Assignment4:can't get the UIImage displayed in the UIScrollView

[Amy]

I've encountered a problem in assignment4,here is my code
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
NSIndexPath *indexPath = [self.tableView indexPathForCell:sender];
if ([segue.identifier isEqualToString:@"Show Detail"])
{
UITableViewCell *newCell = [self.tableView
cellForRowAtIndexPath:indexPath];//get a new cell
NSURL * photoURL = [FlickrFetcher urlForPhoto:
[self.photoList objectAtIndex:indexPath.row]
format:FlickrPhotoFormatLarge];
NSData *imageData = [NSData dataWithContentsOfURL:photoURL];
UIImage *img = [[UIImage alloc] initWithData:imageData];
[segue.destinationViewController setImage:img];
[segue.destinationViewController
setTitle:newCell.textLabel.text];
newCell.accessoryView = nil;
}

}
in the PhotoOfPlacesTableViewController,when I press on a cell and it
segue to a UIScrollView to show image,but now the problem is that it
just black out when I segue to the ShowPhotoViewController(where the
UIScrollView embedded in),here is the result:

I have two outlets (image view and scrollView) and one public property
(image) in ShowPhotoViewController,in order to show the image,I
put self.imageView.image = self.image; in ViewDidLoad. still can't
work.seek help!!!!!!!!!!!!!!!!!!!!!!!!thanks a lot!!

I just finished assignment 4, and I am having the same problem when running on my device (but not the simulator). So it sounds like the problem is in the FlickrFetcher code, or else on Flickr's end.

your program works fine on simulator??Mine just black out when segue
to imageVC, FlickrFetcher code should be OK,because NSLog the url
string from the program and it open the image you want

I think I am having the same problem except I get black on both the
simulator and on my devices so I have no idea if things are working
correctly or not :-/

er...I've figure that out,put self.imageView.image = image in
viewWillAppear,I firstly put it in viewDidLoad,you can get more
reference from teacher's next demo,photomania.

(pasting this here also for future folks)

Found the error...

The default UIViewController template was inserting a:
- (void)loadView {
// If you create your views manually, you MUST override this
method and use it to create your views.
// If you use Interface Builder to create your views, then you
must NOT override this method.
}

block that was causing the trouble. Since it was not default commented
out, it was overriding and messing up the flow. :-/

Removed that block and it works just great now.
