NSInternalInconsistencyException tableView 行删除

Question

Swift 3.0 iOS 10.x

使用此代码尝试删除 table...

中的一行

override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if editingStyle == UITableViewCellEditingStyle.delete {
        print("DELETE \(indexPath)")
        self.tableView.deleteRows(at: [indexPath], with: UITableViewRowAnimation.automatic)


    }
}

这失败并显示错误消息？

2017-05-29 13:36:23.843228+0200[939:576777] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0.  The number of rows contained in an existing section after the update (9) must be equal to the number of rows contained in that section before the update (9), 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).'

只有这是样板代码，这听起来很公平吗？我只是点击红色按钮而已？

是的，这里有 3 行...在我崩溃的代码中有 9 行。

我在这里错过了什么？在这里打印出返回的indexPath，确实是错误的，但是等等我没有设置它。这个方法有吗？

您必须先删除数据数组中的行，然后才能在 tableView

中删除

override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if editingStyle == UITableViewCellEditingStyle.delete {
        print("DELETE \(indexPath)")
        yourArray.remove(at: indexPath.row) /* delete in data array */
        self.tableView.deleteRows(at: [indexPath], with: UITableViewRowAnimation.automatic)
    }
}
