Responding to events from an array of UIImageViews inside scrollview ios5 - ipad

Question

For my iPad app, I am programmatically creating several UIImage views that I display on the screen. The code looks basically like this:
for(ModelObject *model in ModelsList){
//create a UIImage view from the model object
UIImageView *icon = [[UIImageView alloc] initWithFrame:model.icon_frame];
icon.image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:model.icon_path ofType:#"png"]];
//add the imageview to a mutable array to keep track of them
[myImageViews addObject:icon];
// add the view as a subview
[self.view addSubview:icon];
}
So now I have a bunch of icons displayed on the screen. But I would like to intercept touch events from the UIImageViews that I created programmatically, so that it calls some other method, preferably with an argument containing the sender's id or some other distinguishing information that I can use to determine which UIImageView was touched.
What is the best practices way of accomplishing this?
I am new to iOS so recommended reading would also be greatly appreciated.

Please provide any applicable feedback, as I have no idea if this is common practice or even a decent way of doing things...
So basically what I did was keep a dictionary of ids that maps between the view object and the model objects, and then I look up the id of the sending view and find the appropriate model object, (I will then use that model object to load another view)
The code looks like this:
// in header
#property(nonatomic, retain) NSMutableDictionary *icons_to_models
// after creating a UIButton called icon
[icon setBackgroundImage:model.image forState:UIControlStateNormal];
[icon addTarget:self action:#selector(tappedIcon:) forControlEvents:UIControlEventTouchUpInside];
NSNumber *key = [NSNumber numberWithUnsignedInt:[icon hash]];
[icons_to_models setObject:model forKey:key];
...
//match sender to the icon that was pressed and
-(void)tappedIcon:(id)sender{
NSNumber *key = [NSNumber numberWithUnsignedInt:[sender hash]];
ModelObject *model = [icons_to_models objectForKey:key];
NSLog(#"tapped on: %#", model.name);
}
