真正的多任務

????多任務，或者說讓多個應用程序同時運行，這無疑是蘋果極為看重的一點。應用間的切換非常迅速，但美中不足的是，基于節電的考慮，蘋果禁止了大部分第三方應用在后臺更新數據。多任務界面也進行了重新設計，圖標變得更大了，用戶可以更方便地在應用之間進行切換。

Real multitasking

????Multitasking for iOS users, or the ability to have several apps running at once, was a distinctly Apple experience. Switching from app to app was quick, but many third-party apps couldn't update with new information in the background, something Apple mostly disallowed in favor of battery life. A new multitasking screen treats many open apps as larger panes to swipe through.
