当有两列数据是双列表，并且其数据数量不同时，在切换列时出现崩溃 about dopdropdownmenu-enhanced

[12207480]

我在项目中没有这个问题 是不是你数目row item 判断问题 ，还有请给出奔溃信息

[czzhengkw]

我测试的数据是
// 数据
self.classifys = @[@"美食",@"今日新单",@"电影",@"酒店"];
self.cates = @[@"自助餐",@"快餐",@"火锅",@"日韩料理",@"西餐",@"烧烤小吃"];
self.movices = @[@"内地剧",@"港台剧",@"英美剧"];
self.hostels = @[@"经济酒店",@"商务酒店",@"连锁酒店",@"度假酒店",@"公寓酒店"];
self.areas = @[@"全城",@"芙蓉区",@"雨花区"];
self.areas1 = @[@"全城",@"芙蓉区",@"雨花区"];
self.sorts = @[@"默认排序",@"离我最近",@"好评优先",@"人气优先",@"最新发布"];

下面是修改测试的两个方法

• (NSInteger)menu:(DOPDropDownMenu *)menu numberOfItemsInRow:(NSInteger)row column:(NSInteger)column
  {
  if (column == 0) {
  if (row == 0) {
  return self.cates.count;
  } else if (row == 2){
  return self.movices.count;
  } else if (row == 3){
  return self.hostels.count;
  }
  }else if(column == 1){
  return 3;
  }
  return 0;
  }
• (NSString *)menu:(DOPDropDownMenu *)menu titleForItemsInRowAtIndexPath:(DOPIndexPath *)indexPath
  {
  if (indexPath.column == 0) {
  if (indexPath.row == 0) {
  return self.cates[indexPath.item];
  } else if (indexPath.row == 2){
  return self.movices[indexPath.item];
  } else if (indexPath.row == 3){
  return self.hostels[indexPath.item];
  }
  }else if(indexPath.column == 1){
  return self.areas1[indexPath.item];
  }
  return nil;
  }

下面是错误信息
