UIImageView background color but not image displaying - ios

Question

I have a UITableViewCell nib file in which there is a UIImageView and a UILabel. I have outlets for both of these to my controller as well as an outlet for the cell itself. I am setting the label and image programmatically, but the image does not show up.
So I went to test it, and even if I set the image itself in the nib file, it does not show up. If I set the background color, it shows up fine. Any ideas? I'm stuck.
It seems to be unrelated to code, in my mind, since it doesn't even work via nib file. But here it is anyway in case it helps somehow.
MyViewController.h
#interface MyViewController : UITableViewController
#property (strong, nonatomic) MyModel *myModel;
#property (strong, nonatomic) NSArray *tableViewCells;
#property (strong, nonatomic) IBOutlet UITableViewCell *tableViewCell;
#property (weak, nonatomic) IBOutlet UILabel *myLabel;
#property (weak, nonatomic) IBOutlet UIImageView *myImage;
#end
MyViewController.m
#interface MyViewController ()
- (void)bindMyModel:(MyModel*)model toView:(UITableViewCell*)view;
- (UITableViewCell*)copyUITableViewCell:(UITableViewCell*)cell;
#end
#implementation MenuViewController
#synthesize myModel = _myModel;
#synthesize tableViewCells = _tableViewCells;
#synthesize tableViewCell = _tableViewCell;
#synthesize myLabel = _myLabel;
#synthesize myImage = _myImage;

{
[super viewDidLoad];
NSMutableArray *cells = [[NSMutableArray alloc] init];
[MyModel loadAndOnSuccess:^(id data, id context) {
self.myModel = data;
for (MyModel *item in self.myModel.items) {
[[NSBundle mainBundle] loadNibNamed:#"TableCellNib" owner:self options:nil];
[self bindMyModel:item toView:self.tableViewCell];
[cells addObject:[self copyUITableViewCell:self.tableViewCell]];
self.tableViewCell = nil;
}
self.tableViewCells = [[NSArray alloc] initWithArray:cells];
} onFail:^(NSString *error, id context) {
NSLog(#"FAIL with error: %#", error);
}];

return [NSKeyedUnarchiver unarchiveObjectWithData: archivedData];

You are trying to use two IBOutlets on your UITableViewController to populate a multitude of UILabels and UIImageViews that are part of the UITableViewCell. You need to create a custom subclass of UITableViewCell and add the IBOutlets to that subclass.
#interface CustomCell : UITableViewCell
#property (weak, nonatomic) IBOutlet UILabel *myLabel;
#property (weak, nonatomic) IBOutlet UIImageView *myImage;
#end
then in your bindMyModel:toView:
- (void) bindMyModel:(MyModel*)model toView:(CustomCell*)view
{
if (view) {
view.myLabel.text = model.myLabelText;
view.myImage.image = model.myImageResource;
}
}
Now you have independent IBOutlets for each of your Cells. You will also need to change some of your bindings as well. This is a fix, but honestly I would rewrite a lot of the code and just use dequeueReusableCellWithIdentifier in your cellForRowAtIndexPath call, and keep a pool of CustomCells that you will reuse, and just set up the myLabel.text and myImage.image in the cellForRowAtIndexPath call.
