因为今天项目需要用选择类别的视图，主要实现的界面就是点击，下面弹出一个视图，有两级列表可选择！！而且可以上下滑动！用的时候将这个类SkyAssociationMenuView导入项目中，开始上代码！！！很简单，将数组的数据换一下就行了！！
#import "ViewController.h"
#import "SkyAssociationMenuView.h"
#define kScreenWidth [UIScreen mainScreen].bounds.size.width
#define kScreenHeight [UIScreen mainScreen].bounds.size.height
// 414
#define kScale kScreenWidth/375.0f
#define kkScale kScreenWidth/414.0f
#define khScale kScreenHeight/667.0f
@interface ViewController ()
{
NSArray *titleArr;
NSArray *datArr;
UIButton *btn;
}
@property (strong, nonatomic) SkyAssociationMenuView *tagView;
@end
@implementation ViewController

self.view.backgroundColor = [UIColor whiteColor];
//需要的传的数组
