Use intValue or integerValue from the NSString class.

int answer = [myTextField.text intValue];

or

NSInteger answer = [myTextField.text integerValue];

You can also use floatValue and doubleValue for floating-point inputs.

NSInteger is not a class; no "*" needed, and I don't think "int" is a method on NSString. – Jesse Rusak Jun 26 '12 at 00:28
Check http://developer.apple.com/library/ios/#documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html for intValue. Returns the integer value of the receiver’s text. - (int)intValue – daihovey Jun 26 '12 at 00:32
"intValue" is a method on NSString; "int", which is what your answer says, is not. – Jesse Rusak Jun 26 '12 at 00:34
aha, yes well spotted :) – daihovey Jun 26 '12 at 00:36
