Re: Troubles with CollectionView and IKImageBrowserView

Thank you for your tips! But I didn't understand everything. Do you 
tried this in a sampleproject which you can send me?

If I initialize the imageBrowser in my MYNSCollectionViewItem and set 
the datasource, the datasource methods will now be called correctly. 
Thank you. But it seems that the IKImageBrowserView which is displayed 
will not display anything, even if I reload the imageBrowser data 
manually:

- (id)initWithCoder:(NSCoder *)decoder {
   imageBrowser = [[IKImageBrowserView alloc] init];
   [imageBrowser setDataSource:self];    
   return self;
}


// 
-------------------------------------------------------------------------
//    numberOfItemsInImageBrowser:view
// 
-------------------------------------------------------------------------
- (int)numberOfItemsInImageBrowser:(IKImageBrowserView*)view
{
   MyObject *representedObject = [self representedObject];
   return [representedObject.myImages count];
}

// 
-------------------------------------------------------------------------
//    imageBrowser:view:index:
// 
-------------------------------------------------------------------------
- (id)imageBrowser:(IKImageBrowserView *) view itemAtIndex:(int) index
{
   MyObject *representedObject = [self representedObject];
   return [representedObject.myImages objectAtIndex:index];
}

- (IBAction)refreshView:(id)sender {
   [imageBrowser reloadData];
}

Regards...Manu

You mean my customized NSCollectionView, didn't you?
