Storyboard¶

IBOutlets being referenced as weak references since the main parent object would be strong reference and it would deallocated all of its child IBOutlets when it goes off its screen.

iOS 6 also deprecated -viewDidUnload which was used before in Obj - C to set the UIViews to nil

self.aSubView = nil;
