Change image in a UIImageView in a different class

I have two views, One is the Gameview and the other and a menu where I would like the user to select a button and it will change the image view in GameView to that image.

I has this bit of code for doing this but It doesn't seem to be working...

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqual:@"goToGameViewsSegue"]) {
        MainMenuView_4inch_White *dest = [segue destinationViewController];
        dest.imageView = CloudyBlue; //set the image in your view as the image in the settings view
        [dest.imageView setImage:[UIImage imageNamed:@"Cloudy-Eye-Blue.png"]];
        NSLog(@"Image should have been changed here.. How come it didn't?");

    }
}

I did check over all of the connection and if the segues was connected and it is all good so mustn't be that.

Since you're changing the UIImageView object in the destination view controller, you need to make sure it's added as a subview to the correct superview.

 dest.imageView = CloudyBlue; 
 [dest.view addSubview:CloudyBlue]; // add it to the correct view and set the frame, depending on what you need.

But for the sake of keeping your code clean and modular, I recommend doing this kind of thing inside the destination view controller. Having one view controller mess with another's views is error prone and I don't recommend it.

For example, you could have this in your destination view controller:

- (void)setImage:(UIImage *)image 
{
     // 1) set up self.imageView, if necessary

     // 2) set the image
     self.imageView.image = image;     
}
