I need to call a method and pass an object from my custom UITableViewClass implementation to my UITableViewController class. I realize creating an instance of the tableViewController in the custom tableViewCell and calling tableViewController's method is a bad practice.
What is the proper way of doing this?
Two magical concepts in Objective-C are Delegation and Notifications.
Delegation allows you to have your controller hook into a weak object referenced in the cell, which avoids a retain cycle, while still allowing you to send messages to it.
Notifications allow your Cell to broadcast a general notification to any classes that are active and listening for it.
Pick one, and whichever is easiest, stick with it. The two are basically equal in this situation.
