table范例

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    //创建一个模拟从coreData创建的数据
    NSMutableArray *data = [NSMutableArray arrayWithObjects:
                            [NSDictionary dictionaryWithObjectsAndKeys:@"宫保鸡丁", @"name", @"鸡丁、辣椒", @"Element", @"小鸟依人", @"author", @"pic01", @"image", nil],
                            [NSDictionary dictionaryWithObjectsAndKeys:@"辣子鸡块", @"name", @"鸡丁、辣椒", @"Element", @"小鸟依人", @"author", @"pic01", @"image", nil],
                            [NSDictionary dictionaryWithObjectsAndKeys:@"小炒肉丝", @"name", @"鸡丁、辣椒", @"Element", @"小鸟依人", @"author", @"pic01", @"image", nil], nil];
    //全局的数据对象
    cookData = data;
}

//table内容的列数
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [cookData count];
}

//table cell的创建
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *cookTableId = @"cookTable";
    //从内存池中取出已存在cell
    mxdCookCell *cell = (mxdCookCell *)[tableView dequeueReusableCellWithIdentifier:cookTableId];
    //如果不存在则创建
    if (cell == nil) {
        //通过自定义的cookCell.xib模板创建cell
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"cookCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
    }
    //数据填充
    NSDictionary *cookCell = [cookData objectAtIndex:indexPath.row];
    cell.cookName.text = [cookCell objectForKey:@"name"];
    cell.cookElement.text = [cookCell objectForKey:@"Element"];
    cell.cookAuthor.text = [cookCell objectForKey:@"author"];
    //查询image所在路径
    NSString *path = [[NSBundle mainBundle] pathForResource:[cookCell objectForKey:@"image"] ofType:@"jpg"];
    cell.cookImage.image = [UIImage imageWithContentsOfFile:path];
    return cell;
}

//设置cell高度
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    return 72;
