What do you want to do with that number? I can think of a few ways to grab that value, but they are specific to different situations.

Do a calculation and set a UISlider's value to that number.

Are the inputting the number via a textfield?

Yes.

You can just use


[textField.text integerValue]


to grab the numeral value of the field. No need to pass it to a string.
