UISegmentedControl自定义背景图片 [英] UISegmentedControl custom background image

问题描述

我有UINavigationBar设置为图像 - 一些木材纹理。我想插入UISegmentedControl有4个按钮在那个吧。按钮应具有相同的纹理，略有变化的色调。

I have UINavigationBar setup as image - some wood texture. I want to insert UISegmentedControl with 4 buttons on that bar. Buttons should have same texture with slightly changed tint.

一种解决方法是更改​​按钮背景颜色的tint alpha，以便背景中的纹理可以通过，但是当我在IB中为色调设置alpha时，保存值，它总是返回值1.

One solution would be to change tint alpha of buttons background color, so that texture in background can get trough, but as I set alpha for tint in IB it doesn't save value, it always gets back to value 1.

我无法得到UISegmentedControl显示背景图片，所以终于放弃了，决定搜索帮助...
所需的效果是iBooks应用程序中的一个，在导航栏中有按钮。
任何链接或小帮助将不胜感激。

I cant get UISegmentedControl to show background image, so finally gave up and decide to search for help... Effect that is desired is one in iBooks app, with buttons in Navigation Bar. Any link or small help would be appreciated..
