Dear all, there is a thing i can’t understand. In my class I have an NSMutableArray as a instance variable and a property. With the init method the array will be created with alloc / init. When my tableView has rows an information for each row will be added as object to my array. Then I have a

C callbacks with NSNotificationCenter?

As a C programmer I'm trying to avoid Objective C whenever and wherever possible. The good thing is that I can do most interaction with Cocoa from normal C functions. I only had to write very few classes. Most of the Cocoa stuff can be done from normal C functions just fine. Now I'd like to subs
