自动版式的UIScrollView只有垂直 [英] UIScrollView AutoLayout Vertical Only

问题描述

我想要得到的自动版式与的UIScrollView 工作，我用起来有点麻烦了。下面是我所做的：

I want to get the AutoLayout working with the UIScrollView and am having a little trouble with it. Here is what I did:

1. 添加的UIScrollView 主视图与框架内：[顶：0，左：0，宽度：320，高度：568]

1. Add a UIScrollView inside the Main View with frame: [top: 0, left: 0, width: 320, height: 568]

添加的UIView 内容查看中的的UIScrollView 与框架和的bgcolor黑色：[顶：0左：0，宽度：320，高度：568]

Add UIView "ContentView" inside the UIScrollView with frame and bgcolor black: [top: 0, left: 0, width: 320, height: 568]

设置的UIScrollView 约束：[顶：0，底部：0，左：0，右：0]

Setup UIScrollView constraints: [top: 0, bottom: 0, left: 0, right: 0]

设置内容查看约束：[顶：0，底部：0，左：0，右：0]

Setup "ContentView" constraints: [top: 0, bottom: 0, left: 0, right: 0]

对齐里面的内容查看

设置主视图的bgcolor为灰色（看看是怎么回事）

Set Main View bgcolor to gray (to see what's going on)

有关某些原因，限制使内容视图是在屏幕的中间。此外，它滚动在每一个方向。我想内容要滚动只在像的UITableView 垂直方向，使我不能移动它像：的 http://imgur.com/lBCwfAS

For some reason, the constraints make the content view be in the middle of the screen. Also, it scrolls in every direction. I want the content to be scrollable only in vertical direction like in UITableView, so that I can't move it like that: http://imgur.com/lBCwfAS

我是什么做错了吗？我检查了所有的教程和答案，我可以在计算器和谷歌发现，没有人居然有只一个奇怪的问题，所以我寻求帮助。

What am I doing wrong? I have checked all the tutorials and answers I can find in StackOverflow and Google, and no one actually has just a bizarre problem, so I am asking for help.

编辑：我还添加了内容查看的宽度和高度的限制，但这并没有帮助

I also added ContentView's width and height as constraints and that didn't help either.

推荐答案

有关禁用水平滚动，你可以在（无效）scrollViewDidScroll方法设置的内容大小。

For disabling the horizontal scroll, you can set the content size in the (void)scrollViewDidScroll method.

[self.scrollView setContentOffset: CGPointMake(0, self.scrollView.contentOffset.y)];

您还需要设置定向锁定所以只有1滚动方向在同一时间使用。 <一href=\"https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIScrollView_Class/index.html#//apple_ref/occ/instp/UIScrollView/directionalLockEnabled\">https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIScrollView_Class/index.html#//apple_ref/occ/instp/UIScrollView/directionalLockEnabled

You'll also want to set the directional lock so only 1 scroll direction is used at a time. https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIScrollView_Class/index.html#//apple_ref/occ/instp/UIScrollView/directionalLockEnabled

self.scrollView.directionalLockEnabled = YES;
