彻底颠覆

    自从蒂姆•库克让伦敦人乔尼•伊夫执掌iOS大权后，外界纷纷猜测这位工业设计领域的大牛会带来哪些变化。毕竟，iOS设备的出货量已超过6亿部，而应用程序下载量更高达500亿次，iOS已成为最为活跃的手机生态系统。

    现在真相大白，就像库克所说的，iOS 7是苹果有史以来最重大的软件升级。从焕然一新的人机设计，再到重新设计多任务系统，iOS 7的变化可谓数不胜数。对于熟悉伊夫，或者是了解苹果公司（Apple）内幕的人而言，iOS 7的变化多少在意料之中。据报道，伊夫本人并不是“拟物化”的追随者，这种设计强调将现实世界的某些元素融入到数字应用中，例如苹果之前的播客应用，它的界面就是一部老式收音机。在iPhone诞生6年后，无数用户早对iOS烂熟于心，所谓视觉提示已经没有必要。

    iOS 7即将在今年秋天登场，下面就是它最令人瞩目的11项新功能。

扁平化的iOS

    随着iOS 7第三季度正式推出，用户将很快发现自己熟悉的界面已不复存在。整个系统更扁平化、更醒目，也变得更透明。在大部分场景下，应用图标和文字看起来都像是纯粹的二维图形，整个屏幕的配色也更加鲜艳。半透明化的菜单频频出现，新的控制中心就是其中一个例子，iOS 7看起来颇有嬉皮士风范。

Radically new

    When Tim Cook placed Jony Ive in charge of iOS development, many speculated about what changes the esteemed London-born industrial designer would bring. After all, with over 600 million iOS devices sold and 50 billion apps downloaded, iOS is a thriving software ecosystem in its own right.

    Now we know: iOS7 represents, according to Cook, the biggest software update ever. From a different aesthetic to a new multitasking system, the changes are many. That Ive and team went in a different direction with iOS7's looks should come as little surprise to those who know Ive or follow Apple (AAPL, Fortune 500) closely. Ive was reportedly not a fan of "skeuomorphism," the design philosophy that led to digital representations of real-world items, like the reel-to-reel tape deck previously found in Apple's podcast app. After six years, most users should be pretty familiar with how iOS works without such visual cues.

    Here's a look at many of the new features users will discover this fall.

iOS, but flatter

    When iOS7 becomes widely available this fall, users will quickly notice that any sort of nostalgic visual cues have been done away with. This operating system is flatter, bolder, and more translucent. For the most part, app and text look more two-dimensional, and a more striking color palette permeates every screen. Semi-transparent menu layers, like those seen in the new Control Center, lend an updated, hipper look.

真正的多任务

    多任务，或者说让多个应用程序同时运行，这无疑是苹果极为看重的一点。应用间的切换非常迅速，但美中不足的是，基于节电的考虑，苹果禁止了大部分第三方应用在后台更新数据。多任务界面也进行了重新设计，图标变得更大了，用户可以更方便地在应用之间进行切换。

Real multitasking

    Multitasking for iOS users, or the ability to have several apps running at once, was a distinctly Apple experience. Switching from app to app was quick, but many third-party apps couldn't update with new information in the background, something Apple mostly disallowed in favor of battery life. A new multitasking screen treats many open apps as larger panes to swipe through.

更智能的Siri

    苹果的个人数字助手Siri给大家带来完全不同的体验。全新打造的用户界面不必多说，可以同时使用男女两种语音也符合人们的期待。更重要的是，苹果还承诺将提升Siri的应答速度、答案来源也将更多元化。新的Siri更可以完成回电话、播放语音邮件，或者控制iTunes Radio等复杂功能。

续航时间更长

    和OSX小牛一样，iOS 7也进行了彻底改造，以实现终极节电。例如，应用程序能利用新的多任务系统判断用户的无线或WiFi信号是否良好。如果信号够好，应用程序就能获取数据——这将消耗电能，如果信号不够好，它们就继续等待。（在信号不好的情况下获取数据会消耗更多电。——译注）

A way better Siri

    You'll notice something different about Apple's spunky digital assistant, and we're not just talking about a new coat of paint, or the fact that Siri sounds more natural with an updated male or female voice. Apple promises faster answers to questions, more sources for Siri to dig through, and the ability to ask it to return calls, play voicemail, and control iTunes Radio.

