HOWEVER, it does not always work this way:
- PadKeys will never be shown for password fields, due to security restrictions in iOS.
- Individual apps may choose to deliberately disable third-party keyboards for reasons of their own. For example banking apps often disable them everywhere.
- If you have a company-managed device, third-party keyboards may be locked out of managed apps.
- Sometimes, due to iOS bugs, some apps don't "get the message" right away that there is a new keyboard available. Ironically it's often Apple's own apps, like Safari and Mail, that have this problem.
We encourage reporting this problem directly to Apple, either via http://www.apple.com/feedback/ipad.html or via their bug reporter if you have a developer account.
