Adding buttons to toolbar programmatically in swift
The usual way to do that is to create the array of toolbar items and then assign the array to the items
property of the toolbar.
self.navigationController?.isToolbarHidden = false
var items = [UIBarButtonItem]()
items.append(
UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
)
items.append(
UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(onClickedToolbeltButton(_:)))
)
toolbarItems = items
Here is an example with MKUserTrackingBarButtonItem
:
navigationController?.toolbarHidden = false
let barButtonItem = MKUserTrackingBarButtonItem(mapView: self.mapView)
self.toolbarItems = [barButtonItem]
None of the above worked for me, but:
Swift 3 / Swift 4
self.navigationController?.isToolbarHidden = false
var items = [UIBarButtonItem]()
items.append( UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: self, action: nil) )
items.append( UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(add)) ) // replace add with your function
self.toolbarItems = items // this made the difference. setting the items to the controller, not the navigationcontroller
self.navigationController?.toolbarItems = items
self.navigationController?.setToolbarItems(items, animated: false)
self.navigationController?.toolbar.setItems(items, animated: false)
Try it.
self.navigationController?.toolbarHidden = false
var items = [UIBarButtonItem]()
items.append(
UIBarButtonItem(barButtonSystemItem: .FlexibleSpace, target: self, action: nil)
)
items.append(
UIBarButtonItem(barButtonSystemItem: .Add, target: self, action: "onClickedToolbeltButton:")
)
self.navigationController?.toolbar.setItems(items, animated: false)
