Why am I getting all of these compilation errors in my iOS app? [closed]

by

Whoah. You need to take two steps back and review the basic architecture of iOS applications.

If the code you claim to be in main.m really is in main.m, then your app is not structured correctly at all. In fact, in just about all iOS applications, you should never touch the main.m file at all. And those are obviously instance method implementations which means they should be in a class’s @implementation.
