ios - How to put a Bar button item to the bottom of a toolbar? -

i have toolbar @ top of app. changed height programmatically make bit bigger.

    var consth = nslayoutconstraint(item: toolbar, attribute: nslayoutattribute.height,     relatedby: nslayoutrelation.equal, toitem: nil,      attribute: nslayoutattribute.notanattribute, multiplier: 1, constant: 64)     toolbar.addconstraint(consth) 

but have problem when add bar button items via storyboard, automatically centers them vertically. standard items stay @ bottom. how solve?

[please answer in swift]

you should hook bar button items using iboutlets, can add spacing using edge insets:

barbutton.imageinsets = uiedgeinsetsmake(0,10,0,0)
