masonry多个平均布局

/首先添加5个视图
 NSMutableArray *array = [NSMutableArray new];
    for (int i = 0; i < 5; i ++) {
        UIView *view = [UIView new];
        view.backgroundColor = [UIColor greenColor];
        [self addSubview:view];
        [array addObject:view]; //保存添加的控件
    }

//水平方向控件间隔固定等间隔
[array mas_distributeViewsAlongAxis:MASAxisTypeHorizontal withFixedSpacing:15 leadSpacing:10 tailSpacing:10];
            [array makeConstraints:^(MASConstraintMaker *make) {
                make.top.equalTo(50);
                make.height.equalTo(70);
            }];

//水平方向宽度固定等间隔
[array mas_distributeViewsAlongAxis:MASAxisTypeHorizontal withFixedItemLength:70 leadSpacing:10 tailSpacing:10];
            [array makeConstraints:^(MASConstraintMaker *make) { //数组额你不必须都是view
                make.top.equalTo(50);
                make.height.equalTo(70);
            }];
