You should implement -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event method of your UIViewController

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    if([event touchesForView:view1] != nil) 
        //View1 touched
    else if ([event touchesForView:view2] != nil) 
        //View2 touched
    else if ([event touchesForView:view3] != nil) 
        //View3 touched
    else if ([event touchesForView:view4] != nil) 
        //View4 touched 
}

You can tag your view by setting its 'tag' property and in your (IBAction)touched:(id)sender you inspect the tag value like

if (((UIView*)sender).tag == 1) {
    //Do something for the view with tag value 1
}
