我有一个UITableViewCell按钮来拍摄图像并将其放回单元格中。当我调用UIImagePickerController并拍摄图像时，它不会调用以下委托：
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject], sender:AnyObject)
这是我takePhotoFunction的UITableViewController：
@IBAction func takePhoto(sender: AnyObject) {
let imagePickerController = UIImagePickerController()
imagePickerController.delegate = self
imagePickerController.allowsEditing = true
let actionSheet = UIAlertController(title: "Choose image souruce", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
actionSheet.addAction(UIAlertAction(title: "Take Image", style: UIAlertActionStyle.Default, handler: { (alert:UIAlertAction!) -> Void in
imagePickerController.sourceType = UIImagePickerControllerSourceType.Camera
self.presentViewController(imagePickerController, animated: true, completion: nil)
}))
actionSheet.addAction(UIAlertAction(title: "Photo Library", style: UIAlertActionStyle.Default, handler: { (alert:UIAlertAction!) -> Void in
imagePickerController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
self.presentViewController(imagePickerController, animated: true, completion: nil)
}))
actionSheet.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: nil))
self.presentViewController(actionSheet, animated: true, completion: nil)}
在Swift 3中，此委托方法现在称为：
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
不同之处在于：
我遇到了同样的问题，当我进行这些更改时，它起作用了。
