備註

當您使用 [ Storyboard撰寫AnimationTimeline] 將AnimationClock 、或套用至屬性時, 先前Clock與該屬性相關聯的任何物件都會繼續使用系統資源; 計時系統不會移除時鐘地.When you apply a Storyboard, AnimationTimeline, or AnimationClock to a property by using Compose, any Clock objects previously associated with that property continue to consume system resources; the timing system will not remove the clocks automatically.

若要避免在使用 [撰寫] 套用大量時鐘時發生效能問題, 您應該在完成後, 從動畫屬性中移除撰寫的時鐘。To avoid performance issues when you apply a large number of clocks using Compose, you should remove composing clocks from the animated property after they complete. 有數種方式可以移除時鐘:There are several ways to remove a clock:

這主要是在存留期較長的物件才會發生的動畫問題。This is primarily an issue for animations on objects that have a long lifetime. 記憶體回收物件時,也會中斷連接並記憶體回收其時鐘。When an object is garbage collected, its clocks will also be disconnected and garbage collected.
