iphone - 自定义 View Controller 委托(delegate)不起作用

Question

我的自定义委托(delegate)有问题，不知道为什么不起作用。我想将委托(delegate)传递到主视图，以便在添加新记录后它会自动推送到详细 View 。

不确定我错过了什么。我正在做与 Storyboard和 iOS 5 的所有链接。

addnote.h

#import <UIKit/UIKit.h>
#import "memoView.h"

@protocol addNoteDelegate;
@interface addNote : UIViewController
{
    IBOutlet UITextField *memoNameTextField;
    IBOutlet UITextField *memoCommentsTextField;
    id <addNoteDelegate> delegate;
}

@property (nonatomic,assign) id <addNoteDelegate> delegate;


- (IBAction)done:(id)sender;
- (IBAction)cancel:(id)sender;
@end

@protocol addNoteDelegate <NSObject>
-(void)addNoteDidFinish:(addNote *)controller;
-(void)addNoteDidCancel:(addNote *)controller;
@end

addnote.m

-(IBAction)add:(id)sender
{   
   [[self delegate] addNoteDidFinish:self];
}

mainview.h

#import <UIKit/UIKit.h>
#import "addNote.h"

@interface mainView : UITableViewController<NSFetchedResultsControllerDelegate, addNoteDelegate>
{
}

@property (nonatomic, retain) NSArray *memoInfo;
@property (nonatomic, retain) NSFetchedResultsController *fetchedResultsController;
@property (nonatomic, retain) NSManagedObjectContext *ObjectContext;

-(IBAction)backToMain:(id)sender;
- (IBAction)addNote:(id)sender;
@end

mainView.m

-(IBAction)addNote:(id)sender
{
    addNote *addingNote = [[addNote alloc] init];
    addingNote.delegate = self;
    [self performSegueWithIdentifier:@"addNote" sender:self];
}

- (void)addNoteDidFinish:(addNote *)controller{
//PUSH TO NEXT VIEW

    [[self navigationController] dismissModalViewControllerAnimated:YES];
}

 @protocol addNoteDelegate <NSObject>
-(void)addNoteDidFinish:(addNote *)controller;
-(void)addNoteDidCancel:(addNote *)controller;
@end

@interface addNote : UIViewController
{
    IBOutlet UITextField *memoNameTextField;
    IBOutlet UITextField *memoCommentsTextField;
    id <addNoteDelegate> delegate;
}

@property (nonatomic,assign) id <addNoteDelegate> delegate;


- (IBAction)done:(id)sender;
- (IBAction)cancel:(id)sender;
@end

和:

[self dismissModalViewControllerAnimated:YES];

不是:

[[self navigationController] dismissModalViewControllerAnimated:YES];
