如上图所示，一款高大上的下拉列表给大家看看！！！

PTLDownMenuList

下拉列表

简单用法

PTLMenuButton *btn = [[PTLMenuButton alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 40) menuTitles:@[@"科室",@"排序"]];
    NSArray * listArr1 = @[@"全科",@"妇产科",@"儿科",@"内科",@"外科",@"中医科",@"口腔科",@"耳科",@"耳鼻喉科"];
    NSArray * listArr2 = @[@"综合排序",@"评分",@"问诊量",@"价格"];
    btn.listTitles = @[listArr1, listArr2];
    btn.delegate = self;
    [self.view addSubview:btn];

遵循PTLMenuButtonDelegate代理协议

-(void)ptl_menuButton:(PTLMenuButton *)menuButton didSelectMenuButtonAtIndex:(NSInteger)index selectMenuButtonTitle:(NSString *)title listRow:(NSInteger)row rowTitle:(NSString *)rowTitle{
    NSLog(@"index: %zd, title:%@, listrow: %zd, rowTitle: %@", index, title, row, rowTitle);
}
