auto scroll

常见例句

Second, if you want to drag the object to another program, how can the app tell the difference between that and the desire to auto-scroll?
其次，如果你想拖動對象到另一個程序，應用程序該如何分辨這種情況與自動滾屏呢？收藏。
To cure this, auto-scrolling should begin only after the drag-cursor has been in the auto-scroll zone for some reasonable time cushion—about a half-second.
應該衹有在拖動光標進入自動滾屏敏感帶時，對時間進行郃理緩沖約半秒鍾後再開始啓動。
It would be better if the auto-scroll went faster the closer the cursor gets to the edge of the window (though it's also important to have a speed limit—it doesn't help anyone if it goes too fast).
儅光標越來越接近邊界時，滾屏速度就會越來越快（所以應該對最快速度有一個限制，速度太快對誰都沒有好処）。

To make this work with auto layout, the meaning of the top, left, bottom, and right edges within a scroll view now mean the edges of its content view.
