將UIImage傳遞給另一個視圖控制器的單元格

Question

我試圖將UIImage()變量的內容傳遞給下一個視圖控制器的單元格。

基本上我的佈局是這樣的：

的圖像在ControllerA加載，然後保存在一個模型。

在下一個控制器中，加載一個TableViewCell。

我想要在單元格內加載圖片。

我該如何做到這一點？

我的代碼：

第一部分：

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 

    // Save the poem. 
    savePoem() 
} 

func savePoem() { 
    // Save the poem current completion date. 
    poem.date = NSDate() 

    // Save the theme name for the poem. 
    poem.theme = theme.name 

    // Save the currently displayed picture. 
    poem.image = ImageView.image 

    poem.words = textField.words 

    // Make the poem object persist. 
    PoemPersistence.sharedInstance.persistPoem(poem) 
} 

細胞加載圖片：

func configureWithPoem(poem: Poem) { 
    themeLabel.text = "#\(poem.theme)" 
    poemLabel.text = poem.words 
    pictureImageView.image = poem.image 
} 

func capturePoemImage() -> UIImage { 
    // Hide the share button. 
    shareButton.hidden = true 

    // Capture a PNG of the view. 
    UIGraphicsBeginImageContextWithOptions(frame.size, false, 0) 
    layer.renderInContext(UIGraphicsGetCurrentContext()!) 
    let containerViewImage = UIGraphicsGetImageFromCurrentImageContext() 
    UIGraphicsEndImageContext() 

    // Show the share button. 
    shareButton.hidden = false 

    return containerViewImage 
} 

元得以在第二控制器中加載：

func poemCellWantsToSharePoem(poemCell: PoemCell) { 
    // Find the poem displayed at this index path. 
    let indexPath = tableView.mp_indexPathForCell(poemCell) 
    let poem = poems[indexPath.row] 

    // Generate the image of the poem. 
    let poemImage = poemCell.capturePoemImage() 

Answer 1

，如果你只要你使用prepareForSegue（）將數據發送到下一個UIViewController - 將segue創建到下一個控制器（control + Drag），然後爲該標識符指定一個名稱。

• 現在通過聲明

  @IBOutlet weak var imageView:UIImageView! 
      var image:String ? 
  override func viewDidLoad() 
  { 
      imageView.image = image  
  } 
  

  這一形象變量將接收數據然後將其分配給@IBOutlet設置你的目標控制器。

  func prepareForSegue (segue:UIStoryboardSegue, sender:AnyObject?) 
      { 
  
       if segue.identifier == "NAMEOFSEGUEIDENTIFIER" 
       { 
        let destinationController = segue.destinationViewController as! NAMEOFTHEDESTIONCONTROLLER 
        let indexPath = tableView.indexPathForSelectedRow! 
       // now the data structure that contains your information, use it there 
        let data = dataContainer[indexPath.row] 
  
       // i noticed that you might be using struct so 
       // let's passed the picture from that specific row to the next conroller 
       destinationController.image = data.image 
       } 
      } 
  

我希望幫助:)
