Accessing and manipulating Integer values from a textField

I playing around with fun concepts and was wondering how you handle numeric inputs into a text field. I set the keyboard type to "number pad" and created IBOutlets from each value. How would one go about getting the input and inserting it into a formula? Here's a couple screen shots as an example:

If you want to get the value of a text field, you simply access its "text" property

var textFromTextField = self.textField.text

EDIT: Just now realizing you're working in Objective-C

UITextField *textField = [[UITextField alloc] initWithFrame:self.someObj.frame];
textField.text = @"Here I am";

NSString *textFromTextField = textField.text;

You're just converting a text value to an integer and encapsulating that with an NSNumber in that line of code. It shouldn't be any more different getting a numeric value from a text field as it is getting an entire paragraph. It's all in string format.

EDIT: I see that you deleted your comment, so I'm assuming you understand now. Good luck!
