The distribution property and size

- [Instructor] Alignment sets spacing…and alignment perpendicular to the axis.…Distribution sets spacing along the axis.…Though this is a bit more subtle than alignment.…Stop the app.…And take a look at the code for the stack view.…Like fill on the alignment,…fillEqually is the basic automatic mode.…It creates constraints that pin each subview to each other…and sets the size to be equal for all the subviews.…For a vertical axis that's the height,…for a horizontal the width.…

Currently the subviews are flush with one another.…You can add space with the spacing property of UIStackView.…Under distribution here,…add this line.…StackView.spacing…equals 10.…Go ahead and run the app.…Hit Maki Rolls and you'll see you're getting it…at a spacing of 10 between each one of our elements.…

Now you can also get unequal spacing,…and that's a method called setCustomSpacingAfter.…You can go ahead and stop this.…And I'm gonna do another stack view…dot, and this is gonna be setCustomSpacing…with a CGFLoat after UI view.…And we'll do spacing of 20 between backButton and label.…
