Контроллер UIPickerview не может выбрать изображение и использовать его в xcode4.2, но хорошо работает на xcode 3.2

У меня есть UIImagePickerController, этот код, приведенный ниже, прекрасно работает на XCODE 3.2, но приложение зависает при соблюдении XCODE 4.2

Также, но иногда он запускается на некоторых других машинах один раз.

Может кто-нибудь сказать мне причину этого? Большое спасибо.

    UIActionSheet *popupQuery = [[UIActionSheet alloc] initWithTitle:@"Add Photo" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Take Photo" otherButtonTitles:@"Choose From Library", nil];
    popupQuery.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
    [popupQuery showInView:self.view];
    [popupQuery release];
}

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0) {

        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
        [self presentModalViewController:picker animated:YES];
        [picker release];



    } else if (buttonIndex == 1) {
