Description of Change
The current
ScrollViewimplementation on iOS contains a middle layer between theScrollViewand the actual content.The reason hides behind device tests, where the
ScrollViewis being hosted by a standardUIViewwhich knows nothing about MAUI.So it won't invoke the handler's
GetDesiredSizeandPlatformArrange.So they've crated this hack, where the container view has its parent's Handler (
ScrollViewHandler) asICrossPlatformLayout.This way, if you invalidate the container view it triggers a forced layout on its parent: the
ScrollView.This is an absolute hack and creates an useless resize loop.
In addition to that, CV2 is not properly reporting the desired size when unbounded, so this PR brings back and improves some code we had in CV1 to measure the content size when the CV is smaller than the constraints.
