If you've had the same iPhone for a couple of years or more, you've probably started to notice its performance slowing down a little, especially on newer versions of the software. Apple has even been sued for the slow performance in iOS 9 when it is used on an iPhone 4s.
如果你這幾年一直用的是同一部蘋果手機，你一定注意到它的運行速度變慢了，更新到最新系統(tǒng)后尤其如此。甚至曾有用戶因iOS 9操作系統(tǒng)在iPhone 4s上運行太慢而起訴蘋果公司。

But for anyone not up to taking such drastic measures, a solution has emerged that can provide an immediate speed boost by clearing up memory in the phone's App Store.
但不是每個人都愿意采取這樣的過激之舉。對于其他人來說，新的解決辦法已經(jīng)出現(xiàn)了：清空蘋果應(yīng)用商店的內(nèi)存，手機就能立即提速。

San Francisco developer Zachary Dryer shared the hidden trick on Twitter, revealing that pressing a series of buttons in the iOS App Store can get rid of a backlog of stuck app updates.
舊金山程序員扎卡里·德賴爾在推特上分享了這個小竅門。他透露，點擊蘋果應(yīng)用商店的一系列圖形按鈕，可以清空因應(yīng)用更新卡住而積壓的數(shù)據(jù)。

On the App Store, press any one of the five buttons along the bottom of the app 10 times in a row to clear the cached memory. This is data that is meant to be held temporarily but can continue to take up precious resources due to a software error.
在應(yīng)用商店，連續(xù)點擊下方五個按鈕中的任一按鈕十次，可以清空緩存。這些數(shù)據(jù)本該是暫時保存的，但會因為軟件的錯誤而持續(xù)占用寶貴的內(nèi)存。

As long as the same button is pressed in succession, the screen should go white for a couple of seconds and return to the App Store's homepage, with any app update backlogs cleared.
連續(xù)點擊同一個按鈕，手機會白屏幾秒鐘，然后返回到應(yīng)用商店主頁。此時，因應(yīng)用更新而積壓的所有數(shù)據(jù)已被清空。

This is a useful trick if your App Store gets stuck, which can mean app updates not coming through, but should also provide a speed boost. The trick will also work on the iPad.
應(yīng)用商店運行慢時，這招很管用。盡管它意味著應(yīng)用更新失敗了，卻能幫助提速。這招也適用iPad。

According to the developer, the trick works in iTunes, iBooks, App Store and the Apple Watch app, but not in Podcasts, Music, Game Center or iMessage.
這位程序員稱，這招對清理iTunes、iBooks、應(yīng)用商店以及蘋果手表應(yīng)用的緩存都很奏效，但不適用播客、音樂、游戲中心和iMessage應(yīng)用。
