how to prevent saving picture from camera roll again - iphone

Question

May be this question is too easy or I did not know how easy it will be.
I have an actionsheet to allow the user to choose how if they want to take a photo or select from camera.
The app will save user taken photo regardless is selected from camera roll or taken from camera. Am I missing something?
Thanks for reading my question.
#pragma mark - photo select
-(IBAction)showCameraAction:(id)sender
{
if(![UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera])
{
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#""
delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil
otherButtonTitles:#"Choose Photo From Library", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleAutomatic;
actionSheet.tag =1;
[actionSheet showInView:[self.view superview]];
}
else
{
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#""
delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil
otherButtonTitles:#"Take Photo With Camera", #"Choose Photo From Library", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleAutomatic;
actionSheet.tag =1;
[actionSheet showInView:[self.view superview]];
}
}

//NSArray *mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:sourceType];
if ([UIImagePickerController isSourceTypeAvailable:sourceType])

}
else
{

[alert show];
}

//answer fix, to prevent saving picture from cameraroll again.

Try this code.. Its working properly from my side.
- (IBAction) uploadPhoto:(id)sender
{
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#""
delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil
otherButtonTitles:#"Use Photo from Library", #"Take Photo with Camera", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
actionSheetAction = ActionSheetToSelectTypeOfSource;
[actionSheet showInView:self.view];
[actionSheet release];
}
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
UIImagePickerControllerSourceType sourceType;
if (buttonIndex == 0) {
sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
} else if(buttonIndex == 1) {
sourceType = UIImagePickerControllerSourceTypeCamera;
}else {
// Cancel
break;
}
if([UIImagePickerController isSourceTypeAvailable:sourceType]) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = sourceType;
picker.delegate = self;
if (sourceType == UIImagePickerControllerSourceTypeCamera) {
picker.cameraFlashMode = UIImagePickerControllerCameraFlashModeOn;
}
picker.allowsImageEditing = NO;
[self presentModalViewController:picker animated:YES];
[picker release];
}
}
#pragma mark -
#pragma mark UIImagePickerControllerDelegate
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDirectory = [paths objectAtIndex:0];
NSString *imgPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"image1.png"]];
//COnvert it to NSData before saving and then save it
NSData *imgData = UIImagePNGRepresentation(image);
[imgData writeToFile:imgPath atomically:YES];
[self dismissModalViewControllerAnimated:YES];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[self dismissModalViewControllerAnimated:YES];
}

Answer 2

you need to implement UIImagePickerControllerDelegate
Check this function
(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{}
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if ([mediaType isEqualToString:#"public.image"]){
UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage];
}
Now use this UIImage
To save this Image You have to specify a path
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"photo.png"]];
//COnvert it to NSData before saving and then save it
NSData *webData = UIImagePNGRepresentation(editedImage);
[webData writeToFile:imagePath atomically:YES];
