Efficiently Singularize and Pluralize Strings
InflectorKit ports the string inflection functionality of Rails ActiveSupport to Foundation.
InflectorKit joins FormatterKit & TransformerKit in providing well-designed APIs for manipulating user-facing content.
#import "NSString+InflectorKit.h"
for (NSString *singular in @[@"person", @"tomato", @"matrix", @"octopus", @"fish"]) {
NSLog(@"%@: %@", singular, [singular pluralizedString]);
}person: people
tomato: tomatoes
matrix: matrices
octopus: octopi
fish: fish
You can also add pluralization rules, including irregular and uncountable words:
#import "TTTStringInflector.h"
TTTStringInflector *inflector = [TTTStringInflector defaultInflector];
[inflector addPluralRule:@"^i(Pod|Pad)( Mini)?$" withReplacement:@"i$1s$2"];
[inflector addIrregularWithSingular:@"lol" plural:@"lolz"];
[inflector addUncountable:@"Herokai"];
for (NSString *singular in @[@"iPad Mini", @"lol", @"Herokai"]) {
NSLog(@"%@: %@", singular, [singular pluralizedString]);
}iPad Mini: iPads Mini
lol: lolz
Herokai: Herokai
