How to add a height/width constraint with iOS Designer in Xamarin Studio?

ios, xamarin, xamarin-studio

Solution

You have to left-click once on the heigth/width pin. Then the constraint is created for you with the current frame size. UPDATE: In current Xamarin, when left-click on "I-bar" pin, you get two choices: (1) "Width" (or Height), which creates a "Constant Width" (Height) e.g. "Width = 100", and (2) "Aspect Ratio", which creates a Width-to-Height constraint, e.g. "Width = 1:1 * Height".

Problem

As the title indicates I want to add a constraint like with Xcode with the Pin button, but there is no such button in Xamarin Studio. I can't figure out where do I add a height constraint. With height constraint I mean a constraint like viewA.height = null * multiplier + constant i.e. `NSLayoutAttribute.NoAttribute` should be used! How can I do that with iOS Designer?
