ios delegate doesn't fire - ios

Question

i try a simple Delegate but the method won't fire. Here is my code:
The view with the protocol and a button which should trigger the delegate:
ViewController.h
#import <UIKit/UIKit.h>
#protocol InitStackDelegate <NSObject>
#required
-(void)initstack:(NSInteger)amount;
#end
#interface ViewController : UIViewController{
IBOutlet UITextField *amountTextField;
__unsafe_unretained id<InitStackDelegate> delegate;
}
- (IBAction)init:(id)sender;
#property (nonatomic,assign)id delegate;
#end
ViewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize delegate;
- (IBAction)init:(id)sender {
//send the delegate
[delegate initstack:[amountTextField.text intValue]];
}
AppDelegate.h
#import <UIKit/UIKit.h>
#import "ViewController.h"
#interface AppDelegate : UIResponder <UIApplicationDelegate,InitStackDelegate> {
}
#property (strong, nonatomic) UIWindow *window;
#property (strong,nonatomic) ViewController *myView;
#end
AppDelegate.m
#import "AppDelegate.h"
#implementation AppDelegate
#synthesize window;
#synthesize myView;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
// Override point for customization after application launch.
//..... push second controller into navigation stack
myView.delegate = self;
return YES;
}
...
#pragma mark Delegate Method
-(void)initstack:(NSInteger)amount{
NSInteger test;
}
#end
When i hit the button i get to (IBAction) init but then the delegate do nothing. I set a breakpoint in AppDelegate.m but it is never reached. Any help?
thx

In you App Delegate, when you set myView.delegate=self myView doesn't actually point to anything!
You need to set myView to point to your ViewController.
Use this in didFinishLaunchingWithOptions
myView = (ViewController *)self.window.rootViewController;
myView.delegate = self;
