我如何将navigationItem.titleView放在左右栏按钮项的后面

Question

Is it possible to have the titleView to be behind the left and right bar button item on a navigation bar? I've set my titleView to have a width of 320 and it covers the left and right bar button item. I wonder if there is a way to move it to the back?

Answer 1

In my experiments, it appears that the titleView is always drawn after (above) the left and right bar button items. You could try spelunking the view hierarchy and using sendSubviewToBack: , provided that the title view is ever made part of the navigation bar's hierarchy.

If you can render the effect you're trying to achieve into an image, you could set that as the backgroundImage of the navigation bar, but this may not be practical.

Remember that you'll likely need to account for interface rotation in any case, since the navigation bar height (on iPhone) goes from 44px in portrait to 32px in landscape).
