Get max width of uinavigationItem.titleView?

Question

I have a custom titleView that I need to set the max width for. That would be the screen width - width of left item (back title, button or nil) - width of right item (button or nil). How can I determine this?

Thanks.

Answer 1

_segmentedControl.frame = CGRectMake(0, 0, CGFLOAT_MAX, _segmentedControl.frame.size.height);

[self.navigationItem setTitleView:_segmentedControl];

Setting CGFLOAT_MAX as width for the navigationItem title view use the maximum space available between the left item and the right item.

Answer 2

Doesn't the navigationbar set the width to its maximum automatically? I mean, I'm sure the sizeThatFits: method of your custom titleView is called. Maybe this is a good starting point.
