问题 I'm building an app for fun with a initial view controller of a tableview, where you are able to see the details of the cells, and add new data to the tableview.

问题 I used this tutorial http://www.wannabegeek.com/?p=168 for swiping between different view controllers (which are on my storyboard). Now I want to unload the views from the view controllers when a didReceiveMemoryWarning is received. I've tried this: - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. self.view = nil; } And when I receive a memory warning, the view shows black. How can I recover the view from my storyboard? 回答1:
