Yes, you can position the dot as a fraction of the view’s width. The NSLayoutConstraint method, constraintWithItem:attribute:relatedBy:toItem:attribute:multiplier:constant:, has that multiplier parameter that lets you use a fractional relationship between a superview and its subview. The superview’s right edge will be the width of that view (the screen if its a full width view), so if … Read more
View’s frame determines its location in superview. View’s bounds determines its subviews locations. That means, if you change view’s bounds, its location won’t be changed, but all of its subviews location will be changed. Positive width and height is like you draw a view from upper-left to bottom-right, while negative value is from bottom-right to … Read more

In order to check whether certain view inside another view was touched you can use hitTest. – (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event; In your custom implementation of touchesBegan check every touch in touches set. The point for hitTest method can be obtained using – (CGPoint)locationInView:(UIView *)view; method, where the view is your superView (the one that … Read more
If you set clipsToBounds to true, this will round the corners but prevent the shadow from appearing. In order to resolve this, you can create two views. The container view should have the shadow, and its subview should have the rounded corners. The container view has clipsToBounds set to false, and has the shadow properties … Read more
