@interface Tiny_CollectionViewCell : UICollectionViewCell

二、实现我们的CollectViewCell:

// Tiny_CollectionViewCell.m

// Tiny_UICollectionViewController

//

// Created by Tiny on 15-6-16.

#import "Tiny_CollectionViewCell.h"

@implementation Tiny_CollectionViewCell

@synthesize p_w_picpathView;

@synthesize label;

- (id)initWithFrame:(CGRect)frame

{

  self = [super initWithFrame:frame];

  if (self)

  {

    //初始化图片

    self.p_w_picpathView = [[UIImageView alloc] init];

    //定义图片frame

    [self.p_w_picpathView setFrame:CGRectMake(25, 15, 101, 101)];

    [self.contentView addSubview:self.p_w_picpathView];

    //初始化标签

    self.label = [[UILabel alloc] init];

    //定义标签frame

    [self.label setFrame:CGRectMake(35, 121, 150, 20)];

    [self.contentView addSubview:self.label];

  }

  return self;

}

@end

三、定义我们的控制器ViewController:

//

// Tiny_ViewController.h

// Tiny_UICollectionViewController

//

// Created by Tiny on 15-6-16.

// Copyright (c) 2015年 Tiny. All rights reserved.

//

#import <UIKit/UIKit.h>

@interface Tiny_ViewController : UIViewController<UICollectionViewDataSource,UICollectionViewDelegateFlowLayout>

@property(strong, nonatomic) NSArray *events;

@property(strong, nonatomic) UICollectionView *collectionView;

@end

四、实现我们的控制器ViewController:

//

// Tiny_ViewController.m

// Tiny_UICollectionViewController

//

// Created by Tiny on 15-6-16.

// Copyright (c) 2015年 Tiny. All rights reserved.

//

#import "Tiny_ViewController.h"

#import "Tiny_CollectionViewCell.h"

@interface Tiny_ViewController ()

@end

@implementation Tiny_ViewController

- (void)viewDidLoad

{

  [super viewDidLoad];

  // Do any additional setup after loading the view, typically from a nib.

  CGRect screenRect = [[UIScreen mainScreen] bounds];

  NSBundle *bundle = [NSBundle mainBundle];

  NSString *plistPath = [bundle pathForResource:@"events" ofType:@"plist"];

  //获取属性列表文件中的全部数据

  NSArray *array = [[NSArray alloc] initWithContentsOfFile:plistPath];

  self.events = array;

  UICollectionViewFlowLayout *layout= [[UICollectionViewFlowLayout alloc]init];

  self.collectionView = [[UICollectionView alloc]initWithFrame:CGRectMake(0, 0, screenRect.size.width, screenRect.size.height) collectionViewLayout:layout];

  [self.collectionView registerClass:[Tiny_CollectionViewCell class] forCellWithReuseIdentifier:@"Cell"];

  self.collectionView.delegate = self;

  self.collectionView.dataSource = self;

  [self.collectionView setBackgroundColor:[UIColor clearColor]];

  [self.view addSubview:self.collectionView];

}

- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView

{

  return [self.events count] / 2;

}

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section

{

  return 2;

}

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath

{

  Tiny_CollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];

  NSDictionary *event = [self.events objectAtIndex:(indexPath.section * 2 + indexPath.row)];

  cell.p_w_picpathView.p_w_picpath = [UIImage p_w_picpathNamed:[event objectForKey:@"p_w_picpath"]];

  cell.label.text = [event objectForKey:@"name"];

  return cell;

}

#pragma mark - UICollectionViewDelegate

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath

{

  NSDictionary *event = [self.events objectAtIndex:(indexPath.section*2 + indexPath.row)];

  UIAlertView *a = [[UIAlertView alloc] initWithTitle:@"选择项目" message:[NSString stringWithFormat:@"你选了%@项目", [event objectForKey:@"name"]] delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];

  [a show];

}

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath

{

  return CGSizeMake(140, 140);

}

- (void)didReceiveMemoryWarning

{

  [super didReceiveMemoryWarning];

  // Dispose of any resources that can be recreated.

}

@end

五、导入events.plist文件(内容大概如下)
