How to do match_parent in iOS

Question

I am used to having an Android background where I do:

android_layout_width="match_parent" or android_layout_height="match_parent"

How is this behavior done on iOS, using xib?

Answer 1

1) Set frame of child view matching parent's view bounds.
2) Enable autoresizing mask like in screenshot.

Answer 2

You have to create two constraints from the child to it's parent view:

• equal width
• equal height

It's also possible to define a margin (select the created constraint within the size inspector)
