1iOS8测试版升级方法并不复杂&&&&WWDC2014中，苹果发布了最新的iOS8系统预览版，在很多功能方面进行了升级。不过正如去年的WWDC2013中刚刚发布iOS7预览版一样，目前的iOS8测试版同样存在着诸多问题，首先要说的是不建议大家升级，所以感兴趣的朋友还是在这里简单了解一下目前iOS8测试版的体验情况吧。iOS8&beta更新方法+体验&&&&和iOS7测试版更新时一样，普通用户升级到iOS8测试版也可以，并不需要开发者账号。升级过程也并不复杂，这里简单说明一下。&&&&首先在搜索引擎中搜索并iOS8&beta的系统包（很多论坛或中都有，注意下载正确对应的型号和运营商版本），留作后用。然后将手机与电脑连接，并打开，点击Shift按键同时点击“检查更新”，选择解压后的iOS8&beta包，此时便进入了更新当中，等待即可。按住Shift键盘的同时点击检查更新点击更新查找下载的安装包打开安装包提取更新&&&&需要注意的是，更新过程中或升级完成后都可能遇到未预料到的问题，笔者和笔者同事都遇到了不同的问题。所以提醒大家，如果真的把持不住想要升级iOS8测试版，那么一定要做好充分心理和行动准备，提前做好备份，并记住自己手机的IMEI码、序列号等信息。等待即可产品：
2iOS8测试版界面变动和输入操作iOS8测试版界面变动和输入操作界面：&&&&iOS8测试版在界面上的变化并不像发布前消息曝光的那样，没有新增的Healthbook、CarPlay独立应用图标等等，目前只能够看到Health（非“book”）和一个Bug&Reporter（开发者提交Bug相关应用，正式版可能会消失）。&&&&另外，iOS8中新增了一张静态，或许是为了迎合界面的扁平化风格，这张壁纸下部分的水纹被“磨平”了。主界面输入操作：&&&&苹果在WWDC2014中介绍了iOS8新增了Quicktype键盘，支持根据用户习惯等进行词汇联想、输入建议，当然，这在Android等的第三方输入键盘等都早已具备，键盘也一直以来是苹果iOS的不足之处。iOS8测试版英文输入已经能够具有预测输入建议，九宫格输入还没有明显优化，可以主要期待一下第三方键盘。键盘输入存在联想功能产品：
3iOS8通知中心可编辑/控制中心等小变化iOS8通知中心可编辑/控制中心等小变化通知中心：&&&&目前的通知中心已经取消了“全部”栏，只留有“今天”和“通知”，且下方添加了一个“编辑选项”，支持对通知内容进行自定义了，支持添加或删除插件，这点很不错。当然，并非所有插件都能够添加，目前主要能够显示的只有几个。通知中心留有“今天”和“通知”栏&显示插件可以编辑iOS7的通知中心/iOS8&beta控制中心控制中心：&&&&iOS8&beta上滑控制中心只新增了与Mac相同的功能，快捷选项仍然不能够自定义，这点有些遗憾。天气：&&&&目前的天气应用虽然界面风格与之前基本无异，不过左下角的合作商已经由原来的“YAHOO!”变成了“The&Weather&Channel”。从通知中心底部的信息也可以看出天气去除了YAHOO，只留有股票信息仍由YAHOO提供。天气信息合作商变化产品：
4iOS8相机及Spotlight搜索iOS8相机及Spotlight搜索相机：&&&&iOS8&beta对相机进行了升级，向开发者开放了API，第三方应用可以调取相机信息。目前的相机中显示的拍摄选项只是英文，没有翻译成中文，所以中国用户使用起来可能会不便。这主要因为是测试版尚不健全。&&&&目前拍照完毕后可以对照片进行比iOS7更多的编辑，包括亮度、色彩调整等，实际上是在原来滤镜基础上又一次整合了一些相机应用的后期功能。相机增加了更多编辑选项Spotlight搜索：&&&&目前的Spotlight搜索（在主界面下滑可以调出）关联了更多互联网内容，这可以在设置中自行调整。Spotlight搜索/右侧为应用商店的搜索中增加了更多常搜关键词推荐产品：
5iOS8的iMessage&整合&微信功能iOS8的iMessage&整合&功能iMessage信息：&&&&iOS8对iMessage进行了明显升级，目前可以支持语音输入、图片和视频输入，经测试，如果接受信息者没有升级到iOS8，也能够接收到来自iOS8的语音、图片或视频iMessage信息。当然，如大家所知，这一功能很像是微信，但操作当时不同，不像微信那样的平台化，以功能增加为主，也只限于苹果用户之间使用，所以目前应该不会对微信这类应用造成威胁。信息可以设置一段时间后自动删除/按住输入框左侧的相机图标可以发送视频可以发送图片或是音频等产品：
6iOS8锁屏快捷回复信息/多任务升级iOS8锁屏快捷回复信息/多任务升级快捷回复：&&&&iOS8中收到信息后，可以直接在锁屏界面回复信息（或标记已读），而不用再进入到应用当中回复，很方便；另外在也可以在通知中心中回复。iOS8可在锁屏通知中快捷回复消息也可在通知中心中回复多任务后台:&&&&双击Home键弹出的多任务后台上方会显示最近使用的联系人列表，填补了之前的空位，也便于通话操作。多任务后台上方显示最近联系人产品：
7iOS8的健康应用/可能遇到的BugiOS8的健康应用/可能遇到的BugHealth：&&&&苹果已经于很多医疗机构合作完善HealthKit体验，目前iOS8中存在一个独立的Health应用，可以看出信息非常全面（但还是英文状态），涉及到了心率监测等、甚至细化到了维生素的统计方面，很全面，不过实用性还有待验证，且如果更多的依赖医疗结构的话，在国内暂时并不容易普及。项目非常之多睡眠分析/输入个人信息一些Bug：&&&&除了之前提到过的中英文混乱等问题，iOS8&beta还存在一些其他问题，比如对有些第三方应用存在兼容性问题（常见的是不能够正常打开），的Touch&ID存在启动缓慢问题，功能的下拉选项（比如传照片时弹出的选择照片等选项）基本废掉，等等诸如此类。&&&&就目前的iOS8第一个测试版来说，还不建议普通用户马上升级，升级之后可能对正常使用造成很多影响。不过期待苹果尽快发布iOS8&beta2，并解决这些问题。当然，更完善的版本应该还是会在下一代（）发布时的正式版当中面世。

