Ios 带ImageView的UIImagePickerController

我试图从照片库中获取图像，但我有一个问题。我有3个不同的图像视图。在这些图像视图上有3种不同的点击手势。我需要选择不同的照片，并显示给用户

我该怎么办？

• 将UINavigationControllerDelegate、UIImagePickerControllerDelegate添加到控制器
• 创建UITap手势的函数

  func createTapGesture(selectorName: String) -> UITapGestureRecognizer {
  
      return UITapGestureRecognizer(target: self, action: Selector(selectorName))
  }
  
  func imageTap(sender: AnyObject) {
  
      currentImageView = sender.view as! UIImageView
      pickImage()
  }
  

• 显示图像PickerView

  func pickImage() {
  
      let imagePicker = UIImagePickerController()
      imagePicker.delegate = self
      imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
      imagePicker.allowsEditing = false
      self.presentViewController(imagePicker, animated: true, completion: nil)
  }
  
  func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage, editingInfo: [String : AnyObject]?) {
  
      dismissViewControllerAnimated(true, completion: nil)
      currentImageView.image = image
  }
  

• 将这些代码添加到viewDidLoad

  firstImageView.addGestureRecognizer(createTapGesture("imageTap:"))
  secondImageView.addGestureRecognizer(createTapGesture("imageTap:"))
  thirdImageView.addGestureRecognizer(createTapGesture("imageTap:"))
  

• 在IB中，确保已选中图像视图集

  用户交互功能

希望这能有所帮助

谢谢回复。我如何定义currentImageView您可以帮助currentImageView是一个UIImageView，您可以在全局中定义。这样你就可以在任何地方使用它。
