问题描述
我在.xib中添加了一个导航栏。
我这样做是因为我想定制很多东西。我希望我的导航控制器在该屏幕中使用该导航栏。
I added a Navigation Bar to the .xib.I did that because I want to customize a lot of things of it. I want my navigation controller to use that navigation bar in that screen.
我创建了一个名为navBar的插座并做了：
I created the outlet named navBar and did:
[self.navigationController.navigationBar = navBar;
但它表示navigationBar是只读的。是否可以将我现有的导航控制器与我添加到屏幕的导航栏相关联？
But it says that navigationBar is readonly. Is it possible to link my existing navigation controller with the navigation bar that I added to the screen?
推荐答案
听起来对我来说您可能实际上并不想使用。正如它在参考文档中所述：
It sounds to me that you may not actually want to use a UINavigationBar. As it states in the reference documentation:
因此，如果您计划的自定义设置不仅仅是添加按钮，还可以更改它的颜色/背景，不透明，隐藏等等。你可能最好创建一个感觉导航栏。
So if you're planned customizations go beyond adding buttons, changing it's color / background, opacity, hiding etc.. you might be better off creating a UIView that mimics the look & feel of a navigation bar.
以下是如何为。
它更灵活，实际上很容易做到但是你有很多阅读和测试在你面前:)。
It's far more flexible and actually quite easy to do BUT you've got alot of reading and testing ahead of you :).
如果它只是你想要添加的按钮，你可能最好使用而不是
Just in case if it's just buttons you're thinking of adding you might be better off using UIToolbar instead
