Adding constraints to a UIBarButtonItem

Question

Xcode is not allowing me to put constraints on my BarButtonItem on a ViewController in the MainStoryBoard. It\'s appearing too far to the left where it\'s unrea

Answer 1

Try this:

let rightConstraint = NSLayoutConstraint(item: your_item_here, attribute: .Right, relatedBy: .Equal, toItem: your_item_here, attribute: .Left, multiplier: 0, constant: 1)
your_item_here.addConstraint(rightConstraint)

P.S if you want to add constraint to your UIBarButtonItem, it will rise an error

Value of type 'UIBarButtonItem' has no member 'addConstraint'

P.S.S

Because of it is not a view class, you can't apply constraints to it.
