I still cannot wait for Google to release their keyboard for ios, until then I'll stay stock.
On the TouchPal keyboard, you can see numbers on the top keys on one of the settings. Press that key for the number.I don't see a #s on main keyboard option.
On android this was available.
All the 3rd party keyboards do that. Its not as bad now though. I like using SwiftKey so much I don't mind an occasional freeze up. I have worse issues with the stock keyboard.For me too,the SwiftKey doesn't pop up sometimes at all. Have to relaunch the stock messages app for it to show. And relaunching something on Apple device to get it work doesn't suite me well. If I'd want that I'd gone back to android
I like Swiftkey but I encountered a problem when using it with Messages: No keyboard is showing! It is sporadic but enough to discourage me from using it.
