1. 創(chuàng)建屬性 dataSource

@property (nonatomic, strong) NSMutableArray *dataSource;

2.懶加載并初始化 數(shù)據(jù)源

  - (NSMutableArray *)dataSource
 {
     if (_dataSource == nil) {
         _dataSource = [NSMutableArray array];
     }
     return _dataSource;
 }

3.請(qǐng)求省略 獲取到array數(shù)據(jù)插入

  //在第loc(loc可為0)個(gè)元素處插入長度為len的一組對(duì)象.當(dāng)loc == 0時(shí),表示將這組對(duì)象插入到原數(shù)組的最前面.
  [self.dataSource insertObjects:array atIndexes:[NSIndexSet indexSetWithIndexesInRange:NSMakeRange(0, array.count)]];

4.cell展示 使第array.count - 1cell顯示在屏幕頂部 動(dòng)畫為NO

  NSIndexPath *scrollIndexPath = [NSIndexPath indexPathForRow:array.count - 1 inSection:0];
   [self.tableView scrollToRowAtIndexPath:scrollIndexPath        atScrollPosition:UITableViewScrollPositionTop animated:NO];
