老样子，先附上两张效果图

• 首先自定义一个继承于FFDropDownMenuBasedModel的菜单模型
  .h文件

#import <FFDropDownMenuBasedModel.h>
@interface FFDropDownCustomMenuStyle1Model : FFDropDownMenuBasedModel
/** 主标题的背景颜色 */
@property (nonatomic, strong) UIColor *mainTitleBgColor;
/** 主标题 */
@property (nonatomic, copy) NSString *mainTitle;
/** 副标题 */
@property (nonatomic, copy) NSString *subTitle;
//菜单模型创建的属性用于自定义菜单cell，所以需要什么属性，自己定义

@end

.m文件

#import "FFDropDownCustomMenuStyle1Model.h"
@implementation FFDropDownCustomMenuStyle1Model
@end

• 其次自定义一个继承于FFDropDownMenuBasedCell的cell

FFDropDownCustomMenuStyle1Cell.h

#import <FFDropDownMenuView.h>
/**  
 *  自定义菜单效果1 菜单 cell  
 */
@interface FFDropDownCustomMenuStyle1Cell : FFDropDownMenuBasedCell
@end

FFDropDownCustomMenuStyle1Cell.m

#import "FFDropDownCustomMenuStyle1Cell.h"
//model
#import "FFDropDownCustomMenuStyle1Model.h"
@interface FFDropDownCustomMenuStyle1Cell ()
@property (weak, nonatomic) IBOutlet UILabel *mainTitle_Label;
@property (weak, nonatomic) IBOutlet UILabel *subTitle_Label;
@[email protected] FFDropDownCustomMenuStyle1Cell
- (void)setMenuModel:(id)menuModel {      
    _menuModel = menuModel;    
    //在这里将模型转成自定义的模型    
    FFDropDownCustomMenuStyle1Model *realModel = (FFDropDownCustomMenuStyle1Model *)menuModel;    
    self.mainTitle_Label.backgroundColor = realModel.mainTitleBgColor;    
    self.mainTitle_Label.text = realModel.mainTitle;    
    self.subTitle_Label.text = realModel.subTitle; }
@end

cell的xib布局图如下

• 最后就可以创建下拉菜单了

#import "FFDropDownCustomMenuStyle1VC.h"
//controller
#import "FFDropDownMenuNextPageVC.h"
//view
#import <FFDropDownMenuView.h>
//model
#import "FFDropDownCustomMenuStyle1Model.h"
@interface FFDropDownCustomMenuStyle1VC ()
/** 下拉菜单 */
@property (nonatomic, strong) FFDropDownMenuView *dropDownMenu;
@[email protected] FFDropDownCustomMenuStyle1VC
- (void)viewDidLoad {    
    [super viewDidLoad];      
    [self createDropdownMenu];      
    [self setupNav];
}
- (void)createDropdownMenu {    
    NSArray *menuModelsArr = [self getDropDownMenuModelsArray];    
    self.dropDownMenu = [FFDropDownMenuView new];    
    //设置动画效果,可以根据项目需求设置自己所需要的动画效果
    self.dropDownMenu.menuAnimateType = FFDropDownMenuViewAnimateType_FallFromTop;    
    //若不需要灰色透明蒙板，下面的两个透明度可以设置为0     self.dropDownMenu.bgColorbeginAlpha = 0;    
    self.dropDownMenu.bgColorEndAlpha = 0;    
    //设置下拉菜单的宽度为整个屏幕的宽度     self.dropDownMenu.menuWidth = [UIScreen mainScreen].bounds.size.width;    
    //设置菜单距离屏幕右边的边距为0     self.dropDownMenu.menuRightMargin = 0;    
    //取消菜单圆角效果     self.dropDownMenu.menuCornerRadius = 0;    
    //隐藏三角形     self.dropDownMenu.triangleSize = CGSizeZero;    
    self.dropDownMenu.eachMenuItemHeight = 70;    
    self.dropDownMenu.menuModelsArray = menuModelsArr;    
    self.dropDownMenu.cellClassName = @"FFDropDownCustomMenuStyle1Cell.xib";    
    self.dropDownMenu.menuItemBackgroundColor = FFColor(255, 255, 255, 0.7);    
    [self.dropDownMenu setup]; }
/** 获取下拉菜单模型数组 */
- (NSArray *)getDropDownMenuModelsArray {
