添加按钮图片

• 给 CZMenuItem 模型添加 imageName 属性

    @interface CZMenuItem : NSObject
  
    /// 标题
    @property (nonatomic, strong) NSString *title;
  
    /// 图片名称
    @property (nonatomic, strong) NSString *imageName;
  
    + (instancetype)menuItemWithDict:(NSDictionary *)dict;
  
    @end
  

• 在 CZMenuItemViewModel 创建模型的时候添加对应的图片

    - (NSArray *)composeItems {
        if (_composeItems == nil) {
            NSMutableArray *array = [[NSMutableArray alloc] init];
  
            NSArray *items = @[@{@"title": @"说说", @"imageName": @"tabbar_mood"},
                               @{@"title": @"照片", @"imageName": @"tabbar_photo"},
                               @{@"title": @"日志", @"imageName": @"tabbar_blog"}];
  
            for (NSDictionary *dict in items) {
                CZMenuItem *item = [CZMenuItem menuItemWithDict:dict];
  
                [array addObject:item];
            }
  
            _composeItems = array;
        }
  
        return _composeItems;
    }
  
    - (NSArray *)menuItems {
        if (_menuItems == nil) {
            NSMutableArray *array = [[NSMutableArray alloc] init];
  
            NSArray *items = @[@{@"title": @"全部动态", @"imageName": @"tab_bar_feed_icon"},
                               @{@"title": @"与我相关", @"imageName": @"tab_bar_passive_feed_icon"},
                               @{@"title": @"照片墙", @"imageName": @"tab_bar_pic_wall_icon"},
                               @{@"title": @"电子相框", @"imageName": @"tab_bar_e_album_icon"},
                               @{@"title": @"好友", @"imageName": @"tab_bar_friend_icon"},
                               @{@"title": @"更多", @"imageName": @"tab_bar_e_more_icon"}];
  
            for (NSDictionary *dict in items) {
                CZMenuItem *item = [CZMenuItem menuItemWithDict:dict];
                [array addObject:item];
            }
  
            _menuItems = array;
        }
  
        return _menuItems;
    }
  

• 在 CZMenuViewController 创建按钮的时候设置图片

    for (CZMenuItem *item in self.menuItemVM.menuItems) {
        // stackView添加子控件
        UIButton *button = [[UIButton alloc] init];
  
        button.backgroundColor = [UIColor randomColor];
        [button setTitle:item.title forState:UIControlStateNormal];
        [button setImage:[UIImage imageNamed:item.imageName] forState:UIControlStateNormal];
  
        // 设置按钮的高度
        [button mas_makeConstraints:^(MASConstraintMaker *make) {
            make.height.equalTo(@(60));
        }];
  
        [_menuView addArrangedSubview:button];
    }
