In Dig Deep Health, my ColdFusion health tracker, workout weights and reps (repetitions) are saved as textual content. This offers better real-world flexibility and lets in customers to go into textual content values like “BW” (Frame Weight) and “Crimson Band” and “Massive Sand Bag”. That stated, the majority of instances will nearly undoubtedly be the getting into of same old, numeric weights and reps. This poses an issue. I might just like the default keyboard for my workout units to be the Numeric keyboard, as this has huge, chonky buttons that make information access more straightforward. However, I nonetheless need the consumer so that you can transfer to the Textual content keyboard for edge-cases. Sadly, iOS does not supply a strategy to transfer from the numeric keyboard again to the textual content keyboard. As such, we now have get a hold of hacky techniques to construct this capability into the consumer interface (UI).

My iOS gadget will alternate the keyboard that it opens in keeping with the inputmode of the centered Enter regulate. However, if we dynamically alternate the inputmode whilst the keyboard is already open, iOS ignores the alternate, leaving the previously-rendered keyboard in view.
Over on StackOverflow, Nate Adams shared an means (that it sounds as if took inspiration from Nike) to briefly concentration any other enter whilst converting the inputmode; then, to re-focus the unique enter with a brand new inputmode during which iOS will render the brand new keyboard.
This provides us a foothold right into a technical workflow; however, we nonetheless have a topic in that the iOS Numeric keyboard does not in truth have a button to get again to the Textual content keyboard. As such, we need to supply a cause within the UI (Person Interface) of the web page.
To experiment with this means, I sought after to create an enter regulate that has a “in-built” button for toggling the inputmode. The Enter and the Button are displayed side-by-side the usage of show: flex; and, try to create a way of unification. Clicking at the button will toggle between decimal and textual content for the inputmode belongings.
CAUTION: That is now not a production-ready resolution – that is only a proof-of-concept. It has a number of problems, now not the least of which is the truth that the buttons will display on Desktop gadgets the place they serve no function. A complete, production-ready resolution would undoubtedly come with some kind of revolutionary enhancement with one thing like CSS media-queries.

As you’ll see, when the consumer clicks the button within the UI, we:
-
Trade the
inputmodeanddevelopmentsettings of the Enter. -
Focal point the hidden temp enter in brief.
-
Re-Focal point the principle visual enter.
And, once we achieve this, we get the next revel in on Chrome (and Safari) for iOS:
As you’ll see, once I hit the Aa/123 button within the regulate, it (turns out to from a Person Revel in point of view) depart the enter centered and in an instant adjustments from one keyboard to any other.
I do not have an Android gadget, so I wasn’t in a position to look if this means works on Android. And, in truth, I believe I take into accout seeing in a screenshot that Android lets in the consumer to change between Numeric and Textual content keyboards, so it most likely is not even important on Android – but one more reason why this is not a production-ready means.
If not anything else, this offers me one thing to consider in the case of imaginable consumer stories.
