本文介绍了一个使用UICollectionView展示网格布局的应用示例。通过UICollectionViewFlowLayout设置每个单元格的尺寸为屏幕宽度减去30后再除以3，实现了自适应屏幕的九宫格布局。文章详细展示了如何初始化UICollectionView，并设置其代理及数据源。

// CollectionViewController.swift

// Created by su on 15/12/8.

import UIKit

class CollectionViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource {

var collectionView: UICollectionView!

override func viewDidLoad() {

super.viewDidLoad()

let flowLayout = UICollectionViewFlowLayout()

flowLayout.itemSize = CGSize(width: (Tools().SCREEN_WIDTH - 30) / 3, height: (Tools().SCREEN_WIDTH - 30) / 3)

collectionView = UICollectionView(frame: self.view.bounds, collectionViewLayout: flowLayout)

collectionView.backgroundColor = UIColor.whiteColor()

collectionView.registerNib(UINib(nibName: "CollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "CollectionViewCell")

collectionView.delegate = self

collectionView.dataSource = self

self.view.addSubview(collectionView)

}

func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {

return 10

}

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

let cell = collectionView.dequeueReusableCellWithReuseIdentifier("CollectionViewCell", forIndexPath: indexPath)

return cell

}

override func didReceiveMemoryWarning() {

super.didReceiveMemoryWarning()

// Dispose of any resources that can be recreated.

}

// MARK: - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

// Get the new view controller using segue.destinationViewController.

// Pass the selected object to the new view controller.

}
