How to use info button on a UIBarButtonItem?

How can I use the info light on a UIBarButtonItem?

I don't want to use a custom image because the result is not very nice.

I would like to use the Apple "info" button on a UIBarButtonItem using Swift.

Solution

  • There is no direct way to create such a bar button using the UIBarButtonItem APIs.

    You can although use a custom view configured with a .InfoLight UIButton, as suggested here:

    // Create the info button
let infoButton = UIButton(type: .infoLight)

// You will need to configure the target action for the button itself, not the bar button itemr
infoButton.addTarget(self, action: #selector(getInfoAction), for: .touchUpInside)

// Create a bar button item using the info button as its custom view
let infoBarButtonItem = UIBarButtonItem(customView: infoButton)

// Use it as required
navigationItem.rightBarButtonItem = infoBarButtonItem
