How to add / use default icons to navigation bar
You can use UIBarButtonSystemItem
this way:
let button = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Refresh, target: self, action: "someAction")
navigationItem.leftBarButtonItem = button
Result for leftBarButtonItem
:
If you want to set it at right side you can use this code:
navigationItem.rightBarButtonItem = button
Result for rightBarButtonItem
:
Swift: These are the most commonly used options:
To Use custom image with original colour:
let customImageBarBtn1 = UIBarButtonItem(
UIImage(named: "someImage.png").withRenderingMode(.alwaysOriginal),
style: .plain, target: self, action: #selector(handleClick))
To Use custom image with tint colour:
let customImageBarBtn2 = UIBarButtonItem(
UIImage(named: "someImage.png").withRenderingMode(.alwaysTemplate),
style: .plain, target: self, action: #selector(handleClick))
Or use system provided buttons:
let systemBarBtn = UIBarButtonItem(
barButtonSystemItem: .search,
target: self, action: #selector(handleClick))
Then add any one of these buttons to the navigationItem:
navigationItem.leftBarButtonItems = [customImageBarBtn1, customImageBarBtn2]
navigationItem.rightBarButtonItems = [systemBarBtn]
// OR you can use this if there's only one item.
navigationItem.rightBarButtonItem = systemBarBtn
For custom Images: As a starting size, 22ptx22pt
images work well for the default iPhone Navigation Bar size.
In swift 4.3
let btnRefresh = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.refresh, target: self, action: #selector(targeted function to invoke))
//If you want icon in left side
navigationItem.leftBarButtonItem = btnRefresh
//If you want icon in right side
navigationItem.rightBarButtonItem = btnRefresh
