You’re not giving me much information in your question. How do the other buttons work?
If I was making a calculator I would have a label at the top showing the current reading. On press of a number button I would update the label with the number at the end.
For a decimal button you just add a . to the end of the label. You might want to have a global variable
BOOL hasDecimalPlaceand set it to true so you know if there is already a decimal place. Just remember to set it to false again when you clear the view or do a calculation or similar.
