Delegate won't work - objective-c

Question

I have a simple delegate test, but for some reason it doesn't get called.
I want to call -(void)test from AppDelegate class via delegate.
/// AppDelegate.h
#import <Cocoa/Cocoa.h>
#protocol AppDelegateDelegate
#required
-(void)test;
#end
#interface AppDelegate : NSObject <NSApplicationDelegate> {
id<AppDelegateDelegate> _delegate;
}
#property(nonatomic, retain) id<AppDelegateDelegate> delegate;
#end
/// AppDelegate.m
#import "AppDelegate.h"
#implementation AppDelegate
#synthesize delegate = _delegate;
-(void)awakeFromNib {
[_delegate test];
}
#end
/// test.h
#import <Foundation/Foundation.h>
#import "AppDelegate.h"
#interface test : NSObject <AppDelegateDelegate>
-(void)test;
#end
/// test.m
#import "test.h"
#implementation test
-(void)test {
//this should be called from AppDelegate
NSLog(#"delegate test");
}
#end

You are calling the delegate test method as soon as the AppDelegate class is loaded and no other class has had a chance to set themselves as the delegate. You need to call the delegate method after another class has had a chance to set itself as the delegate.
Also your delegate property should be defined as:
#property (assign) IBOutlet id <AppDelegateDelegate> delegate;
