UITableViewController文件的位置

Question

I have multiple tableviews that have various static cells and everything is cool.

I would like to implement some functionality to a button that is in one of the cells in all of the tables, but I do not know where the header and implementation files for UITableViewController are located and or how to access them. Any ideas?

Answer 1

You can't directly manipulate UITableViewController . Besides, it is not a good idea to do it anyway. The best way to do it is subclassing it.

1. Command+N and create a new NSObject file
2. When prompted, name it whatever you like (eg MyTableViewController )
3. Click on MyTableViewController.h in left side pane, and change NSObject to UITableViewController .
4. Goto the XIB file or the Storyboard (whichever you are using) and change the class of your UITableViewController to MyTableViewController .
5. Give a number to the button's tag field (eg 1001).
6. Now, in your MyTableViewController.m class, get a hold of the cell ( cellAtIndexPath: ) and then get a hold of that button with tag ( [cell.contentView viewWithTag:] ).
