Retrieving the UIImage of a TTPhotoViewController - iphone

Question

I have a TTPhotoViewController subclass working nicely. I need to be able to give the option of saving the image downloaded to the user's saved photos directory. I am having problems actually retrieving a UIImage object.
After looking through the API I have seen that TTPhoto (which is one of the properties of the view controller) doesn't actually contain a UIImage to use. However, within the API there is a TTImageView class which has a UIImage property. TTPhotoView derives from TTImageView and there is one of these in my view controller class called "PhotoStatusView". However when I access this I do not get a UIImage back.
Any ideas?

Check this site out add save to album functionality
Here is the code from the site:
_clickActionItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:
UIBarButtonSystemItemAction
//TTIMAGE(#"UIBarButtonReply.png")
target:self action:#selector(clickActionItem)];
UIBarButtonItem* playButton = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:
UIBarButtonSystemItemPlay target:self action:#selector(playAction)] autorelease];
playButton.tag = 1;
UIBarItem* space = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:
UIBarButtonSystemItemFlexibleSpace target:nil action:nil] autorelease];
_toolbar = [[UIToolbar alloc] initWithFrame:
CGRectMake(0, screenFrame.size.height - TT_ROW_HEIGHT,
screenFrame.size.width, TT_ROW_HEIGHT)];
_toolbar.barStyle = self.navigationBarStyle;
_toolbar.autoresizingMask = UIViewAutoresizingFlexibleWidth
| UIViewAutoresizingFlexibleTopMargin;
NSString *searchCaption = #"Photo from networked";
NSRange range = [[_centerPhoto caption] rangeOfString:searchCaption];
if (range.location == NSNotFound) {
_toolbar.items = [NSArray arrayWithObjects:
space, _previousButton, space, _nextButton, space,_clickActionItem, nil];
[_innerView addSubview:_toolbar];
}else{
_toolbar.items = [NSArray arrayWithObjects:
space, _previousButton, space, _nextButton, space, nil, nil];
[_innerView addSubview:_toolbar];
}
and this
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
}
- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex
{
if(6 == actionSheet.tag)
{
if(0 == buttonIndex)//save page
{
NSLog(#"photo: %#", [_centerPhoto URLForVersion:TTPhotoVersionLarge]);
NSURL *aUrl = [NSURL URLWithString:[_centerPhoto URLForVersion:TTPhotoVersionLarge]];
NSData *data = [NSData dataWithContentsOfURL:aUrl];
UIImage *img = [[UIImage alloc] initWithData:data];
NSLog(#"photo:class %#", [img class]);
UIImageWriteToSavedPhotosAlbum(img, nil, nil, nil);

You should try using:
UIImage *image = [[TTURLCache sharedCache] imageForURL:URL];
