How to convert an NSString into an NSNumber

Question

How can I convert a NSString containing a number of any primitive data type (e.g. int, float, char, unsigned int

Answer 1

You can use -[NSString integerValue], -[NSString floatValue], etc. However, the correct (locale-sensitive, etc.) way to do this is to use -[NSNumberFormatter numberFromString:] which will give you an NSNumber converted from the appropriate locale and given the settings of the NSNumberFormatter (including whether it will allow floating point values).
