Problems with Programatically Adding UIImageView on iPhone

Question

I'm trying to programatically add dots to a radar screen. The code runs without complaint, but I can't seem to get the dots to show up on screen. I do have a background UIImageView that covers the entire screen, but based on the documentation I expect my new UIImageView to be added to the front (not to mention I've tried bringSubViewToFront:).

Since I'm not sure how to go about debugging this, if someone could show me where I went wrong that would be great.

UIImage *dot;
CGRect dotFrame;
UIImageView *dotView;

// loop through enemies, dropping pins
dot = [UIImage imageNamed:@"enemyDot.png"];
dotFrame = CGRectMake(0, 0, dot.size.width, dot.size.height);
for(location in enemyAgents){

 // add the dot
 dotView = [[UIImageView alloc] initWithFrame:dotFrame];
 dotView.center = CGPointMake(100, 100);
 [self.view addSubview:dotView];
 [dotView release];
 dotView = nil;
}

Do you need to add dot to your dotView? Something like:

dotView.image = dot