iOS8带来了很多人性化改善，不过目前iOS8 beta版尚存在一些Bug，可能对使用造成影响，暂时不建议升级。

iOS SDK Release Notes for iOS 8.0 Beta 2
Important:
This is a preliminary document for an API or technology in development. Apple is supplying this information to help you plan for the adoption of the technologies and programming interfaces described herein for use on Apple-branded products. This information is subject to change, and software implemented according to this document should be tested with final operating system software and final documentation. Newer versions of this document may be provided with future betas of the API or technology.
Introduction
Bug Reporting
Notes and Known Issues
Introduction
iOS SDK 8.0 provides support for developing iOS apps. It is packaged with a complete set of Xcode tools, compilers, and frameworks for creating apps for iOS and OS X. These tools include the Xcode IDE and the Instruments analysis tool, among many others.
With this software you can develop apps for iPhone, iPad, or iPod touch running iOS 8. You can also test your apps using the included iOS Simulator, which supports iOS 8. iOS SDK 8.0 requires a Mac computer running OS X v10.9.3 (Mavericks) or later.
This version of iOS is intended for installation only on devices registered with the Apple Developer Program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.
For more information and additional support resources, visit /programs/ios/.
Bug Reporting
To report any bugs not mentioned in the Notes and Known Issues section, use the Bug Reporter app or Bug Reporter on the Apple Developer website (/bugreporter/). You can quickly get to the Bug Reporter app from the Notifications Panel. Additionally, you may discuss these issues and iOS SDK 8.0 in the Apple Developer Forums: . To get more information about iCloud for Developers, go to /icloud.
Notes and Known Issues
The following issues relate to using iOS SDK 8.0 to develop code.
Fixed in beta 2
Links to Developer websites from an app’s developer page are broken.
Authentication
Known Issue
Projects using LocalAuthentication won’t build if the Destination is set to iOS Simulator.
Known Issues
The API returns incorrect values in some cases.
Use of the AVCaptureDevice method rampToVideoZoomFactor:withRate: will fail.
Use of the new constant, AVCaptureISOCurrent, will result in inconsistent ISO values (as observed on the ISO property) if setExposureModeCustomWithDuration:ISO:completionHandler:is called repeatedly.
In some configurations, the maxBracketedCaptureStillImageCountproperty on AVCaptureStillImageOutput will yield incorrect results.
Fixed in beta 2
Certain apps may crash on launch consistently if they came over from a Restore from Backup.
Known Issue
If you do a clean installation, iCloud Backups may not be completely restored to your device.
Workaround: Use iTunes to back up and restore your iOS 8 beta devices.
Battery Life
Known Issue
Extensive console logging of NCLaunchstats may be a cause of reduced battery life.
Workaround: Launch Notification Center, then reboot the device.
Known Issue
The CoreBluetooth State Preservation & Restoration feature does not work. If your application is jetsammed while in the background performing long-term action(s) with CoreBluetooth, those applications will cease and the application will not be restored.
Bug Reporter
Known Issues
The switch in Developer Settings to hide Bug Reporter is not working.
Workaround: Remove it from the Notification tab in Notification Center settings.
The Bug Reporter icon does not appear on the Home Screen on iPad.
Workaround: Open the app from the Notification tab in Notification Center settings.
The cursor may not get placed in the appropriate text field.

