presenting a view not working in iphone

问题

I am trying to navigate from one page to another on a button click in a facebook appliaction.
I am using

registerUser=[[RegisterPage alloc]initWithNibName:@"RegisterPage" bundle:nil];
[self presentModalViewController :registerUser animated:YES];

for presenting the next view after getting response from facebook.
But it is not showing the next view. It works fine in all other places where I used to present other views.

Anyone have idea about this issue?

回答1:

What exactly is 'self' here? Is it a viewcontroller? Or just a UIView? I think this'll only work if self is a viewcontroller or some subclass of it.

回答2:

My code to present a view controller is somewhat like yours (without a nib):

ViewController *controller = [[ViewController alloc] initWithNibName:nil bundle:nil];
[controller setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
[self presentModalViewController:controller animated:YES];
[controller release];

And to present a navigation controller it's like this (without a nib):

ViewController *controller = [[ViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navController = [[UINavigationController alloc]       initWithRootViewController:controller];
[navController setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
[self presentModalViewController:navController animated:YES];
[navController release];
[controller release];

Sometimes simply copying someones code helps.
