I suspect you could use techniques described in <a href="https://stackoverflow.com/questions/556814/changing-the-size-of-the-uisearchbar-textfield/1436362#1436362">this post</a>

Modifying the code presented there slightly, you subclass UISearchBar:

<pre><code>@interface SearchBar : UISearchBar {
}
@end
</code></pre>

Then in your implementation:

<pre><code>- (void)layoutSubviews {
 UITextField *searchField;
 NSUInteger numViews = [self.subviews count];
 for(int i = 0; i &lt; numViews; i++) {
 if([[self.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) {
 searchField = [self.subviews objectAtIndex:i];
 }
 }
 if(!(searchField == nil)) {
 searchField.textColor = [UIColor redColor];
 }

 [super layoutSubviews];
}
</code></pre>

I haven't tested either the original post's code or this code, but looks like it ought to work.

blocks|key|2101145|text|您可以执行以下操作:只需从SearchBar获取searchField属性，然后更改其textColor属性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2101146|UITextField+*searchField+=+[searchbar+valueForKey:@"_searchField"];

You can do the following: Just get the searchField property from the SearchBar, and then change its textColor property.

<pre><code>UITextField *searchField = [searchbar valueForKey:@"_searchField"];
searchField.textColor = [UIColor redColor]; //You can put any color here.
</code></pre>

That's it! Now you manipulate the textField in any way possible.

With iOS 11 the search bar is expected to become part of the navigation bar which, as you might expect, adds all kinds of new "features."

I think it's a bug but I found that I needed to do the following to change the text (and cancel button) colour:

<pre><code>self.searchController.searchBar.barStyle = UISearchBarStyleMinimal;
[[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]]
 setTintColor:[UIColor whiteColor]];
</code></pre>

I found that the bar-style, when left to "default," would make the text black no matter the tint colour, etc. When set to either Minimal or Prominent the text was visible.

blocks|key|193242|text|对于iOS11，我发现这是可行的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|193243|在navigationItem中设置searchController后，搜索文本在黑色上显示为黑色。为了让它变白，我必须这样做：|offset|length|style|CODE|193244|searchController.searchBar.barStyle+=+.blackTranslucent|code-block|syntax|javascript|193245|这是唯一对我有效的方法。我的应用程序有一个透明的导航栏，可以让背景渐变显示出来，我猜SearchBar会采用这种外观，因为我对UISearchBar的外观设置基本上被忽略了，只有一个例外：|193246|UISearchBar.appearance().tintColor+=+UIColor.red|193247|这会使Cancel按钮和文本插入光标变为红色。占位符文本为浅灰色。|193248|请注意：UISearchBar.appearance().barStyle+=+.blackTranslucent不起作用-它必须在实例上设置。这对搜索栏也没有明显的影响(它仍然像导航栏一样是透明的)；它只是使搜索文本变为白色。|193249|entityMap^0|0|1|E|I|G|0|0|1R|B|0|0|0|4|1H|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@$D|Y|E|Z|F|G]|$D|10|E|11|F|G]]|9|@]|A|$]]|$1|H|3|I|5|J|7|12|8|@]|9|@]|A|$K|L]]|$1|M|3|N|5|6|7|13|8|@$D|14|E|15|F|G]]|9|@]|A|$]]|$1|O|3|P|5|J|7|16|8|@]|9|@]|A|$K|L]]|$1|Q|3|R|5|6|7|17|8|@]|9|@]|A|$]]|$1|S|3|T|5|6|7|18|8|@$D|19|E|1A|F|G]]|9|@]|A|$]]|$1|U|3|-4|5|6|7|1B|8|@]|9|@]|A|$]]]|V|$]]

For iOS11, I found this worked:

After setting the <code>searchController</code> into the <code>navigationItem</code>, the search text was black on black. To make it white, I had to do:

<pre><code>searchController.searchBar.barStyle = .blackTranslucent
</code></pre>

It was the only thing that worked for me. My app has a transparent navigation bar to let the background gradient show through, and I am guessing the SearchBar takes on that appearance since my appearance settings for <code>UISearchBar</code> were largely ignored with one exception:

<pre><code>UISearchBar.appearance().tintColor = UIColor.red
</code></pre>

This made the Cancel button and the text insertion cursor red. The placeholder text was light gray.

Note that: <code>UISearchBar.appearance().barStyle = .blackTranslucent</code> did not work - it had to be set on the instance. This also had no visible effect on the search bar (it was still transparent like the navigation bar); it just made the search text white.

blocks|key|2970680|text|在iOS+11的navigationItem中设置searchController后，我发现尝试通过UIAppearance为UITextField中的任何UISearchBar设置textColor没有任何影响，但是一个自定义外观属性(它只是调用常规textColor)工作得很好。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2970681|//+Implement+a+custom+appearance+property+via+a+UITextField+category

After setting the <code>searchController</code> in the <code>navigationItem</code> for iOS 11, I found that attempting to set the <code>textColor</code> via <code>UIAppearance</code> for any <code>UITextField</code> within a <code>UISearchBar</code> had no affect, but a custom appearance property that simply called the regular <code>textColor</code> worked just fine.

<pre><code>// Implement a custom appearance property via a UITextField category
@interface UITextField (SearchBarTextColor)

@property (nonatomic, strong) UIColor * textColorWorkaround UI_APPEARANCE_SELECTOR;

@end

@implementation UITextField (SearchBarTextColor)

- (UIColor *)textColorWorkaround {
 return self.textColor;
}

- (void)setTextColorWorkaround:(UIColor *)textColor {
 self.textColor = textColor;
}

@end
</code></pre>

And then use as follows: 

<pre><code>UITextField *textFieldProxy = [UITextField appearanceWhenContainedInInstancesOfClasses:@[UISearchBar.class]];
textFieldProxy.textColorWorkaround = UIColor.lightGrayColor;
</code></pre>

P.S. The same trick helped me color the seemingly inaccessible labels of <code>UIDatePicker</code> and <code>UIPickerView</code>

Browsed the documentation and I couldn't find anything to change the color of UISearchBar. Does anybody know how to change it? There isn't any textColor property :/

Thx
