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，更新到最新系統后尤其如此。甚至曾有用戶因iOS 9操作系統在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，新的解決辦法已經出現了：清空蘋果應用商店的內存，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，點擊蘋果應用商店的一系列圖形按鈕，可以清空因應用更新卡住而積壓的數據。

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.

在應用商店，連續點擊下方五個按鈕中的任一按鈕十次，可以清空緩存。這些數據本該是暫時保存的，但會因為軟件的錯誤而持續占用寶貴的內存。

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.

連續點擊同一個按鈕，手機會白屏幾秒鐘，然后返回到應用商店主頁。此時，因應用更新而積壓的所有數據已被清空。

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.

應用商店運行慢時，這招很管用。盡管它意味著應用更新失敗了，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、應用商店以及蘋果手表應用的緩存都很奏效，但不適用播客、音樂、游戲中心和iMessage應用。
