最近突然想写一个2048的小游戏，由于全部是自定义控件，所以程序看起来冗杂，但是核心的算法部分还是很不错的，大家感兴趣的可以仔细看看。
声明部分：
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
@property(nonatomic,strong) IBOutlet UILabel *label;
@property(nonatomic,strong) IBOutlet UILabel *label1;
@property(nonatomic,strong) IBOutlet UILabel *label2;
@property(nonatomic,strong) IBOutlet UILabel *label3;
@property(nonatomic,strong) IBOutlet UILabel *label4;
@property(nonatomic,strong) IBOutlet UILabel *label5;
@property(nonatomic,strong) IBOutlet UILabel *label6;
@property(nonatomic,strong) IBOutlet UILabel *label7;
@property(nonatomic,strong) IBOutlet UILabel *label8;
@property(nonatomic,strong) IBOutlet UILabel *label9;
@property(nonatomic,strong) IBOutlet UILabel *label10;
@property(nonatomic,strong) IBOutlet UILabel *label11;
@property(nonatomic,strong) IBOutlet UILabel *label12;
@property(nonatomic,strong) IBOutlet UILabel *label13;
@property(nonatomic,strong) IBOutlet UILabel *label14;
@property(nonatomic,strong) IBOutlet UILabel *label15;
@end
