This is because the `state` argument of `Core.isScrollable(state:)` is
not always equal to `FloatingPanelController.state` property. Therefore,
the API should pass the `state` property of `Core.isScrollable(state:)`.
The new `floatingPanel(_:shouldAllowToScroll)` delegate method allows the
library user to determine whether the content scrolls or not in certain
state. `Core.isScrollable(state:)` and `LayoutAdpter.offset(from:)` are
added for this feature.
The Logging API document says that `os_log` is one of the legacy logging
symbols. However, this library needs to be supported below iOS 14 so
`log(level:_:)` cannot be used.
`dismissalTapGestureRecognizer` didn't work when the panel is added into UIWindow directly as its subview. This PR fixes this issue and also adds the use case in Samples.app.
This fixes#572 to change the backdrop alpha when the view size or
its size class changes.
The main change is that `true` is passed as a
`forceLayout` parameter into `viewWillTransition(to:with:)` callbacks.
Because it's necessary for the backdrop alpha's update when the view
size or its size class changes.
This also fixes a regression at `9c45c31` commit.
```diff
- layoutAdapter.activateLayout(for: state, forceLayout: true)
+ layoutAdapter.activateLayout(for: state, forceLayout: forceLayout)
```
The behavior before the above change indicates that the method has
worked well even when `forceLayout` is set to `true` in their callbacks.
Additional improvements:
* Format `activateLayout(forceLayout:contentInsetAdjustmentBehavior:)`
* Add `_floor` function for `test_updateBackdropAlpha()`
They were set to `.required - 1` is #359, which fixed#294. However #294
was an issue on `.fitToBounds` content mode. But because of #444 and #515,
if your panel’s content mode is `.static`, their priorities should be set to
`.required` on `.static` content mode.
* Fix FloatingPanelController.invalidateLayout() implementation as following the doc comment
* Revise the doc comments of invalidateLayout() method, layout and behavior properties of FloatingPanelController.
* Add a note in README
* Fix some grammar errors
The backdrop alpha of a panel must be updated only in `Controller.show(animated:completion:)`.
Because that prevents a backdrop flicking just before presenting a panel.
Resolve#466.
* Prevent a possible memory leak at Core.move(from:to:animated:completion:)
* Replace ``self`` with `self`.
* Change `LayoutAdapter.vc` property to an unowned reference
* Prevent a crash at LayoutAdapter.surfaceLocation called in `NumericSpringAnimator.update` closure.
* Allow open access to FloatingPanelDefaultBehavior
* Move the default presenting & dismissing animators
* Add the public initializer of FloatingPanelDefaultBehavior
