Change size of UIBarButtonItem (image) in Swift 3

Question

I am trying to change the size of some icons in my navBar, but I am a little confused as to how to do this? My code so far is:

func setUpNavBarButtons() {
          


        

Answer 1

You can configure the bar buttons using this function:

public convenience init(customView: UIView)

And You can init the custom view as You desire. After that You can access the view if needed via UIBarButtonItem's:

open var customView: UIView?

Hint: Because UIButton is a child class of UIView, You can directly use it too.
