UIImagePickerController reloads view after its dismissed?

I create the picker:

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType =  UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
imagePicker.allowsEditing = NO;
[self presentModalViewController:imagePicker animated:YES];

and I handle the didFinishPickingMediaWithInfo:

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissModalViewControllerAnimated:YES];
[picker release];}

but this calls the viewDidLoad on self. This is not normal is it? Whats wrong?

I had some kind of that issue and I'd tried to set presentation "Over full screen" and it worked without reloading

I had a similar issue with this, I was displaying a popup during a long press gesture. It appeared as though the modal was not dismissed after the image was selected. However, the long press gesture event gets called several times, so a new popup was being displayed for every event. In my gesture handler I do something like this as to fix:

if (![imagePickerPopoverController isPopoverVisible]){
   //show pop-up etc
}

Your app probably received a memory warning, which caused all view controllers who are not displayed on screen to unload their views. This is quite normal while you are in the image picker because the camera needs a lot of memory. The moment you dismiss the image picker your view controller reloads its view.

As this is perfectly normal behavior, your app must deal with this situation correctly.
