[iOS基础控件

A.需求

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

4.使用MVC模式

 

 

heros.plist 文件结构:

 

 

这个其实很简单，直接上代码了

//  LOLHero

- (instancetype) initWithDictionary:(NSDictionary *) dictionary;
+ (instancetype) heroWithDictionary:(NSDictionary *) dictionary;

    if (self = [super init]) {
        self.icon = dictionary[@"icon"];
        self.intro = dictionary[@"intro"];
        self.name = dictionary[@"name"];
    }
   
    return self;
}

+ (instancetype) heroWithDictionary:(NSDictionary *) dictionary {
    return [[self alloc] initWithDictionary:dictionary];
}

+ (instancetype) hero {
    return [self heroWithDictionary:nil];
}

        }
       
        _heros = herosArray;
    }
   
    return _heros;
}

#pragma mark - 列表方法

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

// 特定section的行数
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return self.heros.count;
}


// 特定行的内容
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    Hero *hero = self.heros[indexPath.row];
   
    // 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;
}
