【问题描述】：

我有一组 UIImageViews。我想单击其中一个并让 imagePickerController 方法为 UIImageView 数组的正确索引设置正确的图像。

var imageArray : [UIImageView]
...
func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject:AnyObject]!){
    //What do I do here?
    self.dismissViewControllerAnimated(true, completion: nil)
}
func pickImage(sender: AnyObject)
{
    var imagePicker = UIImagePickerController()
    imagePicker.delegate = self
    imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    self.presentViewController(imagePicker, animated: true, completion:nil)
    //what do I do here?
}

【解决方案1】：

需要maintain tapped UIImageView 所以当UIImage 从 UIImagePickerController 中被选择时我们可以设置它。说它curImgView

考虑在特定UIImageView为tapped时调用方法：

func pickImage(sender: AnyObject)
{
    //setting currently tapped imageview here
    curImgView = sender;

    var imagePicker = UIImagePickerController()
    imagePicker.delegate = self
    imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    self.presentViewController(imagePicker, animated: true, completion:nil)
}

现在选择图像时：

func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject:AnyObject]!){

    //set image here
    curImgView.image = 'image here';
    self.dismissViewControllerAnimated(true, completion: nil)
}
