Should vertical scrolling be always enabled in iOS screens?
Two of my colleagues think, in iOS apps, vertical scrolling (irrespective of whether the screen has UI elements or content like pictures etc..) should always be enabled on iOS screens. Even when there will never be elements or content out of bounds. They say it always feels like it's a bit janky/wooden, when it does not scroll (and as a consequence bounce).
I for a number of reasons think this kind of modality should only be enabled, when it serves a purpose, otherwise it's a UX antipattern. Some of the reasons would be:
- unnecessary gesture clash with element-specific gestures (for example horizontal slider)
- false promise of something out of bounds (will never happen)
- diminishes the conditions leading to easy muscle memory build up
What would you advise?
