Edit image after taking a picture

Question

I\'m currently making an iphone app where the user takes a photo or select it from an album, then an overlay is placed over the image. The user can then scale, rotate and save t

Answer 1

For Q1, is it possible to implement an action sheet, so that the user can choose to use the photo from an album or take a new pic.? with the action sheet function as something like the following:

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0) {
        picker = [[UIImagePickerController alloc]init];
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        picker.delegate = self;
        [self presentModalViewController:picker animated:YES];
        [picker release];
    }

    else if (buttonIndex == 1) {
        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
            picker = [[UIImagePickerController alloc]init];
            picker.sourceType = UIImagePickerControllerSourceTypeCamera;
            picker.allowsEditing = YES;
            picker.delegate = self;
            [self presentModalViewController:picker animated:YES];
            [picker release];
        }
        else {
            UIAlertView *noCameraMsg = [[UIAlertView alloc] initWithTitle:@"no camera on this phone" message:@"" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
            [noCameraMsg show];
            [noCameraMsg release];

        }
