Automatically convert comment to #pragma mark

I have long liked to visually segment Protocol implementation code using the following:

// UIApplicationDelegate ===========================================================================
- (BOOL) application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)options {

However, the #pragma mark feature in Xcode is really quite useful. I also like the ability to add dividing lines. But this means my code now looks like:

// UIApplicationDelegate ===========================================================================
#pragma mark -
#pragma mark UIApplicationDelegate

- (BOOL) application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)options {

Which is becoming quite unwieldy. I really like the nice (normally) green line marked with the protocol embedded into the code itself, but I also like the pragma mark utility.

Is there anyway using preprocessor #define or other such commands to automatically convert the first into the 2nd?

Clang / Xcode also recognizes // MARK: for the same purpose as #pragma mark. (Also, this is the only style in Swift, since that language doesn't have a preprocessor.) So if you like green, you could do:

// MARK: - UIApplicationDelegate
// ========================

If you're looking for a way to automatically convert all uses of your previous notation to // MARK or #pragma, I'd recommend a good regex find/replace utility, of which there are too many to list here.

You can generate a #pragma from a macro, but the text editor won't see it unless it does macro expansion.

The _Pragma "operator" is defined to have the same effect as a #pragma directive.

#define PRAGMA_STR( TEXT ) _Pragma( # TEXT )
#define INDEX_MARK( NAME ) _Pragma("mark -") PRAGMA_STR(mark NAME)

It won't work within a comment, but you could do something like

INDEX_MARK( UIApplicationDelegate ) // =======================================

… if the editor looked at macros, which it probably doesn't.
