可可滚动视图在文件中间的特立独行的情况下不断弹跳 [英] Cocoa Scroll view keeps bouncing on mavericks in the middle of the file

问题描述

有人知道为什么在向上滚动和向下滚动时（通过两根手指触摸）它经常捕捉并在滚动视图的中间错误地反弹吗？此行为非常令人讨厌，并导致不良的用户体验。

Does anybody know why when scrolling (via two finger touch) rapidly up and down it "catches" quite often and bounces incorrectly in the middle of a scrollview? This behavior is quite annoying and makes for a bad user experience.

Xcode的滚动视图可水平和垂直弹动，并且几乎不会像这样卡住。

Xcode has scrollviews which bounce both horizontally and vertically and doesn't nearly-as-often get stuck this way.

推荐答案

这似乎是NSScrollView中的错误。

That seems like a bug in NSScrollView.

您可以启用主要的轴滚动功能，这基本上可以消除问题：

You can enable predominant axis scrolling, which mostly eliminates the problem:

scrollView.usesPredominantAxisScrolling = YES;

或者，您可以禁用水平反射，这是Finder的作用：

Or, you can disable horizontal bouncing, which is what Finder does:

scrollView.horizontalScrollElasticity = NSScrollElasticityNone;
