RxKeyboard响应式的 iOS 键盘组件

RxKeyboard 是一个韩国人开发的响应式的 iOS 键盘组件，效果如下图所示：

示例代码：

RxKeyboard 提供两种驱动方式：

/// An observable keyboard frame.

let frame: Driver<CGRect>



/// An observable visible height of keyboard. Emits keyboard height if the keyboard is visible

/// or `0` if the keyboard is not visible.

let visibleHeight: Driver<CGFloat>



/// Same with `visibleHeight` but only emits values when keyboard is about to show. This is

/// useful when adjusting scroll view content offset.

let willShowVisibleHeight: Driver<CGFloat>

使用 RxKeyboard.instance 来获取单例实例

RxKeyboard.instance

订阅 RxKeyboard.instance.frame 来侦听键盘帧的变化

RxKeyboard.instance.frame

  .drive(onNext: { frame in

    print(frame)

  })

  .disposed(by: disposeBag)
