All works usually perfect with a mobileContainer displaying text fields, one under the other. However, when there are too many fields (more than 15), when selecting a field at the bottom, the whole entry field with the container starts moving up - large containers: field and container totally disappear at the moment of field selection…
Again, the whole constraint thing via code is very confusing, especially since all seems well designed with the auto layout…
Normally here you would place the MobileContainer inside a ScrollableArea. This is a bit of a pain to code, but works.
I have moved to GraffitiPagePanels and GraffitiTabPanels that set up the scrolling of your MobileContainers automatically, so this is an alternative approach.
