Parse, validate, manipulate, and formatte dates easily in Objective-C (API inspired by moment.js)

YLMoment

YLMoment is a library which provides an high abstraction level for parsing, validating, manipulating, and formatting the dates in Objective-C.

Its API is inspired by the well known moment.js library, however unlike its father, its core is built upon the Foundation Framework components (NSDate, NSDateFormatter,etc.) for a full interoperability with iOS.

Installation

Manually

Copy the YLMoment folder into your project and then simply import the "YLMoment" in the file(s) you would like to use it in.

CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like YLMoment in your projects.

Podfile

platform :ios, ‘5.0’
pod "YLMoment", "~> 0.1.0"

Usage

Formatting dates

YLMoment *moment = [YLMoment now];

NSLog(@"%@", [moment format:@"MMMM dd yyyy, h:mm:ss a"]); // October 27 2013, 10:49:48 AM
NSLog(@"%@", [moment format:@"MMM dd yy"]);               // Oct 27 13
NSLog(@"%@", [moment format:@"yyyy 'escaped' yyyy"]);     // 2013 escaped 2013
NSLog(@"%@", [moment format]);                            // 2013-10-27T10:49:48+0100

Relative Times

YLMoment *moment1 = [YLMoment momentWithDateAsString:@"20111031"];
NSLog(@"%@", [moment1 fromNow]); // 2 years ago

YLMoment *moment2 = [YLMoment momentWithDateAsString:@"2012/06/20" format:@"yyyy/MM/dd"];
NSLog(@"%@", [moment2 fromNow]); // a year ago

NSLog(@"%@", [[[YLMoment now] startOf:@"day"] fromNow]);  // 19 hours ago
NSLog(@"%@", [[[YLMoment now] endOf:@"day"] fromNow]);    // in 5 hours
NSLog(@"%@", [[[YLMoment now] startOf:@"hour"] fromNow]); // 11 minutes ago

Languages

YLMoment *french = [[YLMoment now] addAmountOfTime:-3 forUnitKey:@"s"];
[french setLocale:[NSLocale localeWithLocaleIdentifier:@"fr_FR"]];
NSLog(@"%@", [french fromNow]); // il y a quelques secondes
    
YLMoment *albanian = [[YLMoment now] addAmountOfTime:-3 forUnitKey:@"s"];
[albanian setLocale:[NSLocale localeWithLocaleIdentifier:@"sq_AL"]];
NSLog(@"%@", [albanian fromNow]); // disa sekonda me parë
    
YLMoment *spanish = [[YLMoment now] addAmountOfTime:-3 forUnitKey:@"s"];
[spanish setLocale:[NSLocale localeWithLocaleIdentifier:@"es_ES"]];
NSLog(@"%@", [spanish fromNow]); // hace unos segundos
    
YLMoment *reference = [YLMoment momentWithArray:@[@2013]];
YLMoment *english   = [[YLMoment now] addAmountOfTime:-3 forUnitKey:@"s"];
[english setLocale:[NSLocale localeWithLocaleIdentifier:@"en_US"]];
NSLog(@"%@", [english fromMoment:reference]); // in 11 months
