Getting images using grand central dispatch challenge 5/5

I'm not sure whats wrong with my code, here's my preview:

cannot initialize a parameter of type 'NSData *' with an lvalue of type 'UITableView *'
        cell.imageView.image = [UIImage imageWithData:tableView];
                                                      ^~~~~~~~~
note: expanded from macro 'dispatch_async'
#define dispatch_async(...) th_dispatch_async(__VA_ARGS__);
                                              ^
note: expanded from macro 'dispatch_async'
#define dispatch_async(...) th_dispatch_async(__VA_ARGS__);
                                              ^
note: passing argument to parameter 'data' here
+ (UIImage *)imageWithData:(NSData *)data;
                                     ^
4 errors generated.

And here is my code, I'm on step 5.

LeaderboardViewController.m
#import "LeaderboardViewController.h"

@implementation LeaderboardViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    dispatch_queue_t queue;

    queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
    dispatch_async(queue, ^{
      NSArray *blogPosts = [BlogLoader getRecentPosts];
      dispatch_async(dispatch_get_main_queue(), ^{
        cell.imageView.image = [UIImage imageWithData:tableView];
      });
    });

}

@end

I'm not sure why it took so long to make sense, here's the code:

[tableView reloadData];
