Constraints in Xcode 8

Question

I'm trying to pin all labels and buttons using auto layout. But it seems to be impossible. I've tried almost everything (tutorials also - been there done that), and it still sucks. On every device (Iphone 7plus, 6) it looks much different, sometimes labels hide, or disappear. Please, help.

my labels:

• log in/sign up
• email address
• password
• skip

text field:

• 2, under email address and password

background:

• image view

Answer 1

I've created a storyboard with one view controller in it. it contains what should be the correct constraints.

try using that view.
