我的问题是我的NavigationItem中的RightBarButtonItem在视图第二次出现后消失了.第一次加载视图时，它会正确显示，但是第二次完全消失.

My problem is that my RightBarButtonItem, in my navigationItem, disappears after the view appears a second time. The first time the view loads, it displays properly, but the second time it disappears completely.

该按钮在viewWillAppear中的初始化如下:

The button is init'd in viewWillAppear as such:

UIBarButtonItem *optionsButton = [[UIBarButtonItem alloc] initWithCustomView:roundedButton]; self.navigationItem.rightBarButtonItem = optionsButton;

我记得叫超级

我只再次触摸导航控制器:

I only touch my navigation controller once more:

Any ideas how this might be happening?

推荐答案

您可以使用类别在导航栏上添加自定义图像.通过在导航栏上创建类别来覆盖drawRect方法.在Google上搜索，您会找到它.如果没有让我知道.我帮你做.

you can use a category to add custom image on navigation bar. Override drawRect method by creating a category on navigation bar. Search on google you will find it. If not let me know. I'll do it for you.
