Question

I work on the app with some calculate function. I have a UITextField where user enter a number and UILabel where is result. How can I display some text in second UILabel depending on the number in the first UILabel?

Example:

If number in *firstLabel less than 20, then display in *secondLabel: small

If number in *firstLabel from 20 to 30, then display in *secondLabel: normal

If number in *firstLabel greater than 40, then display in *secondLabel: big

I hope you understood what i mean. Thank you! Sorry for my english.

Answer 1

you need to get the int value from your firstLabel, Which is stored as text, you could get it by using NSString intValue function.

Use the below

int intValueFromFirstLabel = [firstLabel.text intValue];

if(intValueFromFirstLabel < 20)
{
  secondLabel.text = @"small";
}
else if(intValueFromFirstLabel >= 20 && intValueFromFirstLabel <= 30)
{
  secondLabel.text = @"normal";
}
else if(intValueFromFirstLabel > 40)
{
  secondLabel.text = @"big";
}
