Open camera view upon app Startup (iOS6)

问题

what im trying to do is to have the app open up with the camera as the first screen. It isn't working and i don't know what im missing. If anyone can fill me in that would be wonderful... Thanks.

    - (void)viewDidLoad
{


[super viewDidLoad];
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];

if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
    [imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
}
else
{
    [imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
}


}

Try like that. Hope it helps you:

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

imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;

imagePicker.delegate = self;

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