<lang objc>@interface NSString (StripCharacters)

- (NSString *) stripCharactersInSet: (NSCharacterSet *) chars;

@end

@implementation NSString (StripCharacters)

- (NSString *) stripCharactersInSet: (NSCharacterSet *) chars {

return [[self componentsSeparatedByCharactersInSet:chars] componentsJoinedByString:@""];

}

@end</lang>

To use:

<lang objc> NSString *aString = @"She was a soul stripper. She took my heart!";

NSCharacterSet* chars = [NSCharacterSet characterSetWithCharactersInString:@"aei"];

// Display the NSString.

NSLog(@"%@", [aString stripCharactersInSet:chars]);</lang>
