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 counterpart, its core is built upon the
Foundation Framework components (
NSCalendar, etc.) to enable the interoperability with them.
This library is designed to facilitate the manipulation of times, dates, calendars, and durations in Objective-C by providing a single, easy, and unified approach to dealing with them.
If you want have a quick overview of the project take a look to this blog post.
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
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
// Uses my current time zone: here the CET time (GMT+1) YLMoment *now = [YLMoment now]; NSLog(@"%@", [now format]); // 2014-01-18T18:51:10+0100 // Change the time zone of the moment now.timeZone = [NSTimeZone timeZoneWithName:@"GMT"]; NSLog(@"%@", [now format]); // 2014-01-18T17:51:10+0000 // Convenient way to use get the UTC time YLMoment *utc = [YLMoment utc]; NSLog(@"%@", [utc format]); // 2014-01-18T17:51:10+0000
YLMoment supports a lot of languages (see the list below) and is easy to use.
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] subtractAmountOfTime:3 forUnitKey:@"s"]; [spanish setLocale:[NSLocale localeWithLocaleIdentifier:@"es_ES"]]; NSLog(@"%@", [spanish fromNow]); // hace unos segundos YLMoment *reference = [YLMoment momentWithArray:@[@2013]]; YLMoment *english = [[YLMoment now] subtractAmountOfTime:3 forUnitKey:@"s"]; [english setLocale:[NSLocale localeWithLocaleIdentifier:@"en_US"]]; NSLog(@"%@", [english fromMoment:reference]); // in 11 months

All contribution is welcomed! ;)
The recommended approach to use YLMoment in your project is using the CocoaPods package manager, as it provides flexible dependency management and dead simple installation.
Install CocoaPods if not already available:
$ [sudo] gem install cocoapods $ pod setup
Go to the directory of your Xcode project, and Create and Edit your Podfile and add YLMoment:
$ cd /path/to/MyProject $ touch Podfile $ edit Podfile source 'https://github.com/CocoaPods/Specs.git' platform :ios, '5.0' # Or platform :osx, '10.8' pod 'YLMoment', '~> 0.9.1'
Install into your project:
$ pod install
Open your project in Xcode from the .xcworkspace file (not the usual project file)
$ open MyProject.xcworkspace
Download the project and copy the
YLMoment folder into your project and then simply
#import "YLMoment.h" in the file(s) you would like to use it in.
Contributions are welcomed and encouraged ♡.
