UIScrollView和约束 [英] UIScrollView and Constraints

问题描述

我试图在UIScrollView的顶部放置一个UIImageView，当我将UIScrollView约束到View控制器的两侧，并将UIImageView约束到顶部，并使UIImageView的宽度等于其UIScrollView UIImageView方式比UIScrollView宽，并且比预期高得多。任何想法我做错了什么？

解决方案

检查是否向您的数据视图添加了以下约束：

1. 转到故事板 - >选择视图


2. 现在在右下角，您可以看到小按钮添加约束。


3. 选择固定并标记所有边的所有4个约束


4. 将全部4个约束添加到视图中

EDIT

我已按照您的说明创建了一个演示。

I'm trying to place a UIImageView at the top of a UIScrollView and when I constrain the UIScrollView to the sides of the View Controller and constrain the UIImageView to the top and make the width of the UIImageView equal to the UIScrollView it makes the UIImageView way wider than the UIScrollView, and much taller than expected. Any idea what I'm doing wrong?

解决方案

Check that following constraints are added to your view:

1. Go to Storyboard -> Select your view
2. Now at right-bottom corner you can see small buttons to add constraints
3. Select "Pin" button
4. And mark all 4 constraints for all sides
5. Add all 4 constraints to your view

EDIT

I have created one demo as you described.

ImageConstraint Demo

Set all constraints for UIScrollView and UIImageView and works perfectly.

Below are reference images for you.

Storyboard:

FOLLOW BELOW STEPS

Step - 1 : In storyboard Select UIView -> Editor -> Resolve layout issues

Step - 2 : Repeat same to add constraint

Step - 3 : Select UIScrollView and add constraint from right-bottom corner

Step - 4 : Select UIImageView and add constraint for it.
