  • 0

I have a UITextField for which I get input from some buttons that are part of the UI (so the input does not come form the phone’s virtual keyboard). I want to limit that number of characters. I tried using the shouldChangeCharactersInRange, but it only works if the input comes form the virtual keyboard, and it doesn’t work if the input comes from the buttons on the UI. Is there anyway I can solve this without programmatically having to count the characters in the text field every time I want to update it?

Thank you,

    Since you are programmatically making changes to the UITextField once the user clicks the relevant buttons on the UI, you should keep track of the number of characters entered using a counter.
    Increase the value of the counter every time a relevant UI button is touched. Update the textfield only if the counter value is <= maximum allowed no. of characters.
