错误：将单元格插入节

Question

'NSInternalInconsistencyException'，原因：'尝试将第1行插入第0部分，但更新后第0部分只有1行'

-(void)actionAddMore:(UIButton *)sender{

[_tblTask beginUpdates];
[_tblTask insertRowsAtIndexPaths:@[[NSIndexPath indexPathForRow:1 inSection:0]] withRowAnimation:UITableViewRowAnimationAutomatic];
[_tblTask endUpdates];

}
