NSNumber from a NSString

[mkenney]

Another dumb question from me. I can't seem to find a way to easily convert a NSString to a NSNumber. I know I'm making this harder then it needs to be!!

UITextField *aText;
NSNumber *aNum;

aNum= ??????? [aText text];

The textField will have a number in it representing a dollar and cents amount...

Thanks again for all your help!!

There doesn't seem to be any way of converting directly, but NSString has a number of value methods (doubleValue, floatValue, intValue, integerValue, longLongValue, boolValue) which you can use as an intermediate stage eg.

NSNumber  *aNum = [NSNumber numberWithInteger: [[aText text] integerValue]];

I think I might have to use NSNumberFormatter???

If the text field contains anything other than digits and a decimal point, yes. If the number is just a dollar value then you can use -floatValue on the string. You may also like to look at NSScanner.
