初始化对象
WSDropMenuView *dropMenu = [[WSDropMenuView alloc] initWithFrame:CGRectMake(0, 60, self.view.frame.size.width, 40)];
dropMenu.dataSource = self;
dropMenu.delegate =self;
[self.view addSubview:dropMenu];
实现代理方法 (简单易用 , 不繁琐)
- (NSInteger)dropMenuView:(WSDropMenuView *)dropMenuView numberWithIndexPath:(WSIndexPath *)indexPath; //dataSource
- (NSString *)dropMenuView:(WSDropMenuView *)dropMenuView titleWithIndexPath:(WSIndexPath *)indexPath //dataSource
- (void)dropMenuView:(WSDropMenuView *)dropMenuView didSelectWithIndexPath:(WSIndexPath *)indexPath //delegate
