copied!<p>It is not working because you are sending removeFromSuperview to the wrong view object. This is what you need:</p> <pre><code>[medicalViewObject.view removeFromSuperview]; </code></pre> <p>EDIT:</p> <p>Your question suggests that you have a view (because you did not include the name of this view in your question, I will simply call it MainView) and then you add a subview called medicalViewObject to your MainView. You also have a method call "BackToMainView" which you want to perform the removeFromSuperview function. Your question suggests that some user action in your medicalViewObject (such as a button press) is supposed to call the "BackToMainView" method.</p> <p>If this is all correct, then my answer above is correct. But based upon your comment, it sounds like you will also need to implement a delegate protocol in your medicalViewObject, and then have your "MainView" adopt the protocol.</p> <p>In your declaration of the delegate in your medicalViewObject, you need to have a method call like this:</p> <pre><code>-(void)backButtonWasPressed; </code></pre> <p>and in the implementation of your MainView it should look something like this:</p> <pre><code>-(void)backButtonWasPressed { [medicalViewObject.view removeFromSuperview]; } </code></pre> <p>So now, whatever user action you are using in your medicalViewObject to go back to the main view (whether a button or some other object) it needs to call the following:</p> <pre><code>[delegate backButtonWasPressed]; </code></pre> <p>Depending on your situation it may look a little different, but this a fairly common way to accomplish what you are trying to do. I hope this helps.</p>
