今天给同学们带来，通过storyboard自带的cell创建界面并且一个tableView可以绑定和创建不同的cell,那么废话不多说！直接上代码先看效果图！

// 2.加载数组

#warning - 完全需求驱动开发先写好内部最基层的模型然后如何传递如何使用我们就来实现

// 1.创建cell

ZZAppCell *cell = [tableView dequeueReusableCellWithIdentifier:@"app"];

cell.delegate = self;

// 这一步不需要写为什么？我们用的是通过storyboard来创建cell那么他的流程是

// 1:先通过标识去缓存池中取

// 2:如果没有那么他就去storyboard中通过这个标识找如果有就照着这个模子刻出来

// if (cell == nil) {

// cell = [[ZZAppCell alloc] init];

// }

// 2.给cell传递模型

cell.app = self.apps[indexPath.row];

// 3.返回cell

return cell;

}

{

[tableView deselectRowAtIndexPath:indexPath animated:YES];

#pragma mark ZZAppCellDelegate 方法

- (void)appCellDidClickDownLoadBtn:(ZZAppCell *)cell

{

// 1.添加标签

UILabel *label = [[UILabel alloc] init];

label.text = [NSString stringWithFormat:@"成功下载%@",cell.app.name];

label.font = [UIFont systemFontOfSize:13.0f];

label.textAlignment = NSTextAlignmentCenter;

label.textColor = [UIColor whiteColor];

// 2.动画
