    }

    //添加彩种按钮

    for (int i= 0; i<2; i++) {

        for (int j = 0; j<4; j++) {

            if (i == 1&&j==3) {

                break;

            }

            UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];

            [btn setBackgroundImage:[UIImage imageNamed:@"btn_white_small"] forState:UIControlStateNormal];
