The latest system is ios8. The following is a review of previous systems:

iOS 1 Keywords: The birth of iPhone

Perhaps looking at it now, at that time The scene is hard to imagine. When the first-generation iPhone was officially released, it was actually far behind its competitors at the time in some functions and aspects. In 2007, whether it was Windows Mobile, Palm OS, Symbian or even BlackBerry, they all had very powerful smart features at that time. In contrast, the first-generation iPhone does not support 3G networks, multitasking, third-party applications, copying and pasting text, adding attachments to emails, MMS messages, and new email reminders. , does not support changing the desktop background, does not support data sharing, does not support office document editing, does not support voice dialing, completely closes and hides system files... At that time, the iPhone was almost nothing special in everyone's eyes, but after several years Continuous improvement after the first upgrade: iOS 1.1.1 added the functions of TV output and double-clicking the Home button to customize operations. Later, double-clicking the Home button became a shortcut to activate the multitasking mode of the iOS system. The iOS 1.1.3 update mainly adds the functions of adjusting the order of home screen icons and adding web page shortcuts to the desktop. Apple calls this feature "Web Clips", which also reminds people that the iPhone at that time did not support the installation of applications.

iOS 2 Keywords: Apps

The second generation of iOS system came out in July 2008. Apple finally launched the App Store application store dedicated to iOS system. At that time, installing applications directly on smartphones seemed out of reach, but with the release of iOS 2, users could select and install third-party applications directly on their phones without connecting to a computer.

App Store

The emergence of the App Store can be said to be one of the most important changes to the iOS system. iPhone users can not only browse and install applications on their phones, but also perform version updates directly on their phones. This is a very big change and completely different from the way other systems download applications mainly through the Internet or third-party app stores. At the same time, Apple has also established an entirely own ecosystem based on the App Store. Whether it is applications, music or movies, users can directly enter credit card information on their mobile phones to make paid purchases. The entire purchase process has become extremely simple and convenient, which also promotes consumers' enthusiasm for paying purchases.

iOS SDK

The second major update brought by the iOS 2 system is the birth of the iOS SDK development tool kit. This is the first powerful development tool provided by Apple for iOS platform developers. And through this development tool, even 3D games have become extremely simple. iOS app development has since become more functional, better-looking, and more advanced than on other platforms. It was from this moment on that the powerful momentum of iOS platform applications began.

However, with the launch of the App Store, Apple is not only accompanied by the joy of success. In the process, Apple has also become the target of criticism from many users and competitors for not allowing users to install applications from channels other than the App Store. At the same time, the frequent appearance of pornographic and violent applications in the App Store has also put the App Store's review system under test again and again.

In the iOS 2 system, the support for the Microsoft Exchange mail service system and the addition of the MobileMe cloud service synchronization function also made the iOS 2 system at that time seem to be more than one stage ahead of all opponents. Later, in minor updates such as iOS 2.0.1 and iOS 2.0.2, Apple made timely corrections to bugs and errors such as battery issues.

iOS 3 Keywords: New features

iOS 3.0 came out in June 2009 with the iPhone 3GS. Like the 3GS, this version of the system does not have any major features.

On the contrary, Apple has filled various gaps in the system through iOS 3 with a large number of function and application upgrades.

Cut, copy and paste

Apple has brought a new text selection method in iOS 3. Their combination of text magnifier and selection slider is very intuitive and outperforms the competition in terms of practicality.

Spotlight Search

Finding content in iOS is very laborious, so a system-level search is imperative. Spotlight has added a search page to the left side of the home screen, where users can search for a variety of information, including contacts, emails, calendars, notes, and more. Apple has thus finally caught up with a feature already ubiquitous in BlackBerry, Palm OS, webOS and Windows Mobile: the ability to quickly enter text to search on the home screen.

Third-party application push notifications

Apple’s promise at the iOS 2 conference was not fulfilled until iOS 3. However, iOS push notifications are still far ahead of the competition. Notification push functions are somewhat similar to those originally brought about by multitasking, but if the push window pops up too frequently, it may make users feel unhappy.

