使用imagePicker将拾取的图像附加到数组中

Question

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {            
        selectedImageArray.append(pickedImage)            
    }        
    dismissViewControllerAnimated(true, completion: nil)        
}

我希望将选中的图像放入selectedImageArray中，但是没有得到图像。

要获取已选择的图像，您必须使用 NSMutableArray

创建一个公共数组并在其中添加对象。

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])
{
    // assign pickup image into varibale
    var selectedimage : UIImage!
    if let editedImage = info[UIImagePickerControllerEditedImage] as? UIImage
    {
        selectedimage = editedImage
    }
    else
    {
        selectedimage = info[UIImagePickerControllerOriginalImage] as? UIImage
    }
    self.testArray.addObject(selectedimage)
}
