Apple Productivity Apps, formerly and commonly known as iWork, is an office suite of applications created by Apple Inc. for its OS X and iOS operating systems, and also available cross-platform through the iCloud website. It includes Keynote, a presentation program; the word processing and desktop publishing application Pages;〔 and the spreadsheet application Numbers.〔 It is generally viewed as a prosumer office suite targeted at home and small business users, with fewer features than competitors such as Microsoft's Office for Mac and the open source LibreOffice project (and indeed its own earlier versions〔http://arstechnica.com/apple/2013/11/review-the-productivity-suite-formerly-known-as-iwork/〕), but has a simpler user interface, strong touchscreen support and built-in links with Apple's iCloud document-hosting service and its Aperture and iPhoto image management applications. Apple's design goals in creating iWork have been to allow Mac users to easily create attractive documents and spreadsheets, making use of OS X's extensive font library, integrated spelling checker, sophisticated graphics APIs and its AppleScript automation framework. The equivalent Microsoft Office applications to Pages, Numbers, and Keynote are Word, Excel, and PowerPoint, respectively. Although Microsoft Office applications cannot open iWork documents, iWork applications can export documents from their native formats (.pages, .numbers, .key) to Microsoft Office formats (.doc, .xls, .ppt, etc.) as well as to PDF files. The oldest application in iWork is Keynote, first released as a standalone application in 2003. Pages was released with the first iWork release in 2005; Numbers was added in 2007 with the release of iWork '08. The next release, iWork '09, also included access to iWork.com, a beta service that allowed users to upload and share documents,〔 now integrated into Apple's iCloud service. An iOS port was released in 2010 with the first iPad and has been regularly updated since. In 2013, Apple released a new OS X version and iWork for iCloud, a set of cross-platform web applications replicating the native software versions. iWork was initially sold as a suite for $79, then later at $19.99 per app on OS X and $9.99 per app on iOS. Apple announced on October 22, 2013 that iOS devices purchased from September 2013 onward and OS X computers purchased from October 2013 onward, whether new or refurbished, are eligible for a free download of all three iWork apps. iWork for iCloud, which also incorporates a document hosting service, is free to all holders of an iCloud account. ==History== The first version of iWork, iWork '05, was announced on January 11, 2005 at the Macworld Conference & Expo and made available on January 22 in the United States and worldwide on January 29. iWork '05 comprised two applications: Keynote 2, a presentation creation program, and Pages, a word processor. iWork '05 was sold for US$79. A 30-day trial was also made available for download on Apple's website.〔 Originally IGG Software held the rights to the name ''iWork''.〔(【引用サイトリンク】 url = http://daringfireball.net/2005/01/iwork )〕 While iWork was billed by Apple as "a successor to AppleWorks",〔 it does not replicate AppleWorks's database and drawing tools. However, iWork integrates with existing applications from Apple's iLife suite through the Media Browser, which allows users to drag and drop music from iTunes, movies from iMovie, and photos from iPhoto and Aperture directly into iWork documents.〔 iWork '06 was released on January 10, 2006 and contained updated versions of both Keynote and Pages. Both programs were released as universal binaries for the first time, allowing them to run natively on both PowerPC processors and the Intel processors used in the new iMac desktop computers and MacBook Pro notebooks which had been announced on the same day as the new iWork suite. The next version of the suite, iWork '08, was announced and released on August 7, 2007 at a special media event at Apple's campus in Cupertino, California. iWork '08, like previous updates, contained updated versions of Keynote and Pages. A new spreadsheet application, Numbers, was also introduced. Numbers differed from other spreadsheet applications, including Microsoft Excel, in that it allowed users to create documents containing multiple spreadsheets on a flexible canvas using a number of built-in templates. iWork '09, was announced on January 6, 2009 and released the same day. It contains updated versions of all three applications in the suite. iWork '09 also included access to a beta version of the iWork.com service, which allowed users to share documents online until that service was decommissioned at the end of July 2012. Users of iWork '09 could upload a document directly from Pages, Keynote, or Numbers and invite others to view it online. Viewers could write notes and comments in the document, and download a copy in iWork, Microsoft Office, or PDF formats. iWork '09 was also released with the Mac App Store on January 6, 2011 at $19.99 per application, and received regular updates after this point, including links to iCloud and a high-DPI version designed to match Apple's MacBook Pro with Retina Display. On January 27, 2010, Apple announced iWork for iPad, to available as three separate $9.99 applications from the App Store. This version has also received regular updates including a version for pocket iPhone and iPod touch devices, and an update to take advantage of Retina Display devices and the larger screens of recent iPhones. On October 22, 2013, Apple announced an overhaul of the iWork software for both the Mac and iOS. Both suites were made available via the respective App Stores. The update is free for current iWork owners 〔 and was also made available free of charge for anyone purchasing an OS X or iOS device after October 1, 2013.〔(【引用サイトリンク】url=https://www.apple.com/creativity-apps/mac/ )〕 Any user activating the newly free iWork apps on a qualifying device can download the same apps on another iOS or OS X device logged into the same App Store account. The new OS X versions have been criticized for losing features such as multiple selection, linked text boxes, bookmarks, 2-up page views, mail merge, searchable comments, ability to read/export RTF files, default zoom and page count, integration with AppleScript. Apple has provided a road-map for feature re-introduction, stating that it hopes to reintroduce some missing features within the next six months. As of April 1, 2014 a few features--e.g., the ability to set the default zoom--had been reintroduced, though scores had not. In October 2014, writer John Gruber commented on the numerous font handling problems that "it's like we're back in 1990 again."〔(【引用サイトリンク】url=http://support.apple.com/kb/HT6049?viewlocale=en_GB&locale=en_GB )〕 Due to using a completely new file format that can work across OS X, Windows, and in most web browsers by using the online iCloud web apps, means the current version of iWork (iWork 13) does not open or allow editing of documents created in versions prior to iWork 09, with users who attempt to open older iWork files being given a pop-up in the new iWork 13 app versions telling them to use the previous iWork 09 (which users may or may not have on their machine) in order to open and edit such files. Accordingly, the current version for OS X (which was initially only compatible with OS X Mavericks 10.9 onwards, and now only compatible with OS X Yosemite 10.10) moves any previously installed iWork 09 apps to an iWork 09 folder on the users machine (in /Applications/iWork '09/), as a work-around to allow users continued use of the earlier suite in order to open and edit older iWork documents locally on their machine.抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「IWork」の詳細全文を読む スポンサード リンク
