Thank you in advance!.

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *cellIdentifier=@"Cell";

    CollectionVIewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
    ;
    CollectionVIewCell *feederCell = (CollectionVIewCell*)[_availableFilters objectAtIndex:indexPath.row];



    cell.labelDisplay.text=feederCell.filterName;
    NSLog(@"selected =%@",cell.labelDisplay.text);
    if (feederCell.isSelected) {
        UIImageView *imageView=[[UIImageView alloc]init];
        //process string name
        NSString*filePath =[NSString stringWithFormat:@"%@.png",feederCell.filterName];
        NSArray* words = [filePath componentsSeparatedByCharactersInSet :[NSCharacterSet whitespaceCharacterSet]];
        filePath=[words componentsJoinedByString:@""];
        cell.FilePath=filePath;
        //image
        UIImage *image = [UIImage imageNamed:filePath];
        [imageView setFrame:CGRectMake(0, 0, image.size.width, image.size.height)];
        [imageView setImage:image];
        [cell setIconDisplay:imageView];//setting the image that won't set
    }else if(!feederCell.isSelected){
        UIImageView *imageView=[[UIImageView alloc]init];
        NSString*filePath =[NSString stringWithFormat:@"%@.png",feederCell.filterName];

You need to add the UIImageView as a subview. Otherwise it exists but isn't displayed.
