• 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;

@end

@implementation 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;

@end

@implementation 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 {
    __weak typeof(self)weakSelf = self;
    
    FFDropDownCustomMenuStyle1Model *menuModel1 = [FFDropDownCustomMenuStyle1Model new];

    menuModel1.mainTitle = @"1";
    menuModel1.subTitle = @"First Menu Item";
    menuModel1.menuBlock = ^ {

    menuModel2.mainTitle = @"2";
    menuModel2.subTitle = @"Second Menu Item";
    menuModel2.menuBlock = ^ {

    };
    
    FFDropDownCustomMenuStyle1Model *menuModel5 = [FFDropDownCustomMenuStyle1Model new];
    menuModel5.mainTitleBgColor = FFColor(0, 119, 195, 1);
    menuModel5.mainTitle = @"5";
    menuModel5.subTitle = @"Fifth Menu Item";

/** 初始化导航栏 */
