Adding Image To UIImageView In Separate Class

I have two view controllers: Products View Controller and Detail View Controller. When the user taps a cell on a UITableView, it will transition to the Detail View Controller. The Detail View Controller has a UIImageView in it names imageEq. I'm trying to set the image in the Products View Controller. This is how I'm doing it:

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"pushDetailView"])
    {
        DetailViewController *dvc;
        UIImage *pic = [UIImage imageNamed:@"HorseImage.png"];
        [dvc.imageEq setImage:pic];
        NSLog(@"Pic should be set");
}
........ (non relevant code)
}

I connected the outlets, copied the image into the project, and made sure all my spelling is correct. When I run this, the image view remains blank and has never loaded the image. I can't figure out why not, this all looks perfect to me. Does the above code look flawed in any way?

If you replace your DetailViewController pointer to this code below, it should work for you. 

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"pushDetailView"])
    {
        UIImage *pic = [UIImage imageNamed:@"HorseImage.png"];

        [[segue destinationViewController] setDetailImage:pic];

        NSLog(@"Pic should be set");
}

Hope this helps, Thanks Jim.

EDIT

Add the following property in your DetailViewController's header file

@property (strong, nonatomic) UIImage *detailImage;

And in the viewDidLoad of your DetailViewController's .m file, add the following

self.imageEq.image = _detailImage;

I hope this updated answer help.

Also change

[[segue destinationViewController] setImageEq:pic];

to

[[segue destinationViewController] setImageEq:[[UIImageView alloc] initWithImage:pic]];
