使用Masonry平分布局

开发中经常遇到多个区块需要平分布局，下面列出Masonry自动布局中的平分布局的封装方法

/**
 *  将若干view等宽布局于容器containerView中
 *
 *  @param views         viewArray
 *  @param containerView 容器view
 *  @param LRpadding     距容器的左右边距
 *  @param viewPadding   各view的左右边距
 */

-(void)makeEqualWidthViews:(NSArray *)views inView:(UIView *)containerView LRpadding:(CGFloat)LRpadding viewPadding :(CGFloat)viewPadding
{
    UIView *lastView;
    for (UIView *view in views) {
        [containerView addSubview:view];
        if (lastView) {
            [view mas_makeConstraints:^(MASConstraintMaker *make) {
                make.top.bottom.equalTo(containerView);
                make.left.equalTo(lastView.mas_right).offset(viewPadding);
                make.width.equalTo(lastView);
            }];
        }else
        {
            [view mas_makeConstraints:^(MASConstraintMaker *make) {
                make.left.equalTo(containerView).offset(LRpadding);
                make.top.bottom.equalTo(containerView);
            }];
        }
        
        lastView=view;
    }
    
    
    [lastView mas_makeConstraints:^(MASConstraintMaker *make) {
        
        make.right.equalTo(containerView).offset(-LRpadding);
        
    }];
}