In addition, MMS support and voice playback have also been added in iOS 3.

iOS 3.2 Keywords: iPad

The main purpose of iOS 3.2 is to add the necessary changes to the system to match the iPad screen resolution, including landscape home screens, new pop-up conversations, etc. .

Large screen UI example

In order to bring iOS to the iPad, Apple did not simply enlarge the iPhone UI, but added some changes specifically designed for the large screen. The most obvious one is the addition of the left-hand sidebar. Generally speaking, an application has a list of content to choose from, and the user will enter the content view after selecting it. In iOS 3.2, Apple placed the content list on the left side of the screen, and the content was displayed directly on the right side of the list, thus eliminating the need to return. After the iPad enters portrait mode, the content will be displayed in full-screen mode, and the content list is not hidden behind the return button, but appears in a pop-up form.

New app design

The iOS app has also received many iPad-specific changes. Safari has a separate bookmark bar, the App Store has added the CoverFlow effect, the Photos app will organize pictures in a stacked manner, the Music app has been simplified, and the Settings app has also gained a new dual-panel display. Most importantly, these native apps don't look like they've simply been "scaled up" onto the iPad's 1024x768 resolution display, but have been adjusted more naturally.

skeuomorphism

This UI style that is familiar to the majority of iOS users was added in iOS 3.2. Skeuomorphism adds an interface style that imitates real things to many native applications. Although many people think that this appearance looks a bit old, the bigger problem is that there is no direct connection between this realistic style and the user interface. An address book may look like a book, but the pages cannot be turned.

iOS 4 Keywords: Multitasking

iOS 4 came out in June 2010. Its main task is to bring more functions to advanced users, including multitasking and application files. folders, WiFi tethering, spell check, custom Spotlight search (web and Wikipedia), unified inbox, and support for multiple Exchange accounts.

Of course, multitasking is the biggest selling point of this version of the system. However, iOS 4 does not technically support true multitasking, which means it does not allow any application to run in the background.

In addition to multitasking, iOS 4 also brings some other innovative features:

FaceTime

In order to take advantage of the iPhone 4’s front camera, Apple brings Here comes the FaceTime video calling feature. Although they are not the first manufacturer to bring video calling, FaceTime is better than other similar functions and the interface is simpler.

Folders

In iOS 4, Apple finally brought the ability to create folders to the home screen. Their solution is as simple as dragging one app icon onto another to form a folder. This UI innovation was subsequently followed by Android 4.0.

Retina display

iPhone 4 has a faster processor and Retina display, allowing developers to create higher-quality applications. Since the resolution of the Retina display is exactly double that of the previous iPhone, developers do not have to rush to support this new screen.

Productivity features

Although iOS 4 may still not be able to attract hardcore BlackBerry users, Apple has at least gradually enriched the system through a series of feature additions, such as for multiple Exchange accounts support, and unify your inbox. System-level spell checking also appears for the first time, the Calendar app also allows users to hide individual items, and the Messages app also gains search capabilities.

iOS 5 Keywords: Siri, Notification Center and more

Like iOS 3, iOS 5 comes out with another iPhone with "S"; Likewise, iOS 5 contains a large number of new features. If Apple's hardware is the anvil in today's smartphone war, then iOS 5 is the hammer they use to carve out market share.

Siri

This "virtual assistant" replaces voice control in iOS and brings some very interesting functional experiences. Siri allows users to ask questions and then make suggestions in natural language. Siri can communicate with everything in the system and also supports text transcription. But as a beta feature, Siri also has some imperfections: it sometimes fails to connect to the network to perform speech recognition or transcription, and sometimes the feedback results are very strange.

Notification Center

This feature works similarly to Android. Users can swipe down from the top of the screen to view unread notifications received by the system, or through the small " ×" to clear the notification.

iMessage

With iOS 5, Apple began to seize the revenue of operators, and at the same time poached users for BlackBerry's BBM service. Similar to BBM, iMessage can display delivery receipts and send multimedia messages. Unlike the operator's SMS service, this feature is completely free. iMessage can automatically synchronize information between all users' iOS devices, but it is also limited to iOS users for communication.

No PC activation required

In iOS 5, Apple has removed the restriction that devices must be connected to a PC for activation, which undoubtedly brings great convenience to users.

iTunes Wi-Fi synchronization

The Wi-Fi synchronization function will only be performed while charging by default, and its working effect is also very good.

OTA upgrade

It is hard to believe that it was not until iOS 5 that Apple introduced the OTA upgrade function, and the system upgrade of iOS devices was truly separated from the PC.

iCloud

Finally, iOS 5 brings a new cloud service called iCloud that replaces MobileMe. With the help of this feature, iOS devices, as well as the documents and other files in them, can be backed up directly to iCloud. Among Apple's several attempts at cloud services, iCloud is undoubtedly the most successful.

iOS 6 Keywords: Goodbye, Google Maps

iOS 6 was released at WWDC in June 2012. This new version contains some surprises and expected changes, and Among them, the one that caused the biggest reaction was the addition of the map application.

Map

Google Maps has always been considered the benchmark for online maps. Since the first generation iPhone in 2007, it has also been the map service on the iPhone. However, due to the patent lawsuit between the two companies, Apple worked hard to develop its own map service.

But when it first came out, the quality of Apple Maps was full of errors and became the object of ridicule. Even CEO Cook issued a statement of apology.

Siri Enhancements

In the new version of Siri, the functions of this voice assistant have been further enhanced. Users can now use it to check sports scores, event schedules, player data, and restaurant reviews.

Notification Center

The new Do Not Disturb mode has been added to the notification function, through which users can set a period of time when they do not want to be disturbed by notifications. In addition, users can also quickly update status in the drop-down notification menu.

Passbook

In this Apple mobile payment solution, users can centralize relevant payment information, such as tickets, boarding passes and coupons. In the future, Apple may bring real mobile payment capabilities to Passbook, thereby directly competing with Google Wallet.

iOS 7 Keywords: Hello, Jony Ive

iOS 7 brings a new look to this already somewhat old operating system. In addition to the youthful color matching and UI, this system also contains many changes.

Appearance

iOS 7 was developed under the leadership of Jony Ive. He boldly abandoned the style of the Steve Jobs era and brought major visual changes to the system. Gone are the skeuomorphic, textured, and shiny icons, and the overall style of iOS 7 is more modern and flatter.

Control Center

Another example of learning from Android. Users no longer have to enter the settings application to adjust the device's functions. Now they only need to swipe up from the bottom of the screen, and the pulled-out control center contains many shortcut switches, such as volume/brightness adjustment, Wi-Fi/Bluetooth/ Do not disturb mode switch.

AirDrop

This feature allows users to easily share pictures, videos and other files with people around them. Although this feature is launching on OS X Mountain Lion, you can't share files across iOS and OS X.

iTunes Radio

This music streaming service is Apple’s attempt to challenge Spotify and Rdio. It allows users to select songs based on their needs, but the service is more about music stations centered around songs, artists, albums and genres.

Camera and Pictures

The new camera application is no longer as "foolish" as before. Users can adjust some shooting parameters and use built-in filters. The picture application has also added a sorting function for events or locations, allowing users to organize the photos they have taken more intuitively.

Multi-tasking

This feature has been significantly upgraded in iOS 7. After double-clicking the Home button, the system will open a new multi-tasking interface, which will display the icon and thumbnail of each open application. The way to close the application is also simpler, just click on the thumbnail of the application and slide up. .

Touch ID

The introduction of the iPhone 5S biometric sensor marks the arrival of a new security measure. Touch ID allows users to unlock their devices with their fingerprints or replace their Apple ID password when purchasing content, thus saving users time to a certain extent.
