Calling view controller method from delegate class, having issues - iphone

Question

I am calling view controller method from delegate class, the method is called but uitableview declared in that method does not call it delegate methods and a buttons and view also alloc in that view but nothing is shown.
Explaining from begining:
On navigation controller needed a button and to be shown on all views. So, i took that in delegate this way.
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];
}
This is the view controller class:
-(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];
}
Now, nothing is displyed when this method is called, control goes through it but nothing happens, no delegates of table are called and neither other stuff works(button searchbar and uiview).
Please guide for the above. Thanks in advance.

Answer 1

Try to use of NSNotificationCenter like this
Register Notification in your ViewController.m
- (void)viewDidLoad
{
[[NSNotificationCenter defaultCenter] addObserver: self
selector: #selector(menu)
name: #"myMenuNotification"
object: nil];
}
And in your AppDelegate.m call that method using notification like
-(void)menu
{
[[NSNotificationCenter defaultCenter] postNotificationName:#"myMenuNotification" object:nil];
}

I don't know how you are using. But I have checked code with some modification. it is working fine.
Your modified code is:
In AppDelegate method.
- (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];
}
//In view Controller............
-(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];
}
