How to find UIImageView Path

Question

In my app I am taking a picture and showing it in an image view.

Now I need the path of that image so I can upload it to a server.

How do I get that path? I try importing ALAsset framework but there is no framework called that my x code (4.2) iOS 5.0

NSData *data = UIImagePNGRepresentation(imagePic.image);
NSString *file = [NSTemporaryDirectory() stringByAppendingPathComponent:@"upload.jpg"];

[data writeToFile:file atomically:YES]; 

[[EPUploader alloc] initWithURL:[NSURL URLWithString:@"myWebSite"]
                       filePath:@"file"
                       delegate:self
                   doneSelector:@selector(onUploadDone:)
                  errorSelector:@selector(onUploadError:)];

This is what I am currently trying.

Also what would be a hard coded path to a photo in an iphone camera roll? "iphone/pictures/myPic" ?? so I can try the upload separate from finding the path.

Please and Thank you

EDIT:

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// Access the uncropped image from info dictionary
image2 = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

// Save image
UIImageWriteToSavedPhotosAlbum(image2, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
imagePic.image = image2;
[picker release];
}

wait why cant you just use the file variable that contains the path where you just saved the image? — Justin Meiners

yeah that would work, you need to save it somewhere to have a path otherwise its only in memory. — Justin Meiners

An image view has no path, it's in memory. You'll have to save the path you get when you return from taking the image. In the delegate method imagePickerController:didFinishPickingMediaWithInfo: you can get the NSURL in UIImagePickerControllerMediaURL which points to the image on disk:

NSURL *imageURL = [info valueForKey:UIImagePickerControllerMediaURL];
