UIScrollview 自动布局问题

问题描述

我的自动布局(可能)和我的滚动视图有问题！

I have a problem with autolayout(maybe) and my scrollview!

我的问题

1. 我向下滚动

2.然后我推送到另一个视图

2.Then I push to another View

3.然后我回去，滚动视图看起来像那样，我无法滚动到最高点.(我在滚动视图的弹跳中看到它)

3.Then I go back and the scrollview looks like that and I'm not able to scroll to the highest point.(I see it in the bouncing of the scrollview)

谁能帮帮我?

推荐答案

包含视图控制器中的以下代码片段似乎也解决了这个问题，而不依赖于显式大小:

The following code snippet in the containing view controller also seems to solve the problem, without relying on explicit sizes:

- (void)viewDidDisappear:(BOOL)animated {
  [super viewDidDisappear:animated];
  self.mainScrollView.contentOffset = CGPointZero;
}

它确实将内容偏移量重置为原点，但其他答案似乎也是如此.

It does reset the content offset to the origin, but it seems that so do the other answers.
