防止子视图在UIScrollView中滚动 [英] Prevent subview from scrolling in a UIScrollView

问题描述

我有一个 UIScrollView 子类与某个子视图我想防止滚动（当所有其他子视图滚动正常）。

I have a UIScrollView subclass with a certain subview I'd like to prevent from scrolling (while all the other subviews scroll as normal).

我可以想到的最接近的例子是 UITableView 的右边的索引条（查看联系人应用程序参见示例）。我猜这是一个子视图的表（scrollview），但它不会随着用户滚动移动。

The closest example to this I can think of is UITableView's "index strip" on the right side (look in the Contacts app to see an example). I am guessing this is a subview of the table (scrollview) but it does not move as the user scrolls.

我似乎不能让我的子视图保持放！

I can't seem to make my subview stay put! How can I accomplish this?

推荐答案

诀窍是调整非滚动子视​​图的框架 -layoutSubviews 。

The trick is to adjust the frame of the "non-scrollable" subview inside -layoutSubviews.
