How to take picture from Camera & saved in Photo Gallery by programmatically?

Question

In iPhone Apps, I want to take pictures from Camera & save into Photo Gallery by programmatically. Is it possible in iPhone Simulator? so please tell me any link or materials you have.

Thanks in advance

Taking pictures from Camera is not possible in Simulator, you have to use device to test your code. — Mobile Developer iOS Android, Jul 25 '11 at 07:32

You would use uiimagepickercontroller for this purpose. First of all, import the MobileCoreServices.framework. Then pull up the camera:

if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
        NSArray *media = [UIImagePickerController
                          availableMediaTypesForSourceType: UIImagePickerControllerSourceTypeCamera];

        if ([media containsObject:(NSString*)kUTTypeImage] == YES) {
            UIImagePickerController *picker = [[UIImagePickerController alloc] init];
            picker.sourceType = UIImagePickerControllerSourceTypeCamera;
            //picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
            [picker setMediaTypes:[NSArray arrayWithObject:(NSString *)kUTTypeImage]];

            picker.delegate = self;
            [self presentModalViewController:picker animated:YES];
            //[picker release];

        }
        else {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Unsupported!"
                                                            message:@"Camera does not support photo capturing."
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK"
                                                  otherButtonTitles:nil];
            [alert show];
            [alert release];
        }

    }
    else {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Unavailable!"
                                                        message:@"This device does not have a camera."
                                                       delegate:nil
                                              cancelButtonTitle:@"OK"
                                              otherButtonTitles:nil];
        [alert show];
        [alert release];
    }

Then, save the photo by implementing the uiimagepickercontrollerdelegate and a save function:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    NSLog(@"Media Info: %@", info);
    NSString *mediaType = [info valueForKey:UIImagePickerControllerMediaType];

    if([mediaType isEqualToString:(NSString*)kUTTypeImage]) {
        UIImage *photoTaken = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

        //Save Photo to library only if it wasnt already saved i.e. its just been taken
        if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
            UIImageWriteToSavedPhotosAlbum(photoTaken, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
        }


    }

    [picker dismissModalViewControllerAnimated:YES];
    [picker release];
}

- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo {
    UIAlertView *alert;
    //NSLog(@"Image:%@", image);
    if (error) {
        alert = [[UIAlertView alloc] initWithTitle:@"Error!"
                                           message:[error localizedDescription]
                                          delegate:nil
                                 cancelButtonTitle:@"OK"
                                 otherButtonTitles:nil];
        [alert show];
        [alert release];
    }

}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
    [picker dismissModalViewControllerAnimated:YES];
}

I do hope you realize that the simulator does not have a camera..... So I guess thats not possible. You can definitely use a device.... You can make use of UIImagePickerController for capturing images.

There are 3 prerequesites needed to take a picture programmatically:

The device needs to have a camera check by

 if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])

Camera controls need to be hidden (picker is a UIImagePickerController)
```
picker.showsCameraControls = NO;
```
use the takePicture from UIImagePickerController

[picker takePicture];

Side note because it did bug me for a few minutes, the takePicture method also dismisses the view.
