Error in view when I opened the keyboard


I have a login screen that sometimes when I click the input it does not open the keyboard and mess my layout.
Before click on the input.

After click.

Thank you.

It’s a “known issue” of ios 7.1. My understanding is that the web-view is trying to re-center itself around the input box whenever you tap on it.

Thanks for the reply!
What do you think I should do to overcome this difficulty?
