I don't think you need two tap gesture recognizers if you are assigning the final image to both UIImageViews. Although, I'm not sure if that solves your problem.

- (void)viewDidLoad
     {

      [super viewDidLoad];

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageTapped:)];
    tap.cancelsTouchesInView = YES;
    tap.numberOfTapsRequired = 1;
    tap.delegate = self;

    [ _imageview addGestureRecognizer:tap];
    _imageview.userInteractionEnabled=YES;

    [_imageview2 addGestureRecognizer:tap];
    _imageview2.userInteractionEnabled=YES;

}
- (void) imageTapped:(UIGestureRecognizer *)gestureRecognizer {
    UIActionSheet*sheet=[[UIActionSheet alloc]initWithTitle:@"Where did you save those pictures!!" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Library",@"camera", nil];
    [sheet showInView:self.view];

}

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
            UIImagePickerController *imagepicker1=[[UIImagePickerController alloc]init];
            imagepicker1.delegate=self;
            imagepicker1.allowsEditing=NO;


      // since you are only changing the source type you need not create two instances 

        if(buttonIndex==0)
        {
            imagepicker1.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
        }
        else if (buttonIndex==1)
        {
            imagepicker1.sourceType=UIImagePickerControllerSourceTypeCamera;
        }
            [self presentViewController:imagepicker1 animated:YES completion:NULL];

}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
   UIImage*orginalImage=[info objectForKey:@"UIImagePickerControllerOriginalImage"];
    _imageview.image=orginalImage;

    // you can assign the same original image to the other image view you need not create another one
    _imageview2.image=originalImage;
    [self dismissViewControllerAnimated:YES completion:NULL];
}


-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{

    [self dismissViewControllerAnimated:YES completion:NULL];
}
