Good way to display a folder in ViewController

i need to display a folder in myViewController same as displaying folder in our System/Computer. and also i need to drag a image to this folder.i have folder named as static in app-bundle. so when i drag a image on to the folder,need to save the dragged image to app-bundle static 开发者_C百科folder.

i know the code to save.however what is the best method to display a folder in myViewController.is it like a button with folder image or any controller to show a folder?

i think can use - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event; to drag a image over folder.and check if it touches the folder frame .if yes,save it to the appbundle.is it a good way?and can any one tell me a good way to display a folder in myViewController.

My suggestion is pan gesture instead of touches moved.you can implement same as like your desktop.take an image and place in your view controller and give action for the image and whenever any object touches your static folder(already we placed image) change the touched object path.its so simple seems to be.

I feel like you are asking the wrong question. From the user's perspective, iOS doesn't have a filesystem or folders or files or save buttons. Sure, you could create a view that looks like a folder with files in it... but you shouldn't.

My recommendation is that you rethink your design and accomplish what you need to do by using the new iOS paradigms instead of trying to replicate the old desktop paradigms.
