macOS NStableView的基本操作

先睹为快。看到效果在学习，进步会更快！

点击搜索后

选中请求返回项，还可以鼠标右键显示菜单栏。

这是一个简单的搜索框 + 按钮 + 列表 + 右键菜单栏

我们来看看代码

1.#import "ViewController.h"

#import <Cocoa/Cocoa.h>

@interface ViewController : NSViewController


@end

2.ViewController.m

#import "ViewController.h"
#import "Masonry.h"//没有导入Masonry框架的也可以使用原生布局
#import "MarketTableViewCell.h"
