Can you access application delegate from within a UITableViewDataSource function?

Question

I\'m trying to figure out the SQLite functionality for the iPhone, and I\'m having some problems reading my database file from an overridden UITableViewDataSource function.

Answer 1

While I don't like sticking too much into my AppDelegate, I'll often need to access it to get to other singletons in my app, which makes the method call + cast a little cumbersome. So in most of my apps, I'll define a quick macro in my global header file.

Example follows:

#define MY_DELEGATE (AppDelegate*)[[UIApplication sharedApplication] delegate]

It's a lot easier to refer to MY_DELEGATE.
