Whoops. Forgot to mention that I am not using WO 4.0. I'm a little behind the times (WO 3.1). Thanks again, Joshua
I have an NSString object that I would like to test to make sure that it contains only numeric characters and no alpha characters. The test will happen almost everytime the user makes a request to the app, so I am trying to decide which is the tightest, quickest, most effiecient method to use. Should I convert the string into an NSNumber or NSArray or NSScanner class and what is the "best" method within one of these three classes to use? Thanks, Joshua
