One way to do this is embedding Applescript in your Objective-C application. For example executing this apple script, sends Command + M to System Events application:

You can embed the script above in your Cocoa application with something like this:

//AppControler.h
#import 

@interface AppController : NSObject {
    NSAppleScript *key;
}
-(IBAction)sendkeys:(id)sender;
@end

//AppControler.m
#import "AppController.h"

@implementation AppController

-(IBAction)sendkeys:(id)sender
{
    NSAppleScript *key = [[NSAppleScript alloc] initWithSource:@"tell application "System Events" to keystroke "m" using {command down}"];
    [start executeAndReturnError:nil];
}

@end
