Problem

I am new to iPhone development. I am working with image picker controller in which I want to move and scale the image that picked from the photo library, so I enabled the `allowsediting = yes`. And my picker did finish method: ``` - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Access the uncropped image from info dictionary UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; self.imgForDisplay.image=[self scaleAndRotateImage:image]; self.imagePicker.allowsEditing = YES; ImageDetailsViewController *imageDetailsVC = [[ImageDetailsViewController alloc] init]; imageDetailsVC.imagedisplay.image = self.imgForDisplay.image; [picker pushViewController:imageDetailsVC animated:YES]; //[picker dismissModalViewControllerAnimated:YES]; } ``` and I push another view controller where I want to show the Image picked. Here I have two problems: 1) When I select the image, its navigating to another view without "move and scaling" screen but the image is now displayed in the ImageDetailsViewController when it navigates. 2) When I again navigate back and pick another image, now it shows the "move and scaling" screen. When I click the choose button, it is simply showing a white screen with out navigation bar. Is there any way to set the action for the choose button?
