Hiding not working when there's more than one height/width constraint

[jakubknejzlik]

I don't know if it's wanted behaviour, but view can have more than one constraints with same type. When I add two constraints for height, only the first is zeroed when hideByHeight (same applies for width).

In your case it's not the wanted behaviour, you're right. But with the current category, we can use the "hide" method only one constraint (height or width).

To fix this you can modify the method - (void)hideView:(BOOL)hidden byAttribute:(NSLayoutAttribute)attribute . The hack used in this method is to save the old value of the constraint in the "alpha" property... but as you set two constraints, the second value erase the first one...

I've checked the code already and it should be easy fix...wanna pull request?:)
