}
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage : (UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
imageView.image = image;
[picker dismissModalViewControllerAnimated:YES];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *) picker
{
[picker dismissModalViewControllerAnimated:YES];
}

Answer 1

On iPad you need to show it inside a UIPopoverController, not present it modally.

Answer 2

You can display the UIImagePicker as a modalView in iPhone. But in iPad you need to use UIPopover as a container for displaying the imagePicker.
Re-write your code like:
-(IBAction)selectExitingPicture
{
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
{
UIImagePickerController *picker= [[UIImagePickerController alloc]init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
self.popover = [[UIPopoverController alloc]
initWithContentViewController:picker];
popover.delegate = self;
[self.popover presentPopoverFromRect:CGRectMake(0,0,170,250)
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
else
{
[self presentModalViewController:picker animated:YES];
}
[picker release];
}
In your #interface add the necessary protocols and necessary instances
#interface yourController: UIViewController
<UIImagePickerControllerDelegate,
UINavigationControllerDelegate, UIPopoverControllerDelegate>
{
UIPopoverController *popover;
}
#property (nonatomic, strong) UIPopoverController *popover;
#end
It'll work on both iPad and iPhone.

Answer 3

You can try this:
Change the CGRectMake for custom popover and CGSizeMake for content size.
- (IBAction)imageFromAlbum:(id)sender
{
imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
// es iPad
if ([[UIDevice currentDevice]userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
//Averiguar si está en portrait o landscape
UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
//PORTRAIT
if(orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
{
[self cerrarTeclado];
self.popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
self.popover.delegate = self;
[self.popover presentPopoverFromRect:CGRectMake(600, 400, 311, 350) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:NO];
[self.popover setPopoverContentSize:CGSizeMake(330, 515)];
}
//LANDSCAPE
if (orientation == UIInterfaceOrientationLandscapeRight || orientation == UIInterfaceOrientationLandscapeLeft)
{
self.popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
self.popover.delegate = self;
[self.popover presentPopoverFromRect:CGRectMake(850, 400, 311, 350) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:NO];
[self.popover setPopoverContentSize:CGSizeMake(330, 515)];
}
} else {
// no es iPad
[self presentViewController:imagePicker animated:YES completion:nil];
}
}
