 -(void)viewWillAppear:(BOOL)animated  
{  
  [super viewWillAppear:animated];  
  NSLog(@"view will Appear");    
  [tableView reloadData];  
}

if still it is not calling then try to call through code , as per example [classobj viewWillAppear:NO];

The viewWillAppear and other related methods are called to the viewcontroller that are linked with the rootViewController of the mainWindow. So if you are using a view based application, the viewWillAppear method of the first view controller will work properly and others wont.

I think that the problem you are seeing is that viewWillAppear: is a method on a UIViewController, and not a method on UIView. viewWillAppear: is called on the view controller to indicate that the controller's view will become visible.

If you have added the code above to a class based on UIView, that code won't get called. You need to move that code to your view controller -or- you might achieve the result that you are looking for by implementing the didMoveToSuperview method in your UIView based class instead.

didMoveToSuperview will be called on your view when your view is added to another view using addSubview:.

Hi Here I did instead

[self.view addSubview:viewcontroller.view];

I Used this:

[self presentModalViewController:viewcontroller animated:YES];

and write this method now my problem is solved.

-(void)viewWillAppear:(BOOL)animated
{
    NSLog(@"==========view will appear");
}
