ios - NSInternalInconsistencyException 修复

Question

更新方法:

override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if editingStyle == .delete {
        initialData[indexPath.section].remove(at: indexPath.row)

        tableView.deleteRows(at: [indexPath], with: .fade)

    } else {

    }
}

错误:

reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (2) must be equal to the number of rows contained in that section before the update (2), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).

我该如何解决这个问题？

Answer 1

非常仔细地阅读您的控制台告诉您的内容。

您的数据源提示说，在您使用 removeAtIndexPaths() 删除一行后，它没有预期的行数。

确保您在删除/添加的内容以及相应更改的数据源中保持完整性。此外，请确保在主队列上进行这些更改。

祝你好运! :)
