删除cell时遇到的错误Assertion failure in

报错信息如下

原因是没有先remove数据就调用deleteRowsAtIndexPaths方法

[self deleteRowsAtIndexPaths:@[delectIndexPath] withRowAnimation:UITableViewRowAnimationFade];
[self.dataArray removeObjectAtIndex:indexPath.row];

所以报错.
修改后代码为

 NSIndexPath *delectIndexPath =[NSIndexPath indexPathForRow:indexPath.row inSection:0];
[self deleteRowsAtIndexPaths:@[delectIndexPath] withRowAnimation:UITableViewRowAnimationFade];
[self.dataArray removeObjectAtIndex:indexPath.row];
