為什么更新iOS 8的人越來越少

????蘋果（Apple）設備用戶下載最新移動操作系統iOS 8的速度正在放緩，明顯不敵前幾個版本，這顯示出對于新系統首發時出現的程序漏洞，用戶似乎仍然心有余悸。

????周二，科技巨頭蘋果公司在其開發者網站上發布了一組最新數據。數據顯示，自iOS 8操作系統于9月17日高調發布以來，所有的蘋果移動設備中僅有47%已在運行新版系統。這與去年iOS 7發布時的盛況形成了鮮明對比——根據數據分析服務商Mixpanel的統計，同樣是在發布后兩周半的時間里內，iOS 7的用戶下載率達到了70%。

????用戶對蘋果最新移動操作系統反應謹慎，原因很可能出在iOS 8的漏洞重重上。在名為iOS 8.0.1的小幅更新版本推出后，很多用戶反映，更新后通話和網絡功能受到影響，蘋果的指紋識別技術Touch ID也無法使用，這使得iOS 8.0.1一下子處于風口浪尖。蘋果對此迅速作出反應，立刻從應用商店下架了新版系統，并修復了漏洞，在一天半之后發布了修訂版供用戶下載。

????新版系統的問題對蘋果而言無疑是一次沉重的打擊，該公司本欲借新款智能手機iPhone 6 和 iPhone 6 Plus發布之際，向用戶隆重推出這款新的操作系統，沒想到最后卻演變成了一場公關危機。

????顯然，早期升級用戶所遇到的問題讓相當一部分的iOS用戶顧慮重重，不敢貿然更新從蘋果提供的數據中不難看出這一點：新版系統發布后不到一周，蘋果就曾宣稱，所有的iPhone、iPad和 iPod設備中，運行iOS 8系統的用戶比例占到46%。但是截至本周，這一數字僅增加了1%。（財富中文網）

????Apple device owners are slower to download iOS 8, the latest mobile software update, than previous updates, indicating that they may be scared off by a buggy and embarrassing launch.

????On Tuesday, the tech giant revealed new data on its developer support web site indicating that 47% of all Apple mobile devices currently run iOS 8, which was released on Sept. 17 to much fanfare. That’s compared with iOS 7, which was downloaded by 70% of user during the same two and a half week period last year according to the data analytics service Mixpanel.

????The likely reason behind slower adoption of Apple’s latest mobile software has to do with iOS 8 itself. A small, incremental software update to iOS 8, dubbed iOS 8.0.1, quickly made headlines after many users complained that it disabled cell and data service, as well as Apple’s fingerprint-recognition technology, Touch ID. Apple quickly pulled the update from its app store, fixed the bug and made it publicly available a day-and-a-half later.

????The problems with the update marked a major stumble for Apple, which had hoped to showcase the new operating system while selling the latest versions of its smartphone, the iPhone 6 and iPhone 6 Plus. Instead, it turned into a public relations nightmare.

????It’s clear a significant number of iOS users remain wary about suffering the same kind of glitches that some early adopters did. Case in point: Less than a week after its release, Apple reported that iOS 8 was running on 46% of all iPhones, iPads and iPods. But as of this week, that figure saw a mere 1% uptick.
