可以从UISearchBar中删除背景或边框吗？ [英] Can background or borders be removed from UISearchBar?

问题描述

我想得到这样的东西：

但我无法删除原始背景（我正在使用iOS5）。
然而，似乎Apple做到了：

But I was not able to remove original background (I'm using iOS5). However, it seems Apple did it:

如何创建我想要的内容？
或者，没有选择，我唯一的选择是自定义UITextField？

How can I create what I want? Or, there is no choice and the only alternative I have is customize a UITextField?

感谢您的建议和意见！

编辑：第一次回复后，这就是我得到的：

After first reply, this is what I got:

有没有人如何在不使所有组件半透明变化其alpha值的情况下删除白色内部背景？顺便说一句，我可以用黑色改变白色吗？

Does anyone how can I remove white inner background without making all component semitransparent changing its alpha value? BTW, can I change white color by black color?

推荐答案

试试这个代码，它对我有用

Try this code,It worked for me

for (id img in yourSearchBar.subviews) {
        if ([img isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
           [img removeFromSuperview];    
        }
    }

在上面的代码中，yourSearchBar是你的搜索栏想要删除背景，
并且for循环正在搜索UISearchBar的背景图片

In the above code yourSearchBar is the searchbar from which you want to remove the background, And the for loop is searching for the background image of UISearchBar
