ユーレカフォームの行を使用してviewControllerを表示する方法

Question

ユーレカは異なるデータ型を含む新しいレコード（MediaPicker）を作成するために使用されるため、viewControllerの表示方法が不思議です。

ジョブを実行する行はどれですか？ PushRowまたはButtonRow

これは私がこれを作成しようとする私のクラスです。

import UIKit 
import MediaPlayer 

import Eureka 

public final class MusicRow<T: Equatable> : SelectorRow<T, PushSelectorCell<T>, SelectorViewController<T>>, RowType { 

    public required init(tag: String?) { 
     super.init(tag: tag) 
     presentationMode = .Show(controllerProvider: ControllerProvider.Callback { 
      return AddMusicViewController(){ _ in } 
      }, completionCallback: { vc in 
       vc.navigationController?.popViewControllerAnimated(true) 
     }) 
    } 
} 

public class AddMusicViewController: MPMediaPickerController, MPMediaPickerControllerDelegate { 

    var musicPicker: MPMediaPickerController! 

    public var row: RowOf<MPMediaItemCollection>! 

    public var completionCallback : ((UIViewController) ->())? 

    public override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view. 
     // Setup sections/rows for tableView 
     addMusic() 
    } 

    // Initialize musicPicker and customize it 
    func addMusic() { 
     musicPicker = MPMediaPickerController.self(mediaTypes:.Music) 
     musicPicker.delegate = self 
     musicPicker.allowsPickingMultipleItems = true 
     view.addSubview(musicPicker.view) 
    } 

    // After selection, store the data into an array 
    public func mediaPicker(mediaPicker: MPMediaPickerController, didPickMediaItems mediaItemCollection: MPMediaItemCollection) { 
     musicTemp = nil 
     musicTemp = mediaItemCollection 
     if musicTemp == nil { 
      noMusic = true 
     } else { 
      noMusic = false 
     } 
     completionCallback?(self) 
    } 

    // Cancel mediaPickerController 
    public func mediaPickerDidCancel(mediaPicker: MPMediaPickerController){ 
     // Dismiss the picker if the user canceled 
     noMusic = true 
     completionCallback?(self) 
    } 
} 

以下は、私が直面しているエラーです。

Answer 1

が、これは私の要件はMPMediaPickerControllerを使用していた、一般的な質問でした。

以下は私の設定です。

import UIKit 
import MediaPlayer 

import Eureka 

// MusicRow 
public final class MusicRow : SelectorRow<MPMediaItemCollection, PushSelectorCell<MPMediaItemCollection>, AddMusicViewController>, RowType { 
    public required init(tag: String?) { 
     super.init(tag: tag) 
     presentationMode = .Show(controllerProvider: ControllerProvider.Callback { return AddMusicViewController(){ _ in } }, completionCallback: { vc in vc.navigationController?.popViewControllerAnimated(true) }) 
displayValueFor = { 
     guard var musicTitle = $0 else { return "" } 
     musicTitle = musicTemp! 
     let representativeItem = musicTitle.representativeItem 
     print("representativeItem = \(representativeItem)") 
     let representativeItemTitle = representativeItem?.title 
     return "\(representativeItemTitle)" 
     } 
    } 
} 

// MusicViewController 
public class AddMusicViewController : UIViewController, TypedRowControllerType, MPMediaPickerControllerDelegate { 

    public var row: RowOf<MPMediaItemCollection>! 
    public var completionCallback : ((UIViewController) ->())? 

    lazy var musicPicker : MPMediaPickerController = { [unowned self] in 
     let mediaPicker = MPMediaPickerController.self(mediaTypes:.Music) 
     return mediaPicker 
    }() 

    required public init?(coder aDecoder: NSCoder) { 
     super.init(coder: aDecoder) 
    } 

    public override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) { 
     super.init(nibName: nil, bundle: nil) 
    } 

    convenience public init(_ callback: (UIViewController) ->()){ 
     self.init(nibName: nil, bundle: nil) 
     completionCallback = callback 
    } 

    public override func viewDidLoad() { 
     super.viewDidLoad() 
     view.addSubview(musicPicker.view) 

     musicPicker.delegate = self 
     musicPicker.allowsPickingMultipleItems = true 

     self.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "", style: .Plain, target: nil, action: nil) 
    } 

    // After selection, store the data into a temporary variable 
    public func mediaPicker(mediaPicker: MPMediaPickerController, didPickMediaItems mediaItemCollection: MPMediaItemCollection) { 
     musicTemp = nil 
     musicTemp = mediaItemCollection 
     if musicTemp == nil { 
      noMusic = true 
     } else { 
      noMusic = false 
      row.value? = musicTemp! 
     } 
     completionCallback?(self) 
    } 

    // Cancel mediaPickerController 
    public func mediaPickerDidCancel(mediaPicker: MPMediaPickerController){ 
     // Dismiss the picker if the user canceled 
     noMusic = true 
     completionCallback?(self) 
    } 
} 

私は誰の個人的な要求にそれを微調整することは困難ではないと信じています！
