如何在 iOS 中更改键盘背景颜色？

Question

I would like to know how to change the keyboard background color programmatically in iOS? The background is normally grey but I have already seen black background (behind letters).

Answer 1

For the dark background use:

mytextfield.keyboardAppearance = UIKeyboardAppearanceAlert;

Read to find more information about UITextInputTraits (use UIKeyboardAppearanceDark at iOS 7+).

Answer 2

要全局更改它，您可以在 AppDelegate 中使用外观代理...我已经在 iOS 8、Swift 中对其进行了测试：

UITextField.appearance().keyboardAppearance = UIKeyboardAppearance.dark

Answer 3

In iOS 7, UIKeyboardAppearanceAlert is deprecated, so use this instead:

mytextfield.keyboardAppearance = UIKeyboardAppearanceDark;

If you need to support both earlier iOSes and iOS 7, and you've created the necessary macros (per https://stackoverflow.com/a/5337804/588253 ), you can use this:

mytextfield.keyboardAppearance = (SYSTEM_VERSION_LESS_THAN(@"7.0") ? UIKeyboardAppearanceAlert : UIKeyboardAppearanceDark);

Answer 4

更新到 swift 3.0

let textFieldAppearance = UITextField.appearance() textFieldAppearance.keyboardAppearance = .dark //.default//.light//.alert

Answer 5

If you're using Interface Builder, you can set keyboard look in the Attributes Inspector:

Answer 6

SWIFT 4+：在 AppDelegate 中

UITextField.appearance().keyboardAppearance = .dark

Answer 7

今天只需使用myTextField.keyboardAppearance = .dark

Answer 8

Swift 5+ (TextView)

 textView.keyboardAppearance = .dark

Answer 9

In Objectve-C

For Dark Keyboard

[UITextField appearance].keyboardAppearance = UIKeyboardAppearanceDark;

For Light keyboard

[UITextField appearance].keyboardAppearance = UIKeyboardAppearanceLight;

You can define this in AppDelegate to handle this globally.
