约束照顾不同的iPhone / iPad尺寸的图像xcode 7 beta 4

Question

I'm new to iOS development, so setting constraints for objects on the storyboard in Xcode has been difficult for me.

As this picture below shows, I have 3 borders for buttons I created in sketch so they are all images, each of them inside of a image view:

I tried adding constraints by pinning all three images to the left, right and below themselves but I got errors for it and it did not come out right at all on the simulators. All of the images are in aspect fill mode, and I have the view in the size of an iPhone 4 when I put the images in the storyboard. Here's an example of what it looks like in the iPhone 6 simulator without any constraints:

What are the constraints I need so that it looks okay for all iPhone and iPad sizes and looks like it does in the storyboard? And landscape mode will not be a part of this application, so that will not need to be accounted for.

Answer 1

You can also use button 1 equal width constraint and button 2 equal width constraint
