【非凡程序员】 OC第十六节课 初识IOS开发四 (九宫格游戏）

九宫格游戏：先是定义一个二维数组，写出正确的九宫格，而后随机的交换横行的两组，在随机隐藏几个数据。让用户输入数据，再进行判断是否正确

ViewController.h文件：

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
- (IBAction)DaWan:(id)sender;

@property (weak, nonatomic) IBOutlet UITextField *ShengFu;
@property (weak, nonatomic) IBOutlet UITextField *Number9;
@property (weak, nonatomic) IBOutlet UITextField *Number8;
@property (weak, nonatomic) IBOutlet UITextField *Number7;
@property (weak, nonatomic) IBOutlet UITextField *Number6;
@property (weak, nonatomic) IBOutlet UITextField *Number5;
@property (weak, nonatomic) IBOutlet UITextField *Number4;
@property (weak, nonatomic) IBOutlet UITextField *Number3;
@property (weak, nonatomic) IBOutlet UITextField *Number2;
@property (weak, nonatomic) IBOutlet UITextField *Number1;
@property (nonatomic,strong) NSMutableArray *finish; //定义全局变量
- (IBAction)Begin:(id)sender;
@end

ViewController.m文件：

#import "ViewController.h"
