Shift to UIPopoverPresentationController

Question

I want to create the same popover for my iPhone app with size GGrect of (320 100.0). Here is my old code:

View * pk1 = [[View alloc] init];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:pk1];
pop = [[UIPopoverController alloc] initWithContentViewController:nav];
[pop setDelegate:self];
[pop presentPopoverFromRect:[self btnsavepart].frame inView:[self view] permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[nav release];

I using this codes but its doesn't change

nav.preferredContentSize = CGSizeMake(320, 100);

I can not change UIpopovercontriller with UIPopoverPresentationController.

How do I specify GGrect of (320 100.0)?

i thinks i can change only on horizontally but how can i do.

  View *viewController = [[[View alloc] init] autorelease];
    UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:viewController] autorelease];


    navController.modalPresentationStyle = UIModalPresentationPopover;
    navController.popoverPresentationController.permittedArrowDirections = UIPopoverArrowDirectionUp;
    navController.popoverPresentationController.sourceRect = btnsavepart.bounds;
    navController.popoverPresentationController.sourceView = btnsavepart;
    navController.popoverPresentationController.delegate = self;

    [self presentViewController:navController animated:YES completion:nil];

i want the UIPopoverPresentationController not FullScreen form in iPhone

i adding this codes but i give the FullScreen view

- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller

{

return NO;

}

I work with Xamarin but its same thing , to specify size of the popover in which you want to display your UIViewController, in the properties of your UIVIewController you have the PreferredContentSize property. There you specify the size.

I saw it somewhere here but forgot where.
