save a view with NSUserDefaults {iPhone SDK}

i try to use NSUserDefault or something like 开发者_如何学Pythonthis , to save a specific view after quit from application and when user lunch application again load from that view ... but i dont know how!

I would suggest you have a look at the NSCoder class and its related components. The API is specifically built for arching and dearchiving Objective-C class instances.
