Size Class Issues - Also need a size class key

问题:

In Xcode I am having an issue with the size classes in my app. I am unable to get the right size classes to show that seem to work for all of my different devices. I kind of would like a key to see what the size classes should really be, also the size classes don't seem to really match up.

Below is an image attached of an example. I can't get anything correct. I am new to this and I know that I am doing something wrong.

Also, I tried this: https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/LayoutandAppearance.html but it didn't match up. Maybe my controls have a layout issue?

Edit: Shown below, I can't modify the leading edges and trailing edges...

Whoo Hooo!!! I figured it out!!! @nburk, I want to give you some credit too. You said the key words trailing space and leading space so I googled more on that, and I was seeing the wrong thing.

I want to recommend this to all users who are having problems with it. I didn't realize that dragging the constraints using the control button would actually do it.
