图03
3、events.plist,如图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.