Better battery life

    Just like OSX Mavericks, iOS7 was designed from the ground up to conserve battery life where possible. As just one example, the new multitasking ability helps apps figure out whether or not users have a good mobile or WiFi Internet connection. Depending on signal strength, apps will fetch data -- drawing energy from the battery in the process -- or hold off.

任务控制

    全新的控制中心内置了许多新按钮，例如调节屏幕亮度、WiFi开关、蓝牙开关、更换音乐等、用户还能在这里访问摄像头、日历、时钟和手电筒。

Mission control

    The new Control Center offers users many of the virtual buttons required to adjust screen brightness, turn WiFi and Bluetooth on and off, change music tracks, and access shortcuts to their camera, calculator, timer, and flashlight.

更智能的通知系统

    对于成天使用iPhone的人而言，通知信息可谓不胜其烦。新的通知中心基本能让你满意，而且它还能按类别划分通知。iOS 7新加入了“今天”选项，能在一页屏幕上显示出今天的天气、约会、未接电话等各类信息。

Smarter notifications

    For those who use their iPhones for work and play -- and let's face it, there are more and more of them -- the new Notifications Center covers the basics but also organizes that information into more useful sections. A new feature called "Today" serves up a summary of today's weather, appointments, missed calls, and other information in one screen.

摄像头加入多重滤镜

    标准、全景和视频功能依然是标配，但新的iOS 7提供了“square”高光拍照模式和至少9种滤镜。这些滤镜能实现黑白、低对比度和怀旧复古等效果。

One camera, many filters

    The Camera app still offers the ability to shoot standard stills, panoramas, and videos, but now there's a "square"-shaped photo feature and at least nine built-in filters that render shots in black and white, cool down the contrast, or dial up the sepia for a vintage-retro look.

改进的图片应用

    iOS用户终于不用在一大堆图片间不停滚动，苦苦寻找想要的东西了。基于时间和拍摄地点等因素，苹果能将图片按“时刻”或“事件”排列，并组织到“集合”或相册中，然后按照“年份”显示出来。（虽然说起来很拗口，但实际非常简单。）

Improved photos

    iOS users don't have to scroll through countless photos to get at what they want anymore. Based on factors like time and place, Apple can organize shots into what it calls "moments," or events, that are housed in "collections," or albums, that show up under "years." (It's a lot simpler than it sounds. Trust us.)

分享

    AirDrop文如其意，能提供WiFi和蓝牙数据传输。用户能便捷安全地与周围朋友分享照片、视频、联系人名单等。甚至应用程序中的数据也能通过“分享”按钮进行分享。

Dropping off

    AirDrop for iOS works as you might expect, provided there's WiFi and Bluetooth around. Nearby users can quickly -- and securely -- share photos, videos, contacts, and anything else by pressing the "Share" button in an app.

更好的滑动

    iOS 7的Safari同样改动不小。新的扁平化按钮隐藏在屏幕下方，直到用户手指滑到附近才出现。如此一来，网页的可视面积更大了。新的标签页呈竖排排列，这和OSX小牛如出一辙，用户只要向下滑动就可轻松切换。

收音机

    风传已久的苹果流媒体音乐服务终于登场。它拥有数以百计的标准和自定义频道，用户可以在任何苹果设备（只要不算太旧）上收听音乐。iTunes Radio内置广告，意味着听众会经常听到商业信息，不过iTunes Match的用户可以享受到无广告版。（财富中文网）

Scroll master

    Safari for iOS has received some nips and tucks, namely new flat buttons that stay hidden until users scroll so they can see more of a web page at once. The Reading List follows the same philosophy to its OS X Mavericks counterpart: Going from one story to another means simply scrolling down.

Radio

    Apple's oft-rumored music streaming service has arrived. With hundreds of featured and user-customizable stations, listeners can jam on any contemporary Apple device. iTunes Radio is ad-supported, meaning most listeners will hear the occasional commercial, but iTunes Match subscribers will experience their streamed music ad-free.
