如何确定UINavigationController中工具栏的高度? [英] How to determine height of the toolbar in UINavigationController?

问题描述

我有一个带有UINavigationController呈现的工具栏的视图.

I have a view with a toolbar presented by a UINavigationController.

当我处理UIKeyboardWillShowNotification时，我将整个屏幕向上滚动键盘高度. 问题是显示键盘时，底部的工具栏没有，所以我只需要向上滚动屏幕(keyboard.height-工具栏.height).

When I am handling UIKeyboardWillShowNotification, I'm scrolling the entire screen upwards by the height of the keyboard. The thing is when the keyboard is shown, the bottom toolbar is not, so I need to scroll the screen upwards by only (keyboard.height - toolbar.height).

但是如何获取工具栏的高度?

But how to get the height of the toolbar?

谢谢

推荐答案

您只需要检查工具栏框架即可.

You just should check the toolbar frame.

self.navigationController.toolbar.frame.size.height

当然，只有在您具有导航控制器的情况下，它才有效...

Of course, it only works if you have a navigation controller...
