Question

-(void)viewDidLoad
{
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
   {
      imagePicker = [[UIImagePickerController alloc] init];
      imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
      imagePicker.showsCameraControls = NO;
      [self.view addSubview:imagePicker.view];
      }
      else
      {
      // UIAlertView…
      }
}

    -(void)viewDidAppear:(BOOL)animated
    {
        [super viewDidAppear:animated];
        imagePicker.delegate = self;
        [self presentViewController:imagePicker animated:NO completion:NO];
    }

I want to put out an alert when you do not have a camera.
IPhone app launch and move in this code.
But, Crash (This Error >

return UIApplicationMain(argc, argv, nil, NSStringFromClass([CameraAppDelegate class])); > Thread 1: signal SIGABRT) when run in a simulator.

Why is this?

Answer 1

use this code and add UIImagePickerControllerDelegate delegate in .h file

 if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])  
    {
       UIImagePickerController* picker = [[UIImagePickerController alloc] init];
       picker.sourceType = UIImagePickerControllerSourceTypeCamera;
       picker.delegate = self;
      picker.wantsFullScreenLayout = YES;
      [self presentModalViewController:picker animated:YES];
    }
    else
    {
        UIAlertView *altnot=[[UIAlertView alloc]initWithTitle:@"Camera Not Available" message:@"Camera Not Available" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
        altnot.tag=103;
        [altnot show];
        [altnot release];

    }
