Tableview presented modally and autolayout

Question

I have a problem with auto layout when I open a table view which is presented modally, in fact my current situation is the following:

I'm developing an app using swift and I'd like to solve this problem with autolayout but currently I can't because it appears to be disabled.

Can somebody help me please? Thanks in advance.

在此屏幕中单击红色虚线以选择要添加的约束（顶部，底部，前导，尾随）

Answer 2

Looks like you have not selected UI Element for which you want to set auto-layout constraint. Please select Label/Textfield and then add constraint as per your requirement. I hope this helps.
