1.使用只有一个section的TableView来显示LOL 的英雄列表

2.内容包括标题、副标题、图标

3.使用plain样式

heros.plist 文件结构:

 

 

这个其实很简单，直接上代码了

         self.icon = dictionary[@"icon"];
         self.intro = dictionary[@"intro"];
         self.name = dictionary[@"name"];
     }

     return self;
 }

         }

         _heros = herosArray;
     }

     return _heros;

 #pragma mark - 列表方法

 // section数, 默认是1
 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
     return ;
 }

 // 特定section的行数

     return self.heros.count;

     // 必须使用"UITableViewCellStyleSubtitle"才能显示副标题
     UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:nil];

     // 标题
     cell.textLabel.text = hero.name;

     // 副标题
     cell.detailTextLabel.text = hero.intro;

     // 图标
     cell.imageView.image = [UIImage imageNamed:hero.icon];

     return cell;
 }
