Is it possible to restrict the amount of characters the user is able to type?
I only want them to be able to type 30 characters at most. [import]uid: 8697 topic_id: 31228 reply_id: 331228[/import]
You can during the editing phase of the textfield handler test the length of the string and if it’s too long, chop it at your desired length. [import]uid: 19626 topic_id: 31228 reply_id: 124908[/import]
During the “editing” event.phase you can check to see the length of the string and when it hits the limit+1 chop off the last character.
In the docs they say event.oldText shows what was there before the current character was typed, but that seems to be missing in real-world use. If they get that fixed/back in, no chopping would be needed, just replace the text with event.oldText when the max length was reached.

I also had same problem and using of event.oldText is works fine, thanks for the idea. But there is a some new problem: after “textBox.text = event.oldText” command,
the cursor is set to startPosition =1 in the textBox (the beginning of the text in the textBox) . It is expected that the cursor will remain at the end of the text.
How can I fix it? [import]uid: 172733 topic_id: 31228 reply_id: 126105[/import]
Wow, that looks like a bad problem because I don’t see anywhere in the docs where you can set the cursor position in a TextField.
But, the docs seem to be spread over hundreds of acres, so it’s possible I’ve missed it.
Maybe someone from CL will stop by and give the definitive word…

The following works for me on iOS devices.
if ( “editing” == event.phase ) then
if string.len(lastNameFieldNative.text) > 30 then
lastNameFieldNative.text = lastNameFieldNative.text:sub(1,30)
end
end
