copied!<p>For reusable code, you only want one version of <code>PopViewController</code>. Your two versions look identical, so get rid of one. In InterfaceBuilder, set your buttons to all segue to a single PopViewController. Root View Controller, then, looks like this:</p> <pre><code>@property (strong, nonatomic) IBOutlet UIButton *btnOpenPopover1; @property (strong, nonatomic) IBOutlet UIButton *btnOpenPopover2; </code></pre> <p>In <code>prepareForSegue:</code>, rather than segue to one version or another of <code>PopViewController</code>, just segue to your single version. Add a property to Root View Controller, to keep track of it (this replaces pvc1 and pvc2):</p> <pre><code>@property (strong, nonatomic) PopViewController* currentPopoverController; </code></pre> <p>You also need to keep track of which button is being edited, so add a property to your Root View Controller for that (note the weak reference):</p> <pre><code>@property (weak, nonatomic) IBOutlet UIButton* currentButton; </code></pre> <p>Set both of these in <code>prepareForSegue:</code>, so it looks like this:</p> <pre><code>-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { currentPopoverController = [segue destinationViewController]; [currentPopoverController setDelegate:self]; currentButton = (UIButton*) sender; } </code></pre> <p>Now, you only need one delegate that looks like this:</p> <pre><code>- (void)dismissPop:(NSString *)value { [currentButton setTitle:value forState:UIControlStateNormal]; [currentPopoverController dismissPopoverAnimated:YES]; } </code></pre>
