//分割线是假的,看着有线,其实没有,由我们来定行数和内容

//协议的两大作用:1.监听 2.设置

//我们需要给tableView指定一个数据源,它负责给tableView提供数据

//注意代理人名称是dataSource,不是delegate

table.dataSource =self;

table.delegate =self;

}

//这两个协议只是用来取内容,数据都是在外界创建

#warning 告诉tableview中第几个section中有几行,section默认一个

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

{

// //分区里有几行

// NSLog(@"%s",__func__);

// //数组的个数和他显示的行数一定要是一一匹配的

return [_tableArraycount];//返回行数

//model类继承与NSObject

}

#warning 给每一个row赋值一个cell,每出现一个新的行,就会走下面的方法,来给这一新的行赋值内容

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

//1.定义重用池的名字,

staticNSString *cellIdentify =@"cell1";

//2.从重用池中取不用的cell,看能不能取出来,

//从以cell1命名的重用池里取

CustomCell *cell = [tableViewdequeueReusableCellWithIdentifier:cellIdentify];

//如果没有,新建一个cell,并放到重用池cell1里

if (!cell) {

cell = [[[CustomCellalloc]initWithStyle:UITableViewCellStyleSubtitlereuseIdentifier:cellIdentify]autorelease];//要加autorelease

}

//3.设置背景颜色,在if外面

[cell setBackgroundColor:[UIColorgreenColor]];

// NSString *path = [[NSBundle mainBundle] pathForResource:@"1" ofType:@"jpg"];

// UIImage *image = [UIImage imageWithContentsOfFile:path];

// cell.imageView.image = image;

// //图片标签

// cell.textLabel.text = @"1";

// //副标签

// cell.detailTextLabel.text = @"2";

// cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;//加右侧箭头

//不用系统的,因为不能满足要用的需求,所以用自定义的cell,定义好了之后要给外界提供接口,为其赋值

// cell.label.text = @"千与千寻";

//2.隐藏断点

//3.跳过断点

//4.走到下一行

//对象po出来,一旦是nil,对象一定没有初始化或赋值或开辟空间

//以后一旦创建一个tableView,就要创建一个数组和他对应,一个tableView对应一个数组

//取数组里的值

// NSString *name = [_tableArray objectAtIndex:indexPath.row];

// cell.label.text = name;

//取字典里的值

NSDictionary *dic = [_tableArrayobjectAtIndex:indexPath.row];

NSString *name = [dicobjectForKey:@"name"];

#warning 明天限时代码创建tableView及实现上面那两个协议,数组里的格式是字典(两个), cell自定义(一个label),没有代码提示
