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

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];
                }

}
