iOS Question Allow only number input into TextView?

[Arf]

I want to keep the DEFAULT keyboard as there seems no other way to ensure a DONE button appears on the keyboard, but I also want to restrict the entry of anything except numbers in my TextView.

Is there any method I can use to do this?

Or, how can I test (without getting an exception) whether the TextView contains a dignified number like 582.33 as opposed to some trouble-causing riffraff like 123g9*,x?

Thanks

The numbers keypad doesn't show an enter button. However you can add such a button yourself. To the layout or above the keyboard (https://www.b4x.com/android/forum/threads/input-accessory-views.51000/).

You can use IsNumber to test whether the string is a valid number.
