Getting an Int from a UITextField and Limiting UITextField to Ints
<p>I'm very new to iPhone programming, but am trying to delve into it. </p>

<p>I have an interface setup in interface builder. I am trying to have the user input numbers, in which I will use to calculate a value.</p>

<p>Thus, I have two UITextFields. What I want to do is to access these numbers (ints) that the user inputs. How do I go about doing this? is it simply blah.text (blah being my UITextField). Also, is there a way to only allow a user to input ints into the UITextField? Sorry if these questions sound so elementary.</p>

<p>Thanks.</p>
