无法分配self.delegate它会产生无法识别的选择器

Question

我是一个新的iOS和我在落实麻烦@protocol很抱歉,如果你认为这是一件容易的事情..

我一直在四处寻找stackoverflow.com,该网也尝试叔叔谷歌了一会儿,我决定问这里...

其主要思想是调用从TopViewController一个MyViewController,做翻转动画我创建协议开始..

    // This is my Delegate header
    // MyViewController.h

    @protocol MyViewControllerlDelegate

    - (void) myViewControllerDidFinish;

    @end

    @interface MyViewController : UIViewController 
    {
     id <MyViewControllerlDelegate> delegate;
    }

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

    - (IBAction) done;

    @end

以下是实施:

    // MyViewController.m

    #import "MyViewController.h"

    @implementation MyViewController

    @synthesize delegate;

    // Another Code above

    - (IBAction)done 
    {
     [self.delegate myViewControllerDidFinish];
    }

    // Another Code Below

    @end

我使用上面的对象从下面的另一个视图调用并在其中添加翻转过渡:

// TopViewController.h

#import "MyViewController.h"

@class MapScrollView;

@interface TopViewController : UIViewController <UIScrollViewDelegate,MyViewControllerlDelegate> 
{
    UIScrollView *topScrollView;
    UIButton *infoButton;
}

@end

TopViewController.h实现//TopViewController.m

#import "TopViewController.h"
#import "CustomScrollView.h"
#import <QuartzCore/QuartzCore.h>

- (void)loadView 
{    
    // Step 1: make the outer paging scroll view
    CGRect topScrollViewRect = [[UIScreen mainScreen] bounds];
    topScrollView = [[UIScrollView alloc] initWithFrame:topScrollViewRect];
    topScrollView.pagingEnabled = YES;
    topScrollView.backgroundColor = [UIColor blackColor];
    topScrollView.showsVerticalScrollIndicator = NO;
    topScrollView.showsHorizontalScrollIndicator = NO;
    topScrollView.contentSize = CGSizeMake(topScrollViewRecte.size.width,
                                              topScrollViewRecte.size.height);
    topScrollView.delegate = self;
    self.view = pagingScrollView;

    CustomScrollView *sView = [[[MapScrollView alloc] init] autorelease];

    sView.frame = [[UIScreen mainScreen] bounds];

    [sView displayTiledMap];

    [pagingScrollView addSubview:sView];

    // add Info Button
    UIButton *button = [UIButton buttonWithType:UIButtonTypeInfoDark];
    [button addTarget:self action:@selector(infoIsTouch:)   forControlEvents:UIControlEventTouchDown];
    button.frame = CGRectMake(282.0, 440.0, 18.0, 19.0);
    [self.view addSubview:button];
}

-(void)infoIsTouch:(id)sender
{
 MyViewController *myView = 
 [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:[NSBundle mainBundle]];
 myView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
        //
        //Here where the code is crash 
        //
 [myView setDelegate:self];
        //
        //Code from here to below is not run...
        //
 [self presentModalViewController:myView animated:YES];
 [myView release];
}

- (void) myViewControllerDidFinish
{
 [self dismissModalViewControllerAnimated:YES];
}

etc... 

@end

下面的代码产生以下编译错误..

2010-12-06 01:09:07.946 MyViewDelegatePractice[9473:207] -[TopViewController setDelegate:]: unrecognized selector sent to instance 0x5f30fb0
2010-12-06 01:09:07.949 MyViewDelegatePractice[9473:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[TopViewController setDelegate:]: unrecognized selector sent to instance 0x5f30fb0'
*** Call stack at first throw:

    // Cuts... 
)
terminate called after throwing an instance of 'NSException'

当我按下infoButton其称之为引发这些错误 - (空)infoIsTouch:(ID)发送方法,然后停在[MyView的setDelegate:自我]行..任何人都可以给我一个提示哪里是我的错误是什么？

注意:如果你厌恶我的英语..随意评论也可以..但在那之前..我很抱歉我尽我所能..
