Body
I have a class defined in a an external pair of files, let's name them engine.h and engine.m . Also, it was given to me the file "engineListener.h". this is how they look: File engine.h: <pre><code>@interface coreEngine: NSObject { NSString *displaydValue; id <coreEngineListener> listener; } -(coreEngine*)initWithListener:(id <coreEngineListener>) _listener; //... </code></pre> File engine.m <pre><code>//imports here @interface coreEngine() -(Boolean) MyOperation: ... ... (etc) @end </code></pre> File engineListener.h <pre><code>//imports here... @class coreEngine; @protocol coreEngineListener <NSObject> @required -(void) someVariable:(coreEngine *)source; @end </code></pre> <hr> Now, in my myController.h I have this: <pre><code>//... imports and include ... @interface myController : NSObject { coreEngine *PhysicsEngine; } - (IBAction)doSomething:(id)sender; </code></pre> And in the myController.m this is what I have: <pre><code>-(id) init { NSAutorelease *pool = [[NSAutoreleasePool alloc] init]; coreEngine *PhysicsEngine = [[coreEngine alloc] init]; [PhysicsEngine release]; [pool drain]; return self; } - (IBAction)doSomething:(id)sender { [PhysicsEngine MyOperation:Something]; } </code></pre> The thing now is: the code compiles correctly, but the "[PhysicsEngine MyOperation:Something]" is doing nothing. I'm sure I'm instantiating my class wrongly. The NSObject defined in "engine.h engine.m and enginelistener.h" that I have to load was not made by me, and I have no means to modify it. I've tried doing some dummy/random things based on what I've seen around on the internet, without knowing 100% what I was doing. I'm not even close to be familiar with ObjectiveC or C/C++, so be gentle with me. I'm totally noob on this subject. I'm using Xcode 4, and I have also access to XCode 3.2.6 How should I load my class properly? Any advice is welcome. Thanks

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
