Description
Description
On iOS, it's not possible to align content with the collection view item background, if a background colour is set.
This image for an example of what I mean:
This was produced with this Xaml:
This is only an issue on iOS, not on Android.
I've included a renderer in the iOS solution that hacks a fix in for this. After the fix, the item is displayed correctly:
I believe the issue is caused by the fact that the rendered content is given a bounds with an x of -1 and a y of -1.
Steps to Reproduce
Run the app
Expected Behavior
Background and accent are aligned
Actual Behavior
Background and accent are misaligned
Uncomment out the renderer attribute on iOS to see a hack that works around the bug
