I am currently having difficulty with AutoLayout. I am using interface builder and am trying to position two buttons of equal width side by side as illustrated in the following image.
From the following Preview image, my titleImage has been properly constrained and is displaying correctly however the buttons are not. I have experimented by aligning button 1 with the leading edge of titleImage, and button2 with the trailing edge of titleImage, however the width distribution between the two buttons becomes skewed at this point, as demonstrated below.
My objective is to understand what constraints are missing and should be applied to the two buttons to maintain equal widths regardless of device. If possible I would like to achieve this through interface builder as opposed to additional code.

If you select Aspect Ratio for multiple items, Auto Layout chooses the width of one of the items for the numerator and the height of another item for the denominator. To change the initial aspect ratio, edit the Multiplier field of the Attributes inspector for the constraint.
Auto Layout defines margins for each view. These margins describe the preferred spacing between the edge of the view and its subviews. You can access the view's margins using either the layoutMargins or layoutMarginsGuide property. The layoutMargins property lets you get and set the margins as a UIEdgeInsets structure.
Auto Layout is a constraint-based layout system. It allows developers to create an adaptive interface that responds appropriately to changes in screen size and device orientation.
Auto Layout constraints allow us to create views that dynamically adjust to different size classes and positions. The constraints will make sure that your views adjust to any size changes without having to manually update frames or positions.
Note: Auto Layout makes internationalization easy, too. You no longer have to make new XIBs or storyboards for every language you wish to support, including right-to-left languages such as Hebrew or Arabic. At first, Apple made one screen size for the iPhone.
Build and run the app and tap the buttons to see how they behave. Perform the test in both portrait and landscape orientations. The lower button is center-aligned in the window, horizontally. The lower button sits 8 points from the bottom of the window. The top button is 40 points above the lower button and aligned with the lower button.
The buttons always have the same width, regardless of which has the largest label. When both labels are short, the buttons will shrink equally. Unless a constraint prevents it, buttons will size themselves to fit their content.
Making apps that look good in any orientation across multiple devices can be a challenge. If you’ve experienced this kind of frustration, despair no longer! Auto Layout makes it easy to support different screen sizes in your apps.
