How do I obtain the height of UINavigationBar.navigationItem programmatically?
提问by ChrisP
I am creating a custom UIToolbarto use as a UIViewin the UINavigationBar.navigationitem.titleViewproperty. I would like to size the toolbar height to that of the .navigationitem by obtaining the current height of the .navigationitem rather than hard code it. Is there a way to obtain the height value?
我创建一个自定义UIToolbar为使用UIView的UINavigationBar.navigationitem.titleView属性。我想通过获取 .navigationitem 的当前高度而不是硬编码来将工具栏高度调整为 .navigationitem 的高度。有没有办法获得高度值？
