    text
    copied!<p>I'm trying to get a photo thumbnail from the photo album present in Picasa account. I'm using Collection View for displaying the albums with a <code>UIImageView</code> inside the cells to display one of the photos from the album.</p> <p>The problem is, sometimes when I run the code, the cells do not reflect the thumbnails and display a white background but when I put a breakpoint inside the datasource method-- <code>(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath;</code> I can see the images getting set to the image view inside the cells and ultimately the photos on each cell after that.</p> <p>I don't want to use <code>NStimer</code> to hold the Segue. Anyone having suggestions please...</p> <pre><code>- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{ static NSString *identifier = @"Cell"; UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath]; // Configure the cell... GDataEntryPhotoAlbum *albumEntry = [app.albums objectAtIndex:indexPath.row]; if(app.albums.count&gt;albumThumbnails.count) { [[GDataPhotoWrapper sharedGDataPhotoWrapperInstance] setDelegateGDataPhotoWrapper:self]; [[GDataPhotoWrapper sharedGDataPhotoWrapperInstance] fetchImageForSelectedAlbum:albumEntry]; } cell.backgroundView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"photo-frame.png"]]; UILabel *albumTitle = (UILabel*)[cell viewWithTag:200]; albumTitle.text = [[albumEntry title] stringValue]; if(albumThumbnails.count==app.albums.count) { UIImageView *thumbnail = (UIImageView *)[cell viewWithTag:1]; thumbnail.image = (UIImage*)[albumThumbnails objectAtIndex:indexPath.row]; } return cell; } </code></pre>
