I add a view as subview of my uiviewcontroller like this:

 

// into my ViewController:
UIImageView *imView =[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"img.jpg"]];
imView.frame = CGRectMake(2, 46, 1020, 720);
[self.view addSubview:imView];

now, with another button I wish remove the imView from the subview chain..how can I do to do this??thanks

You can call this method, which belongs to UIView (and UIImageView inherits from UIView)

UIView - (void)removeFromSuperview