CFPreferences
Known Issue
After memory pressure events, apps and system services may lose their preferences.
Workaround: Reboot the device.
Known Issues
Clients sending multiple simultaneous record update requests to the same zone in the private database may encounter CKErrorZoneBusy errors.
Workaround: Clients should send update requests for a given zone one at a time. In addition, they should handle CKErrorZoneBusy errors by retrying with an exponential back off.
Sometimes, very large syncs may fail.
The Address Book UI people picker has been changed for iOS 8. A new mode with new API has been added where the app does not need access to the user’s contacts and the user will not be prompted for access. A temporary copy of the selected person is returned to the app. See ABPeoplePickerNavigationController.h for more details.
In iOS 8 beta 2, you must use the new mode. The old mode has been deprecated with this beta.
See the new PeoplePicker: Picking a Person or Property sample project demonstrating usage of the new mode.
Known Issue
If the user selects a property from a unified contact, an incorrect person for that property may be returned by the people picker.
Document Providers
Your app needs the iCloud entitlement to be able to be used as a document provider.
Fixed in beta 2
After installing or modifying an existing document provider, you may need to restart the device for it to show in the available document providers.
Import/open causes sandbox denial on first try.
Known Issues
Document provider extensions sometimes crash when trying to import a document from a document provider view controller.

Workaround: Create a local file in the iCloud container and use this URL to move files.
Sometimes, bringing up a Document Provider UI Extension will not show up after redeploying the app via Xcode.
Workaround: Force-quit the app, and then it should appear properly.
FileProvider extensions do not see the host app’s file removed when copying the file to a shared group container.
Extensions
Fixed in beta 2
During a debug session, extensions may time out before loading.
Action extension view controllers do not support full-screen presentation.
Action extensions do not animate smoothly when dismissed.

During a debug session, extensions may time out before loading.
Application extensions may behave unpredictably with respect to location access.
Redeploying an extension may disable it in Notification Center.

Email invitat members can join using push notifications or via inline password entry flow.
A blank screen may be seen after creating a family on iPad.
Workaround: Tap on other settings and then back to iCloud settings.

See Accessing Files and Directories in File System Programming Guide.
Find My Friends
Now that the Share My Location feature is integrated into Messages, Find My Friends only supports the Apple ID configured in Settings & iCloud.

In some cases, using Handoff with Safari will result in an old URL being resumed instead of the current URL.
Known Issues

Phone Calls to and from the Mac may sometimes not complete or send and receive audio.
Fixed in beta 2
HKCorrelationQuery only returns objects that were saved with correlations. It should return all data entries matching the predicate.
Blood pressure readings saved from Health will not have a correlation stored between the systolic and diastolic readings.
Known Issue

Fixed in beta 2
The “primary” property will not be available in HMService in the future.

iCloud Documents & Data managed with iOS 7 or OS X Mavericks will remain unaffected.
iCloud Documents & Data created with iOS 8 Beta will be deleted from the servers at some point during the beta period. Information downloaded and not evicted from the device will remain on device and will re-sync after the data wipe occurs.
The UI for managing iCloud Documents & Data does not show the documents and data for iOS 8 Beta and OS X Yosemite Developer Preview. It only shows the documents and data synced with previous operating systems.
Known Issues
In some cases, signing into iCloud can take up to two minutes.
Newly added files may not sync automatically. After signing into iCloud, reboot the device.
iCloud Keychain

Beginning in iOS 8 beta 2, the NSURLSessionTaskclass provides a new “priority” property with three associated constants: NSURLSessionTaskPriorityDefault, NSURLSessionTaskPriorityLow, and NSURLSessionTaskPriorityHigh. NSURLSessionTask priorities can be used to specify how multiple requests and responses to the same host should be prioritized. Note that the priority is a hint and not a strict guarantee of NSURLSessionTaskperformance.
For complete usage details of NSURLSessionTaskpriorities, refer to the NSURLSession.h header file, which is provided by the Foundation framework.

If an app is using a xib as its main window and is launched in landscape iPad, the main window will have the incorrect dimensions, causing significant distortion and difficulty using presented view controllers. An app may have to be force-quit after presenting a system view controller to function again.
Workaround: Launch all apps in portrait before rotating to landscape.
Subpixel rendering is now on by default for all web content. Websites or in-app web views with extremely tight design constraints may render differently. Solutions for each issue will vary, but use Web Inspector to adjust position, border thickness, and width or height of elements.
In iOS 8.0 beta 2 and later, CSS object model getters (offset{Left|Top|Width|Height} and client{Left|Top|Width|Height}) return fractional double values based on subpixel metrics instead of rounded integral values.
Fixed in beta 2
SecRequestSharedWebCredential and SecAddSharedWebCredential currently only work on device, not in Simulator.
Known Issues
Applications that use Apache Cordova/PhoneGap are broken due to a bug that causes the window.navigator.userAgent object to become undefined when window.navigator is replaced by a pure JavaScript wrapper object.
If you pass NULL for the fqdn parameter of SecRequestSharedWebCredential as recommended, only the first domain in the entitlement is used.
Apps that play video in a UIWebView may fail playback.
Fixed in beta 2
Mapviews do not load tiles in widgets.
