Sometimes, it’s the simple things which can be the most handy. Here’s a quick category on NSString to allow all characters within a set ([cc lang=”objc” inline=”true” width=”0″ theme=”geshi”]NSCharacterSet *illegalCharacterSet[/cc] or [cc lang=”objc” inline=”true” width=”0″ theme=”geshi”]NSCharacterSet *symbolCharacterSet[/cc], say) to be easily and efficiently removed. This fills a gap in between the [cc lang=”objc” inline=”true” width=”0″ theme=”geshi”]stringByTrimmingCharactersInSet:[/cc] and [cc lang=”objc” inline=”true” width=”0″ theme=”geshi”]stringByReplacingCharactersInRange: withString:[/cc] & [cc lang=”objc” inline=”true” width=”0″ theme=”geshi”]stringByReplacingOccurrencesOfString: withString:[/cc] methods, which only act upon the ends of the receiver or require a continuous range or fixed string respectively.
