Next we need a UIImageView to display the pizza slice UIImage. Create a UIImageView variable and set its 'image' propert

I can not figure out how this is done.

MenuViewController.m 
#import "MenuViewController.h"

@implementation MenuViewController

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    // ... some code omitted for brevity ...
    UIImage *img=[UIImage imageNamed:@"pizza_slice"];]
UIImageView *imageView=[[UIImageView alloc] initWihtImage:img];

    return cell;
}

@end

Sorry, I just now noticed the code challenge. :)

First task: 

UIImage *img = [UIImage imageNamed:@"pizza_slice"];

Second task:

UIImageView *imageView = [[UIImageView alloc] initWithImage:img];

Third task:

cell.accessoryView = imageView;

Your solution contains two errors:

  1. You don't need the final square brackets.
UIImage *img=[UIImage imageNamed:@"pizza_slice"];**]**
  1. ht --> th
UIImageView *imageView=[[UIImageView alloc] initWi**ht**Image:img];

Hi Lei,

You're very close, instead of using the constructor the challenge is asking for you to use the property called image which you can access via the variable imageView that you've created, the end result you should have is.

UIImage *img = [UIImage imageNamed:@"pizza_slice"];
UIImageView *imageView = [UIImageView alloc];
imageView.image = img;

Happy coding and Merry Christmas.

Hi Lei,

You can do this:

UIImage *img = [UIImage imageNamed:@"pizza_slice"];
cell.imageView.image = img;

or this:

UIImage *img = [UIImage imageNamed:@"pizza_slice"];]
UIImageView *imageView = [[UIImageView alloc] initWithImage:img];
[cell addSubview:imageView];

or if you need to a custom disclosure indicator:

UIImage *img = [UIImage imageNamed:@"pizza_slice"];
CGFloat cellHeight = CGRectGetHeight(cell.frame);

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, cellHeight, cellHeight)];
imageView.image = img;

cell.accessoryView = imageView;

Merry Christmas! :)
