呼叫视图控制器的方法，有问题

Question

我打电话从委托类视图控制器的方法，该方法被调用，但UITableView的在方法声明不把它委派方法和一个按钮和观点也ALLOC该观点，但没有显示。

从begining解释：

在导航控制器所需的按钮，并在所有视图中显示。所以，我以这种方式代表委托人。

UIButton *btnMenuOpen = [UIButton buttonWithType:UIButtonTypeCustom]; 
btnMenuOpen.frame = CGRectMake(0, 15, 40, 56); 
[btnMenuOpen setImage:[UIImage imageNamed:@"side_menu.png"] forState:UIControlStateNormal]; 
[btnMenuOpen addTarget:self action:@selector(menu) forControlEvents:UIControlEventTouchUpInside]; 
[self.window addSubview:btnMenuOpen]; 

-(void)menu 
{ 
ViewController *viewC = [[ViewController alloc]initWithNibName:@"ViewController" bundle:nil]; 
[viewC menu]; 
} 

这是视图控制器类：

-(void)menu 
{ 
NSLog(@"menu opened"); 

self.mMenuView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 240, 480)]; 
self.mMenuView.backgroundColor = [UIColor grayColor]; 
self.mMenuView.autoresizingMask = 0; 
[self.navigationController.view addSubview:self.mMenuView]; 

self.mSearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 16, 220, 44)]; 
self.mSearchBar.autoresizingMask = UIViewAutoresizingFlexibleWidth; 
self.mSearchBar.backgroundImage = [UIImage imageNamed:@"slide_tab_button.png"]; 
self.mSearchBar.delegate = self; 
[self.mMenuView addSubview:self.mSearchBar]; 

UIButton *btnMenuClose = [UIButton buttonWithType:UIButtonTypeCustom]; 
btnMenuClose.frame = CGRectMake(215, 19, 40, 44); 
[btnMenuClose setImage:[UIImage imageNamed:@"side_menu.png"] forState:UIControlStateNormal]; 
[btnMenuClose addTarget:self action:@selector(menu_close) forControlEvents:UIControlEventTouchUpInside]; 
[self.mMenuView addSubview:btnMenuClose]; 

self.mMenuTableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 61, 
                    240, 420) style:UITableViewStylePlain]; 
self.mMenuTableView.delegate = self; 
self.mMenuTableView.dataSource = self; 
[self.mMenuView addSubview:self.mMenuTableView]; 

[self.mMenuTableView reloadData]; 

} 

现在，当这种方法被称为什么将会持续显示，控制经过，但没有任何反应，没有表的代表们呼吁，并没有其他的东西作品（按钮搜索栏和uiview）。

请指导的上方。提前致谢。

尝试使用NSNotificationCenter这样

注册通知你ViewController.m

- (void)viewDidLoad 
{ 
    [[NSNotificationCenter defaultCenter] addObserver: self 
              selector: @selector(menu) 
               name: @"myMenuNotification" 
               object: nil]; 
} 

而在你AppDelegate.m调用使用通知方法一样

-(void)menu 
{ 
    [[NSNotificationCenter defaultCenter] postNotificationName:@"myMenuNotification" object:nil]; 
}

我不不知道你是如何使用的。但我已经通过一些修改检查了代码。它工作正常。 你的修改后的代码是：

在AppDelegate中方法。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
    // Override point for customization after application launch. 
    self.viewController = [[sampleViewController alloc] initWithNibName:@"sampleViewController" bundle:nil]; 
    self.navController=[[UINavigationController alloc] initWithRootViewController:self.viewController]; 

    self.window.rootViewController = self.navController; 
    [self.window makeKeyAndVisible]; 

    UIButton *btnMenuOpen = [UIButton buttonWithType:UIButtonTypeCustom]; 
    btnMenuOpen.frame = CGRectMake(0, 15, 40, 56); 
    [btnMenuOpen setImage:[UIImage imageNamed:@"5.jpg"] forState:UIControlStateNormal]; 
    [btnMenuOpen addTarget:self action:@selector(menu) forControlEvents:UIControlEventTouchUpInside]; 
    [self.window addSubview:btnMenuOpen]; 

    [self menu]; 
    return YES; 
} 

-(void)menu 
{ 
    [self.viewController menu]; 
} 

//在视图控制器............

-(void)menu 
{ 
    NSLog(@"menu opened"); 

    UIView *mMenuView; 
    UISearchBar *mSearchBar; 
    UITableView *mMenuTableView; 

    mMenuView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 240, 480)]; 
    mMenuView.backgroundColor = [UIColor grayColor]; 
    mMenuView.autoresizingMask = 0; 
    [self.navigationController.view addSubview:mMenuView]; 

    mSearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 16, 220, 44)]; 
    mSearchBar.autoresizingMask = UIViewAutoresizingFlexibleWidth; 
    mSearchBar.backgroundImage = [UIImage imageNamed:@"5.jpg"]; 
// mSearchBar.delegate = self; 
    [mMenuView addSubview:mSearchBar]; 

    UIButton *btnMenuClose = [UIButton buttonWithType:UIButtonTypeCustom]; 
    btnMenuClose.frame = CGRectMake(215, 19, 40, 44); 
    [btnMenuClose setImage:[UIImage imageNamed:@"side_menu.png"] forState:UIControlStateNormal]; 
    [btnMenuClose addTarget:self action:@selector(menu_close) forControlEvents:UIControlEventTouchUpInside]; 
    [mMenuView addSubview:btnMenuClose]; 

    mMenuTableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 61, 240, 420) style:UITableViewStylePlain]; 
// mMenuTableView.delegate = self; 
// mMenuTableView.dataSource = self; 
    [mMenuTableView setBackgroundColor:[UIColor blueColor]]; 
    [mMenuView addSubview:mMenuTableView]; 

    [mMenuTableView reloadData]; 
}
