ios - 有没有办法让枚举返回 UIViewController

Question

有没有办法让枚举返回 UIViewController，而不仅仅是字符串或整数？

enum MyEnum {
    case movie
    case music
    case notes

    var viewController: UIViewController {
        case .movie: return MovieViewController
        case .music: return MusicViewController
        case .notes: return NotesViewController
    }
}

是的，你可以这样做：

enum MyEnum {
case movie
case music
case notes

var viewController: UIViewController {
    
    switch self {
  
    case .movie: return MovieViewController()
    case .music: return MusicViewController()
    case .notes: return NotesViewController()
    default: break
  }
 }
}
