Question

I want to use a UIPopoverController in my application and was trying this example. The problem is that the view and the controller in that example are created from code.

   UIViewController* popoverContent = [[UIViewController alloc]
                  init];
   UIView* popoverView = [[UIView alloc]
                  initWithFrame:CGRectMake(0, 0, 200, 300)];
   popoverView.backgroundColor = [UIColor greenColor];
   popoverContent.view = popoverView;

I want to use an existing controller with it’s xib file for the popup. How do I link the popup to an existing controller? And do I need to create the controller’s view in some special way for it to match the dimension of the popup?

Answer 1

If you want to use an existing xib, just initialize your viewController using the nitWithNibName:bundle: method. When you init using the xib your viewController’s view hierarchy will be instantiated for you.

UIViewController* popoverContent = [[UIViewController alloc] initWithNibName:@"yourXibName" bundle:nil];

Don’t worry about sizing the view when you initialize – the view gets resized in the example code you cite anyway on the next line when the property contentSizeForViewInPopover is set.
