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)
