cell = [tableView dequeueReusableCellWithIdentifier:identifier]
无需注册,但需要在此语句下进行 alloc init 的创建

cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath]
需要注册,不需要进行 alloc 和 init  因为在forIndexPath:indexPath语句中,系统从 cell 的重用队列的集合中自动取出 cell.
注册方式:
1.代码注册 [tableView registerClass:<#(Class)#> forCellReuseIdentifier:<#(NSString *)#>]
[tableView registerNib:<#(UINib *)#> forCellReuseIdentifier:<#(NSString *)#>]
2.storyboard 注册cell  和 xib 注册cell
在 storyboard 中的 cell 属性的 identifier 中添加字符串,则系统会自动注册 cell
在 xib 中,cell 属性的 identifier 中添加字符串 后仍然需要代码执行注册,且 identifier 需要一致
