ZLDropdownMenu

---

This version is the original version, I will add more function for it in the future. You can use ZLDropdownMenu to set the condition what you want to filter. If you have any advice or problem, please issue me.

Usage

---

First, you should set the datasource and delegate.

    ZLDropDownMenu *menu = [[ZLDropDownMenu alloc] init];
    [self.view addSubview:menu];
    menu.delegate = self;
    menu.dataSource = self;
    [menu mas_makeConstraints:^(MASConstraintMaker *make) {
        make.top.equalTo(topView.mas_bottom);
        make.left.right.equalTo(self.view);
        make.height.mas_equalTo(50);
    }];

Second, you should implement the corresponding method.

- (NSInteger)numberOfColumnsInMenu:(ZLDropDownMenu *)menu;
- (NSInteger)menu:(ZLDropDownMenu *)menu numberOfRowsInColumns:(NSInteger)column;
- (NSString *)menu:(ZLDropDownMenu *)menu titleForColumn:(NSInteger)column;
- (NSString *)menu:(ZLDropDownMenu *)menu titleForRowAtIndexPath:(ZLIndexPath *)indexPath;
- (void)menu:(ZLDropDownMenu *)menu didSelectRowAtIndexPath:(ZLIndexPath *)indexPath;

if you wanna change the UI, plese reset ZLDropDownMenuUICalc 、ZLDropDownMenuTitleButton and ZLDropDownMenuCollectionViewCell.

#效果图

#使用方法

ZLDropDownMenu *menu = [[ZLDropDownMenu alloc] init];
[self.view addSubview:menu];
menu.delegate = self;
menu.dataSource = self;
[menu mas_makeConstraints:^(MASConstraintMaker *make) {
    make.top.equalTo(topView.mas_bottom);
    make.left.right.equalTo(self.view);
    make.height.mas_equalTo(50);
}];
遵守代理ZLDropDownMenuDelegate和数据源ZLDropDownMenuDataSource，并按照ViewController中设置即可，使用方法和UITableview相似
