与scrollView相关的Autolayout问题

Question

I have implemented a ScrollView.
I want to switch between to Views.
Because it's such simple UI stuff, I just take one Controller and use the hidden attribute to switch between the two views. Furthermore, I want to position some labels and the views. However I can't center them, they are positioned too far on the right side. I think my constraints are right. Do you know how to solve this issue?

Answer 1

According to your layout i've tried creating similar kind of layout.

What you need to do is add Container View as SubView of UIScrollView.

Constraints to Scroll View:

You need to set top,reading,trailing and Height constraints.

Constraints to Container View:

You need to set leading,top,trailing and bottom constraints.
You need to set _Height Equally_ to scroll View.
You need to set _Width Equally_ to View.

Constraints to Label:

1.) Label 2 Constraints:

You need to set **Center Horizontally and center Vertically**.

2.) Label 1 Constraints:

You need to set **Leading space**.

// I’ve set leading space: 10
You also need to set center Y to label 2.

3.) Label 3 Constraints:

You need to set **Trailing space**.

// I’ve set leading space: 10
You also need to set center Y to label 2.

Constraints to Image View:

You need to set height,width and Vertical Space Constraints.
you also need to set center Horizontally to View.

Hope this help you to solve your problem.
