如何在UINavigationItem.rightBarButtonItem(或leftBarButtonItem)上添加多个UIBarButton? [英] How do you add more than one UIBarButton on UINavigationItem.rightBarButtonItem (or leftBarButtonItem)?

问题描述

我已经尝试过这种方法/黑客: http://blog.blackwhale.at/2009/06/uibuttons-in- uinavigationbar/

I have tried this approach/hack: http://blog.blackwhale.at/2009/06/uibuttons-in-uinavigationbar/

问题是这留下了淡淡的接缝.我尝试将嵌套工具栏的背景图像设置为我捕获到的应该是的图像.那没用.图像未应用.我还尝试过使用嵌套的UINavigationBar，但这似乎没有用.

The problem is this leaves a faint seam. I tried setting the background image of the nested toolbar to an image I captured of what it should be. That didn't work. The image was not applied. I have also tried using a nested UINavigationBar and that didn't seem to work.

我已经在多个iPhone应用程序中看到了这一点.有人知道吗?

I have seen this done in several iPhone apps. Does anyone know how?

我希望按钮看起来像普通的UIBarButtonItems，并能够使用UIBarButtonSystemItemAdd，UIBarButtonSystemItemRefresh之类的系统样式.我提供的链接可以做到这一点，但是您可以看到一个淡淡的接缝，因为它是嵌套在导航栏中的UIToolbar.

I want the buttons to look like normal UIBarButtonItems and be able to use system styles like UIBarButtonSystemItemAdd, UIBarButtonSystemItemRefresh. The link I provided does this except you can see a faint seam because it is a UIToolbar nested in the navigationbar..

请不要提及这违反了《人机界面指南》. (我们知道).

Please don't mention this breaking the Human Interface Guidelines. (We know).

推荐答案

要摆脱UIToolbar的背景(缝")，请创建UIToolbar的子类并重写(void)drawRect:(CGRect)rect方法.将其保留为空白，您的UIToolbar将不再具有背景.

To get rid of the background ('seam') of a UIToolbar, create a subclass of UIToolbar and override the (void)drawRect:(CGRect)rect method. Leave that blank and your UIToolbar will no longer have a background.

只需在我自己的项目中使用它，就可以很好地工作.在以下评论中找到了此内容: http://osmorphis. blogspot.com/2009/05/multiple-buttons-on-navigation-bar.html

Just used this in my own project and worked great. Found this in the comments of: http://osmorphis.blogspot.com/2009/05/multiple-buttons-on-navigation-bar.html
