Ios InsertRowsAtIndexPaths，在[\u mainTableView endUpdates]处中断，但如果删除BeginUpdate和endUpdates，将在SDAutoLayout中中断

[UIView animateWithDuration:0.2f动画：^{

    NSMutableArray *indexPaths = [[NSMutableArray alloc] init] ;
    [_dataArray addObject:@"loading"];
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
    [indexPaths addObject: indexPath];
    [_mainTableView beginUpdates];
    [_mainTableView insertRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationNone];
    [_mainTableView endUpdates];
    
} completion:^(BOOL finished) {
  //  [_mainTableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:_dataArray.count - 1 inSection:0] atScrollPosition:UITableViewScrollPositionMiddle animated:YES];
}];

将打断sdautolayout:UITableView+SDAutoTableViewCellHeight.h-（void）sd_InsertRowsAndExpaths:（NSArray*）带RowAnimation的indexPaths:（UITableViewRowAnimation）animation{[self.cellAutoHeightManager insertNewDataAtIndexPaths:indexPaths]；[self-sd_insertRowsAtIndexPaths:indexPaths with row animation:animation]；}将在sdautolayout:UITableView+SDAutoTableViewCellHeight.h-（void）sd_insertRowsAtIndexPaths:（NSArray*）indexPaths with row animation:（uitableviewanimation）动画{[self.cellAutoHeightManager InsertNewDataAtIndexPath:IndexPath]；[self-sd_insertRowsAtIndexPaths:IndexPath with RowAnimation:animation]；}
