[SOLVED] Binding UICollectionView with rest API data issue

Binding UICollectionView with rest API data issue

I am trying to grab images from external API and bind it to my UICollectionView & UIImageView cell with in that View. I am able to get the data and print it in the log file. However, I am not able to see the images on my UICollectionView. Here is the code to my data bindings.

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
   ImagesViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];    
  // imagesArray is an array with serialized json data.
  NSDictionary *finalImages = [self.imagesArray objectAtIndex:indexPath.row];    
  NSLog(@"Entering collection view.....");
  [[cell imageViewCell]setImage:[UIImage imageNamed:[finalImages valueForKey:@"link"]]];    
  return cell;
}

The is data is coming in JSON format:

 data
{
  abc: 'abc',
  xyz: 'xyx',
  link: 'link to an online image'
}

Solution

imageNamed is a method to get image from a image file in your bundle (image.png).

In the case you want to get image from URL, download it as Mr Richhard Brown answer or use SDWebImage(set directly with imageView)
