UIView breaking in iOS7 but not in iOS8 - ios

Question

I have created a custom view to show 2 labels inside a circle. It is suppose to look like this:
but in iOS 7 it looks like this:
That happens because the constraints hat are supposed to stick the labels to the top/bottom are breaking for some reason, but only on iOS 7. I get the following error:
(
"<NSLayoutConstraint:0x7f96e500a540 H:|-(-1)-[UILabel:0x7f96e2dd84d0] (Names: '|':UIView:0x7f96e2df6350 )>" )
Will attempt to recover by breaking constraint <NSLayoutConstraint:0x7f96e500a540 H:|-(-1)-[UILabel:0x7f96e2dd84d0] (Names: '|':UIView:0x7f96e2df6350 )>
I have confirmed that those are in fact the constraints called (I only gave one error as an example)
self.dayLabelStickButtomConstraint
self.monthLabelStickTopConstraint
Here is the code for the custom view, can anyone maybe understand why is it breaking on iOS 7 but not on 8?

Answer 1

After a lot of messing around the answer lied in the restraints themselves. Once i switched from topMargin,bottomMargin to just top and bottom it worked
