本文详细解析了UITableView在Swift中使用过程中遇到的cell加载问题，包括如何正确注册cell类或nib文件，以及未注册时可能引发的应用崩溃等问题。


non-forIndexPath: version returns nil in that case.


forIndexPath: version asserts (crashes) if you didn't register a class or nib for the identifier.


forIndexPath:  must register a class or nib file using the registerNib:forCellReuseIdentifier: or registerClass:forCellReuseIdentifier: method before calling this method.

也就是cell是存在的。当无cell 时是不可以用的


swift - UITableViewCell复用机制的使用步骤
RRJia的博客

前言：UITableViewCell的复用机制是指，只创建一定数量的cell，然后将它们储存起来，在滑动屏幕的过程中，循环重复使用这些cell。这样做既避免了储存cell时对内存的消耗，又避免了频繁创建和销毁cell时对性能的影响。 实现方法：自定义tableViewCell类、注册cell复用池、调用复用池中的cell 步骤一：创建Cell.swift文件，让该类继承TableViewCell，代码如下： import UIKit // MARK: - 自定义TableViewCell，以便使用

1.dequeueReusableCellWithIdentifier:可以注册cell，也可以用if判断创建cell。对于使用if判断时，如果缓存池中有可重用的cell时，不会执行if判断，如果缓存池没有可重用的cell，执行if中的方法，但是有可能会覆盖上storyboard中的cell样式。2.dequeueReusableCellWithIdentifier:  forIndexPath：...

在自定义cell的情况下，dequeueReusableCellWithIdentifier:方法获取的cell可能为空，需要代码判断，手动加载cell的xib文件。而dequeueReusableCellWithIdentifier: forIndexPath: 方法获取的cell不会为空。使用步骤为： 1.在tableView初始化时，向tableView注册重用identifier[_tab
