九宫格在iOS项目UI中是经常会出现的，在这里写了一个简单的for循环创建九宫格，供新手参考。

#pragma mark - createNineSquare- (void)createNineSquare {    UIView *btnViewBackground = [[UIView alloc] initWithFrame:CGRectMake(0, bannerImageView.size.height, kDeviceWidth, 3*(kDeviceWidth-3)/4)];    btnViewBackground.backgroundColor = [UIColor lightGrayColor];    [self.view addSubview:btnViewBackground];        CGFloat btnMargin = 1; //间隔    CGFloat btnWidth = (kDeviceWidth-3)/4;  //宽    CGFloat btnHeight = (kDeviceWidth-3)/4; //高        for (int i = 0; i<12; i++) {        int row = i/4; //行        int col = i%4; //列        btnView = [[UIView alloc] init];        btnView.frame = CGRectMake(col*(btnWidth + btnMargin), row*(btnHeight + btnMargin), btnWidth, btnHeight);        btnView.backgroundColor = [UIColor whiteColor];        [btnViewBackground addSubview:btnView];                UIImageView *btnImageView = [[UIImageView alloc] initWithFrame:CGRectMake(btnWidth/3, 15, btnWidth/3, btnWidth/3)];        btnImageView.image = [UIImage imageNamed:[NSString stringWithFormat:@"%@",self.btnImageArray[i]]];        [btnView addSubview:btnImageView];                UILabel *btnLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, btnWidth/3+25, btnWidth, 30)];        btnLabel.backgroundColor = [UIColor clearColor];        btnLabel.textAlignment = NSTextAlignmentCenter;        btnLabel.textColor = [UIColor blackColor];        btnLabel.text = [NSString stringWithFormat:@"%@",self.btnLabelTitleArray[i]];        btnLabel.font = kSystemFont_14;        [btnView addSubview:btnLabel];                button = [UIButton buttonWithType:UIButtonTypeCustom];        button.frame = CGRectMake(col*(btnWidth + btnMargin), row*(btnHeight + btnMargin), btnWidth, btnHeight);        button.backgroundColor = [UIColor clearColor];        button.tag = 1000+i;        [button addTarget:self action:@selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside];        [btnViewBackground addSubview:button];    }    }

这是一个简单的九宫格类型的Button 以及对应的图片和标题。
