Iphone - How to Edit Empty Spaces of Left, Right UIBarButtonItem in UINavigationBar

To edit the empty spaces around UIBarButtonItems in a UINavigationBar on iOS, you can adjust the UIBarButtonItem's width property. However, directly setting the width of UIBarButtonItems is not directly supported. Instead, you can achieve this by embedding the UIBarButtonItem in a UIView and adjusting the constraints of that UIView.

Here's how you can do it programmatically:

// Create your UIBarButtonItems let leftBarButtonItem = UIBarButtonItem(title: "Left", style: .plain, target: self, action: #selector(leftButtonTapped)) let rightBarButtonItem = UIBarButtonItem(title: "Right", style: .plain, target: self, action: #selector(rightButtonTapped)) // Create a flexible space UIBarButtonItem to push other items to the edges let flexibleSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil) // Embed UIBarButtonItems in UIViews to allow for constraint adjustments let leftBarButtonView = UIView(frame: CGRect(x: 0, y: 0, width: 50, height: 44)) // Adjust width as needed leftBarButtonView.addSubview(leftBarButtonItem.customView!) leftBarButtonItem.customView?.translatesAutoresizingMaskIntoConstraints = false leftBarButtonItem.customView?.leadingAnchor.constraint(equalTo: leftBarButtonView.leadingAnchor).isActive = true leftBarButtonItem.customView?.trailingAnchor.constraint(equalTo: leftBarButtonView.trailingAnchor).isActive = true leftBarButtonItem.customView?.topAnchor.constraint(equalTo: leftBarButtonView.topAnchor).isActive = true leftBarButtonItem.customView?.bottomAnchor.constraint(equalTo: leftBarButtonView.bottomAnchor).isActive = true let rightBarButtonView = UIView(frame: CGRect(x: 0, y: 0, width: 50, height: 44)) // Adjust width as needed rightBarButtonView.addSubview(rightBarButtonItem.customView!) rightBarButtonItem.customView?.translatesAutoresizingMaskIntoConstraints = false rightBarButtonItem.customView?.leadingAnchor.constraint(equalTo: rightBarButtonView.leadingAnchor).isActive = true rightBarButtonItem.customView?.trailingAnchor.constraint(equalTo: rightBarButtonView.trailingAnchor).isActive = true rightBarButtonItem.customView?.topAnchor.constraint(equalTo: rightBarButtonView.topAnchor).isActive = true rightBarButtonItem.customView?.bottomAnchor.constraint(equalTo: rightBarButtonView.bottomAnchor).isActive = true // Assign UIBarButtonItems to navigationItem navigationItem.leftBarButtonItems = [flexibleSpace, UIBarButtonItem(customView: leftBarButtonView)] navigationItem.rightBarButtonItems = [flexibleSpace, UIBarButtonItem(customView: rightBarButtonView)]

Adjust the width of the leftBarButtonView and rightBarButtonView to change the spacing around the UIBarButtonItems. This approach allows you to customize the empty spaces around the UIBarButtonItems in the UINavigationBar.
