Ask HN: How do App Store webviews work?
It seems the one company that has gotten Webkit views perfect on iOS is Apple. Has the secret sauce behind how they make scrollable areas, smooth pages, etc been revealed anywhere?
(Let's preface this with the following fact: I have very small fingers. These issues lie in the implementation of the software, not in my bratwurst fingers).
Here are a few problems that I've had with it:
1. Touch-canceling doesn't appear to work in the same way as it does for most native apps; the result is that many links are followed by accident.
2. In the Genius tab on the App Store, the tap area for the “Not Interested” button is way too small, and the touch-down feedback is too late. The result is that about 60% of the time when I'm trying to hit that button, I get sent to the page for the app that is in focus.
Now, to be fair, they've actually improved it quite a bit from what it was, it would seem. But it still dwells in the uncanny valley of unhappiness. If this is the state of the art for the sort of thing you are trying to do, than I'd recommend you doing something else.
To put it another way, if Apple, with their massive resources, cannot make a better web view experience than the embarrassing disgrace that is the mobile App Store and iTunes Store, then that may suggest that it is prohibitively difficult (if not impossible) to make web view experiences that any solid engineer can be proud of.
