如何在iOS中更改键盘背景颜色？

Question

我想知道如何在iOS中以编程方式更改键盘背景颜色？背景通常是灰色的,但我已经看到黑色背景(字母后面).

Answer 1

适合深色背景使用

mytextfield.keyboardAppearance = UIKeyboardAppearanceAlert;

阅读以查找有关UITextInputTraits的更多信息(UIKeyboardAppearanceDark在iOs 7+上使用).

Answer 2

要在全局范围内更改它,您可以在AppDelegate中使用外观代理...我已经在iOS 8中测试了它,Swift:

UITextField.appearance().keyboardAppearance = UIKeyboardAppearance.dark

Answer 3

在iOS 7中,UIKeyboardAppearanceAlert已弃用,因此请改用:

mytextfield.keyboardAppearance = UIKeyboardAppearanceDark;

如果你需要支持早期的iOS和iOS 7,并且你已经创建了必要的宏(根据/sf/answers/373646311/),你可以使用:

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

如果您使用 Interface Builder，则可以在属性检查器中设置键盘外观：
