Create UICollectionViewController, uicollectionview

Problems encountered during collection view development. Because the page is in the storyboard, you can directly set its layout, cell size, and other attributes in the storyboard.

In addition, the UICollectionViewController has four init methods:

-(Id) initWithNibName :( NSString *) nibNameOrNil bundle :( NSBundle *) nibBundleOrNil {}

-(Id) initWithCollectionViewLayout :( UICollectionViewLayout *) layout {}

-(Id) initWithCoder :( NSCoder *) aDecoder {}

-(Id) init {}

However, because the controller is defined directly in the storyboard, only the initWithCoder :( NSCoder *) aDecoder method in the Code is called, and the other three are not called.
