3、events.plist，04，05

4、CQ38ViewController.h

#import <UIKit/UIKit.h>@interface CQ38ViewController : UICollectionViewController@property (strong,nonatomic) NSArray *events;@end

 

5、CQ38ViewController.m

#import "CQ38ViewController.h"#import "CQ38CollectionViewCell.h"@interface CQ38ViewController ()@end@implementation CQ38ViewController- (void)viewDidLoad{    [super viewDidLoad];    // Do any additional setup after loading the view, typically from a nib.
