#pragma mark 第二个协议方法,主要用来显示数据
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

//static 特点 1.仅仅初始化一次2.假设没有初始值,默认是0 3.直到程序结束,才会消失
//当cell显示结束之后,会把cell统一放到重用池中,等须要cell显示了,先从重用池中找,看有没有闲置cell,假设有就用闲置的cell,假设没有在创建
//cell的重用目的是为了节约成本,用有限的cell把全部数据都显示出来
//给重用池设置一个重用的标志,依据这个标志找到相应的重用池
//tableview通过重用标志在重用池中寻找cell,假设有闲置的cell,cell会保存一个有效地cell对象地址,假设没有,cell里则为nil,空
