iOS版：setContentSize引起我的整个框架的UIScrollView跳 [英] iOS: setContentSize is causing my entire UIScrollView frame to jump
本文介绍了iOS版：setContentSize引起我的整个框架的UIScrollView跳的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
有可能是一个简单的解决这个问题，我失踪，但我似乎无法找到病因。
问题：我每次打电话setContentSize我的滚动视图，它使整个滚动视图帧转移。
问：为什么它的位置每次都重设setContentSize叫？以及如何得到它停止？
的注：的
- 滚动视图中的contentOffSet是罚款。这是整个
滚动视图帧跳跃到其原来的位置。 - 滚动视图是为了向上和向下按钮preSS，露出了里面的UIView的。
- 这工作得很好，但在打开一个单元格时，和CollapseClick本身（滚动视图）调用setContentSize，整个滚动视图跳回了prematurely - 任何意见将是AP preciated。谢谢你。
布局：
- 简单的布局：1滚动视图（全屏），为的UIView 1容器（身高：120点）的出现和消失的滚动型上下移动。

解决方案
有一个简单的解决方案：关闭自动布局
对于我来说，我没有把它关掉了我的整个故事板，只是我在加载的笔尖。（打算用来作为整个网站的小部件。）问题解决了。
在WWDC 2012的视频会话228 - 为掌握自动布局的最佳实践。解释和解决这个问题，开始在30m45s
There is probably a simple solution to this problem that I'm missing, but I can't seem to find the cause.
Problem: Every time I call setContentSize on my scroll view, it causes the entire scrollview frame to shift.
Question: Why does its position reset every time setContentSize is called? and how do I get it to stop?
Notes:
- The contentOffSet within the Scrollview is fine. It's the entire scrollview frame that jumps to its original position.
- The scroll view is meant to move up and down with a button press, revealing the UIView underneath. -- This works fine, but when a cell is opened, and CollapseClick calls setContentSize on itself (the scrollview), the entire scrollview jumps back up prematurely
- Any advice would be appreciated. Thanks.
Layout:
- Simple Layout: 1 scrollview(full screen), 1 container for UIView(height: 120 point) that appears and disappears as the Scrollview moves up and down.

self.postShoutContainer.alpha = 1;
myCollapseClick.frame= newCCFrame;

解决方案
There was a simple solution: Turn off Auto-layout.
For me, I didn't turn it off for my whole storyboard, just a nib I had loaded in. (intended to be used as a widget throughout the site.) Problem solved.
The WWDC 2012 video "Session 228 - Best Practices for Mastering Auto Layout" explains and addresses the problem, starting at 30m45s.
