ios UISearchBar 取消按钮颜色？

UISearchBar cancel button color?

提问by cactus

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.

当我将 UISearchBar 放入 Interface Builder 中的视图中，并将其样式更改为 Black Opaque 时，取消按钮会保持不合适的蓝色/灰色并且不会变成黑色。

How can I make the cancel button black?

如何使取消按钮变黑？

EDIT: It does work like this:

编辑：它确实像这样工作：

// 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];

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

但是该setStyle:方法来自私有框架，因此在将应用程序提交给 Apple 时这可能是一个问题。

I used some thing like this and worked with me:

我使用了这样的东西并与我一起工作：

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

it changed the cancel button color to black.

它将取消按钮颜色更改为黑色。

Updatefor iOS 9.0, the method appearanceWhenContainedInis deprecated, use appearanceWhenContainedInInstancesOfClassesinstead:

iOS 9.0更新，该方法appearanceWhenContainedIn已弃用，请appearanceWhenContainedInInstancesOfClasses改用：

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

And in Swift 3:

在 Swift 3 中：

UIBarButtonItem.appearance(whenContainedInInstancesOf:[UISearchBar.self]).tintColor = UIColor.black

The problem with your solution is that the code is assuming that the objectAtIndex:3 is the cancel button. Not only does this generate a compiler warning, but also if you are displaying the Cancel button programmatically (for example using [searchBar setShowsCancelButton:YES], you risk crashing the application.

您的解决方案的问题在于代码假设 objectAtIndex:3 是取消按钮。这不仅会生成编译器警告，而且如果您以编程方式显示“取消”按钮（例如使用[searchBar setShowsCancelButton:YES]，您可能会导致应用程序崩溃。

A simpler solution is to set the style of the whole search bar in ViewDidLoad(), using:

一个更简单的解决方案是在 ViewDidLoad() 中设置整个搜索栏的样式，使用：

searchBar.tintColor = [UIColor colorWithWhite:0.3 alpha:1.0];

this overrides the style set in the Interface Builder BUT also changes the colour of the Cancel button to be same colour as the whole bar (although it doesn't let you set the style of Cancel button independently, unfortunately.

这会覆盖在界面生成器中设置的样式，但也会将取消按钮的颜色更改为与整个栏的颜色相同（尽管不幸的是，它不允许您独立设置取消按钮的样式。

Try this and see: (I tested below code with Swift 4.1 - Xcode 9.3-beta4)

试试这个看看：（我用 Swift 4.1 - Xcode 9.3-beta4测试了下面的代码）

@IBOutlet weak var sbSearchBar: UISearchBar!

sbSearchBar.tintColor = UIColor.red
sbSearchBar.showsCancelButton = true
sbSearchBar.barTintColor = UIColor.blue
sbSearchBar.tintColor = UIColor.red

if let buttonItem = sbSearchBar.subviews.first?.subviews.last as? UIButton {
    buttonItem.setTitleColor(UIColor.yellow, for: .normal)
}

In Swift 4.2

在 Swift 4.2 中

let appearance = UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self])
appearance.setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor(named: "goldColor")!], for: .normal)

This works for me. Thanks @Tim Semple

This is an updated version of Hossam Ghareeb's answer abovefor Swift 3:

这是上面针对 Swift 3的Hossam Ghareeb 回答的更新版本：

UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self] ).tintColor = UIColor.red

But this will not override appearance if it has already been set elsewhere for UIBarButtonItem.

但是，如果已经在别处为 UIBarButtonItem 设置了外观，则这不会覆盖外观。

For example, in my navbar controller I had to change this:

例如，在我的导航栏控制器中，我不得不改变这一点：

UIBarButtonItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName:UIColor.white], for: UIControlState.normal)

To this for the solution above to work:

为此，上述解决方案可以正常工作：

UIBarButtonItem.appearance(whenContainedInInstancesOf: [UINavigationBar.self] ).setTitleTextAttributes([NSForegroundColorAttributeName:UIColor.white], for: UIControlState.normal)

for iOS 10:

对于 iOS 10：

UISearchBar.appearance().tintColor = UIColor.red //cancel button color
UISearchBar.appearance().barTintColor = UIColor.blue //background button color

I have taken Benjamin'sanswer and combined it with safe Arraylookup to produce a short, but safe functionalversion:

我已经采用了Benjamin 的答案，并将其与安全Array查找相结合，以生成一个简短但安全的功能版本：

searchController.searchBar.tintColor = UIColor.whiteColor()
(searchController.searchBar.subviews[safe: 0]?.subviews as? [UIView])?
    .filter({
extension Array {
    subscript(safe index: Int) -> T? {
        return indices(self) ~= index ? self[index] : nil
    }
}
.isKindOfClass(UITextField)})
    .map({
let view: UIView = self.searchBar.subviews[0] as UIView
let subViewsArray = view.subviews

for subView: UIView in subViewsArray {
    if let cancelButt = subView as? UIButton{
        cancelButt.setTitleColor(UIColor.white, for: .normal)         
    }
}
.tintColor = .lightGrayColor()})

This results in coloring the Cancel button white and the cursor when typing gray. Otherwise it would be white and thus not seen. The searchControlleris an object of type UISearchController. If anybody wants to use it inside the results controller, replace it with self.

这会导致在键入灰色时将取消按钮和光标着色为白色。否则它会是白色的，因此看不见。的searchController是类型的对象UISearchController。如果有人想在结果控制器中使用它，请将其替换为self.

The implementation of the safe:subscript is nkukushkin'sanswer:

safe:下标的实现是nkukushkin的回答：

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

[[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTitleTextAttributes:@{NSForegroundColorAttributeName: [UIColor whiteColor]} forState:UIControlStateNormal];

[[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTitleTextAttributes:@{NSForegroundColorAttributeName: [UIColor whiteColor]} forState:UIControlStateDisabled];

[[UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTitleTextAttributes:@{NSBackgroundColorAttributeName: [UIColor whiteColor]} forState:UIControlStateNormal];

Click on Search bar and set the tintcolor under view from Interface Builder.

单击搜索栏并在界面生成器的视图下设置色调颜色。

The above code also fixed my UI issues for iOS 13 and iPhone X. I included this code in my AppDelegate.mclass in didFinishLaunchingWithOptionsfunction, so that the changes could be done in the whole app.
