to a saved Image from the imagePickerController - iphone

Question

I'm using an imagePickerController to replace my existing images inside my view. The function works within the same IB-file. However I'd like to load the chosen image in another IB-File as well. I think that the solution is to give a name to the image when saved. After it is saved I'd like to call the image (by name) from my memory within my other IB-file.
Here's a snippit of code I'm using within the photopicker IB-file
-(IBAction)setPhoto{
image1.image = fotoView.image;
}
-(IBAction)getCameraPicture:(id)sender
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsImageEditing = YES;
picker.sourceType = (sender == takePictureButton) ? UIImagePickerControllerSourceTypeCamera :
UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self presentModalViewController: picker animated:YES];
[picker release];
}
-(IBAction)selectExitingPicture
{
if([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypePhotoLibrary])
{
UIImagePickerController *picker= [[UIImagePickerController alloc]init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:picker animated:YES];
[picker release];
}
}
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage : (UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
[picker dismissModalViewControllerAnimated:YES];
fotoView.image = image;
NSData* imdata = UIImagePNGRepresentation ( image );
UIImage* im8 = [UIImage imageWithData:imdata];
UIImageWriteToSavedPhotosAlbum(im8, nil, nil, nil);
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *) picker
{
[picker dismissModalViewControllerAnimated:YES];
}
within my other class I'd like to call this image by means of:
if (#some condition){
UIImage *img = [UIImage imageNamed:#"Name of the image.png"];
[image1 setImage:img];
}
Help is greatly appreciated

Method for image picking and saving it to the directory:
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo {
[picker dismissModalViewControllerAnimated:YES];
NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *pngFilePath = [NSString stringWithFormat:#"%#/MyName.png",docDir];
NSData *data = [NSData dataWithData:UIImagePNGRepresentation(image)];
[data writeToFile:pngFilePath atomically:YES];
}
Lateron you can call it by using:
NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *pngFilePath = [NSString stringWithFormat:#"%#/MyName.png",docDir];
UIImage *image = [[UIImage alloc] initWithContentsOfFile:pngFilePath];
