Not sure if the above is even my question as I am basically new to using objective-c and iOS and not sure if that's the right wording but anyway...
不确定上面是否甚至是我的问题，因为我基本上不熟悉使用objective-c和iOS而且不确定这是否是正确的措辞但无论如何......
Basically I have completed this tutorial https://www.youtube.com/watch?v=ITUI7fukRO8 for using a tableView with an array of data.
基本上我已经完成了本教程https://www.youtube.com/watch?v=ITUI7fukRO8，用于使用带有数据数组的tableView。
The substance of the program consists of a navcontroller, tableviewController and a viewController for the extra detail of the table data.
该程序的实质包括一个navcontroller，tableviewController和一个viewController，用于表数据的额外细节。
Currently I have a button (from another viewcontroller) that is linking to my tableView. How would I go about setting up and IF statement in regards to the button pressed (-as I need to link other buttons from other controllers) so that if a specific button is pressed, the array that is displayed in the tableView is different.
目前我有一个链接（从另一个viewcontroller）链接到我的tableView。我如何设置关于按下按钮的设置和IF语句（ - 我需要链接来自其他控制器的其他按钮），这样如果按下特定按钮，则tableView中显示的数组是不同的。
I'm currently thinking of doing a bunch of if, then, else statements and just manually changing the detail of the arrays.
我正在考虑做一堆if，then，else语句，只是手动改变数组的细节。
Is this the way to go?? Or should I just set up another table view for each of my buttons.
这是要走的路？或者我应该为每个按钮设置另一个表视图。
I have a set of .h and .m for the tableCell, tableCellController, and the ViewController.
我有一组.h和.m用于tableCell，tableCellController和ViewController。
That probably didn't make a whole lot of sense but if you somewhat understand help would be appreciated. Cheers
这可能没有多大意义，但如果你有点理解帮助将不胜感激。干杯
Edit: As you can see my code is pretty 'all over the shop' at the moment. I haven't included the Cell View controllers as I don't think they have that much relevance with what I want to do at this stage.The buttonviewcontroller is just a normal UIViewController and both buttons are linked as 'Button1'class in the storyboard. They have been given tags 0 and 1 which I believe is in under the 'view' subheading in the storyboard. Please alert me if this is wrong and I am missing something really obvious but that was the only place I could find 'tag'. ARRRG Objective-c is frustrating when you don't the language at all./ Updated Code as 21/03.
编辑：你可以看到我的代码目前非常“遍布整个商店”。我没有包含Cell View控制器，因为我认为它们与我在这个阶段想要做的事情没那么相关.buttonviewcontroller只是一个普通的UIViewController，两个按钮在故事板中被链接为'Button1'class 。他们已经给出了标签0和1，我认为它们位于故事板中的“视图”子标题下。请提醒我，如果这是错误的，我错过了一些非常明显的东西，但那是我唯一能找到'标签'的地方。 ARRRG Objective-c在您根本不使用该语言时会感到沮丧./更新代码为21/03。

Do a CTRL - drag in Storyboard to create a IBAction for the button.
执行CTRL - 在Storyboard中拖动以创建按钮的IBAction。
In the IBAction method, get the data you want for your data arrays (Images, Title, Description ref the tutorial you linked). Then call:
在IBAction方法中，获取数据数组所需的数据（图像，标题，描述参考链接的教程）。然后打电话：
[tableview reloadData]
This will repopulate the tableview.
这将重新填充tableview。
