Custom Menu Items

Sheeeeeeeeet can be extended with custom menu item types.

If you want to use entire custom views, you can use the built-in CustomItem to use custom UIViews in a custom action sheet. The demo app shows you how to do this.

However, CustomItem can be pretty complicated to setup and requires custom xib files.

Instead, you can inherit any of the built-in item types and make it use any custom item cell when you present them in a custom action sheet.

For instance, the custom type below inherits the standard MenuItem base class and makes it use another cell type:

class MultilineItem: MenuItem {

    override func actionSheetCell(for tableView: UITableView) -> ActionSheetItemCell {
        DemoMultilineItemCell(style: actionSheetCellStyle)
    }
    
    override var actionSheetCellType: ActionSheetItemCell.Type {
        DemoMultilineItemCell.self
    }
}

The custom cell type inherits the standard ActionSheetItemCell base class and enables multiline support when it's refreshed:

class MultilineItemCell: ActionSheetItemCell {
    
    override func refresh() {
        super.refresh()
        textLabel?.numberOfLines = 0
    }
}

You can then also adjust the cell's appearance to make it appear taller than other cells

class CustomAppearance: ActionSheetAppearance {
    
    override func apply() {
        super.apply()
        MultilineItemCell.appearance().height = 100
    }

You can test this custom item in the demo app.
