66.九宫格布局

//    每个item宽高

    CGFloat W = 90;

    CGFloat H = 110;

//    每行列数

    NSInteger rank = 4;

//    每列间距

    CGFloat rankMargin = (self.view.frame.size.width-rank *W)/(rank-1);

//    每行间距

    CGFloat rowMargin = 30;

//    item索引-->根据需求改变索引

    NSUInteger index = 9;

    for (int i=0; i<index; i++) {

//     Item  X轴

        CGFloat X = (i%rank)*(W+rankMargin);

        CGFloat Y = (i/rank)*(H+rowMargin);

//        Item top

        CGFloat top = 50;

        UIImageView *imageV = [[UIImageView alloc]init];

        imageV.image = [UIImage imageNamed:@"IMG_1170 2"];

        imageV.frame = CGRectMake(X, Y+top, W, H);

        [self.view addSubview:imageV];
