UISearchBar取消按钮颜色？ [英] UISearchBar cancel button color?

问题描述

当我在Interface Builder中将UISearchBar放入我的视图，并将其样式更改为黑色不透明时，取消按钮保持不适合的蓝色/灰色，不会变黑。

When I drop a UISearchBar into my view inside Interface Builder, and change its style to Black Opaque, the cancel button stays unfittingly blue / gray and doesn't become black.

如何使取消按钮变为黑色？

How can I make the cancel button black?

编辑：它的工作方式如下：

It does work like this:

// Assume a UISearchBar searchBar.
NSArray *subviews = [searchBar subviews];

// The index depends on how you configure the searchBar.
UIButton *cancelButton = [subviews objectAtIndex:3];

// Set the style to "normal" style.
[cancelButton setStyle:0];

但是 setStyle：私人框架，所以这可能是一个问题，当提交应用程序到苹果。

But the setStyle: method is from a private framework, so this might be an issue when submitting the app to Apple.

推荐答案

我使用了一些这样的工作，我：

I used some thing like this and worked with me:

[[UIBarButtonItem appearanceWhenContainedIn: [UISearchBar class], nil] setTintColor:[UIColor blackColor]];

它将取消按钮的颜色更改为黑色。

it changed the cancel button color to black.

更新（对于iOS 9.0），不推荐使用 appearanceWhenContainedIn 的方法，而改用 appearanceWhenContainedInInstancesOfClasses ：

Update for iOS 9.0, the method appearanceWhenContainedIn is deprecated, use appearanceWhenContainedInInstancesOfClasses instead:

[[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTintColor:[UIColor blackColor]];

在Swift中：

(UIBarButtonItem.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self])).tintColor = UIColor.blackColor()
