+/// The `customView` will be layouted correctly according to the selected style & the current device
+/// state (rotation, status bar visibility, etc.). The background will still be styled & layouted
+/// according to the provided style. If your custom view requires custom touch handling,
+/// make sure to set `style.canTapToHold` to `false`. Otherwise the `customView` won't
+/// receive any touches, as the internal `gestureRecognizer` would receive them.
+///
+/// - Parameters:
+///   - customView: A custom UIView to display as notification content.
+///   - styleName: The name of the style. You can use styles previously added using e.g. ``addStyleNamed:prepare:``.
+///                If no style can be found for the given `styleName` or it is `nil`, the default style will be used.
+///   - completion: A ``JDStatusBarNotificationPresenterCompletionBlock``, which gets called once the presentation animation finishes.
