ios6 - iPhone keyboard with weird dot -

where dot coming from?:

there dot hidden behind keyboard , highlights blue when pressed (trying press ?123) change keyboard mode.

i have noticed in few placed in app , in ios 6 (also decimal keyboard, 1 can still see dot interferes comma character).

there nothing special doing responders (normal uitextview of uitextfield fields). has idea cause of it?

just exclude popular cause: have rootviewcontroller of key application uiwindow set root navigation controller.

it looks "old"(before ios6) way add dot or return-key uikeyboardtypenumberpad wrong keyboardtype.

something in tutorial: http://www.neoos.ch/blog/37-uikeyboardtypenumberpad-and-the-missing-return-key

have ever used kind of custom keyboard in past? or maybe don't know use it. there category of uitextview have overlooked?

search through project e.g. "@interface uitextfield (" find category.
