To tint a UIView, add another subview on top of it with the same frame and an alpha transparency set.

For example let's say your container type view is called containerView, you'd do as follows:

CGRect overlayFrame = containerView.frame;
UIView *overlayView = [UIView alloc] initWithFrame:overlayFrame];
overlayView.alpha = 0.5f;
overlayView.color = [UIColor blackColor];

[containerView addSubview:overlayView];

This gives you a semi transparent (0.5f) black tint that will give a tint like appearance to all the subviews underneath.
