4. UIPop over view programatically....

PopimagepickerViewController.h
                UIPopoverController *popoverController;
              UIPopoverController *popoverimagview;  // imagepicker popoverview

PopimagepickerViewController.m
        
     -(IBAction)popbtn_Click:(id)sender

{

UIViewController* popoverContent = [[UIViewController alloc] init];

UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0,230,180)];

popoverView.backgroundColor = [UIColor whiteColor];

popoverContent.view=popoverView;

popoverContent.contentSizeForViewInPopover = CGSizeMake(230, 180); // Set the popoverview Width and height

//create a popover controller

popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];

CGRect popoverRect = [self.view convertRect:[popbtn frame]

fromView:[popbtn superview]];

popoverRect.size.width = MIN(popoverRect.size.width, 100) ;

popoverRect.origin.x = popoverRect.origin.x;

[popoverController

presentPopoverFromRect:popoverRect

inView:self.view

permittedArrowDirections:UIPopoverArrowDirectionUp +

UIPopoverArrowDirectionLeft //pooverview down direction

animated:YES];

[popoverView release];

[popoverContent release];

}

Note: To create uiimagepicker for Ipad not showing normal imagepicker control animation like ipod.but it shows like popoverview.

-(void)select_btnclick:(id)sender

{

UIImagePickerController * picker = [[UIImagePickerController alloc] init];

picker.delegate = self;

if((UIButton *) sender == select_btn) {

picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

popoverimagview = [[UIPopoverController alloc] initWithContentViewController:picker];

[picker release];

[popoverimagview presentPopoverFromRect:CGRectMake(0.0, 0.0, 350, 350) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

} else {

picker.sourceType = UIImagePickerControllerSourceTypeCamera;

}

}

//dismissPopoverview

if (popoverimagview != nil)

{

[popoverimagview dismissPopoverAnimated:YES];

}
