iOS开发bug消灭之：Invalid update: invalid number of rows in section 0.

Invalid update: invalid number of rows in section 0.

swift版本：3.0

Xcode版本：8.0

错误全文：

Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (8) must be equal to the number of rows contained in that section before the update (8), 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).

错误原因：删除TableView Cell的时候没有删除对应的数据源

错误源码：

let deleteAction = UITableViewRowAction(style: .default, title: "删除", handler: {(action,indexPath) -> Void in
let realm = try! Realm()
self.tableView.deleteRows(at: [indexPath], with: .fade)
})

修正源码：

let deleteAction = UITableViewRowAction(style: .default, title: "删除", handler: {(action,indexPath) -> Void in
//移除数据源
let realm = try! Realm()
try! realm.write {
realm.delete(self.employees[indexPath.row])
}
self.tableView.deleteRows(at: [indexPath], with: .fade)
})

注意事项：数据源要根据实际情况加以删除
