Emits keyboard height if the keyboard is visible 22 | /// or `0` if the keyboard is not visible. 23 | let visibleHeight: Driver 24 | 25 | /// Same with `visibleHeight` but only emits values when keyboard is about to show. This is 26 | /// useful when adjusting scroll view content offset. 27 | let willShowVisibleHeight: Driver 28 | ``` 29 | 30 | Use `RxKeyboard.instance` to get singleton instance. 31 | 32 | ```swift 33 | RxKeyboard.instance 34 | ``` 35 | 36 | Subscribe `RxKeyboard.instance.frame` to observe keyboard frame changes. 37 | 38 | ```swift 39 | RxKeyboard.instance.frame 40 | .drive(onNext: { frame in 41 | print(frame) 42 | }) 43 | .disposed(by: disposeBag) 44 | ``` 45 | 46 | ## Tips and Tricks 47 | 48 | - 🔗 **I want to adjust `UIScrollView`'s `contentInset` to fit keyboard height.** 49 | 50 | ```swift 51 | RxKeyboard.instance.visibleHeight 52 | .drive(onNext: { [scrollView] keyboardVisibleHeight in 53 | scrollView.contentInset.bottom = keyboardVisibleHeight 54 | }) 55 | .disposed(by: disposeBag) 56 | ``` 57 | 58 | - 🔗 **I want to adjust `UIScrollView`'s `contentOffset` to fit keyboard height.** 59 | 60 | ```swift 61 | RxKeyboard.instance.willShowVisibleHeight 62 | .drive(onNext: { [scrollView] keyboardVisibleHeight in 63 | scrollView.contentOffset.y += keyboardVisibleHeight 64 | }) 65 | .disposed(by: disposeBag) 66 | ``` 67 | 68 | - 🔗 **I want to make `UIToolbar` move along with the keyboard in an interactive dismiss mode. (Just like the wonderful GIF above!)** 69 | 70 | If you're not using Auto Layout: 71 | 72 | ```swift 73 | RxKeyboard.instance.visibleHeight 74 | .drive(onNext: { [toolbar, view] keyboardVisibleHeight in 75 | toolbar.frame.origin.y = view.frame.height - toolbar.frame.height - keyboardVisibleHeight 76 | }) 77 | .disposed(by: disposeBag) 78 | ``` 79 | 80 | If you're using Auto Layout, you have to capture the toolbar's bottom constraint and set `constant` to keyboard visible height. 81 | 82 | ```swift 83 | RxKeyboard.instance.visibleHeight 84 | .drive(onNext: { [toolbarBottomConstraint] keyboardVisibleHeight in 85 | toolbarBottomConstraint.constant = -1 * keyboardVisibleHeight 86 | }) 87 | .disposed(by: disposeBag) 88 | ``` 89 | 90 | > **Note**: In real world, you should use `setNeedsLayout()` and `layoutIfNeeded()` with animation block.
