Trying to debug a jqMobi app in a Safari browser on an iPhone 4 (IOS6).
When I touch in a text input field, the on-screen keyboard appears, and the screen behind it zooms in so that the text input field pretty much fills the screen. This is normal iPhone behaviour and not a problem.
However, when I hit the "return" or "done" button, the screen stays zoomed in, with apparently no way of getting it back to normal.
I understand from the answer to question jqmobi. on ios (ipod) when input field focused content moves up that I should be able to detect the event when the keyboard closes, but I don't know what to call to tell iPhone Safari to go back to its normal zoomed-to-100% state.
Update: I've found a workaround, which is to add a "maximum-scale=1" to the meta name=viewport directive, but the trouble with that is that you now can't do any of the usual screen resizing manually.
