你不知道的iPhone提速小竅門
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，你一定注意到它的執行速度變慢了，更新到最新系統後尤其如此。甚至曾有使用者因iOS 9作業系統在iPhone 4s上執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.
但不是每個人都願意採取這樣的過激之舉。對於其他人來說，新的解決辦法已經出現了：清空蘋果應用商店的記憶體，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.
舊金山程式設計師扎卡里·德賴爾在推特上分享了這個小竅門。他透露，點選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資料。
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，連續點選下方五個按鈕中的任一按鈕十次，可以清空快取。這些資料本該是暫時儲存的，但會因為軟體的錯誤而持續佔用寶貴的記憶體。
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.
連續點選同一個按鈕，手機會白屏幾秒鐘，然後返回到應用商店主頁。此時，因應用更新而積壓的所有資料已被清空。
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.
應用商店執行慢時，這招很管用。儘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.
這位程式設計師稱，這招對清理iTunes、iBooks、應用商店以及蘋果手錶應用的快取都很奏效，但不適用播客、音樂、遊戲中心和iMessage應用。
