将键盘外观属性设置为 UIKeyboardAppearanceDark。

示例

[textField setKeyboardAppearance:UIKeyboardAppearanceAlert];

来自文档

//
// UIKeyboardAppearance
//
typedef NS_ENUM(NSInteger, UIKeyboardAppearance) {
    UIKeyboardAppearanceDefault,          // Default apperance for the current input method.
    UIKeyboardAppearanceDark NS_ENUM_AVAILABLE_IOS(7_0),
    UIKeyboardAppearanceLight NS_ENUM_AVAILABLE_IOS(7_0),
    UIKeyboardAppearanceAlert = UIKeyboardAppearanceDark,  // Deprecated
};
