Question

I have a class, in that class I have set up a singleton patter and have a method, here is a short example of what it looks like.

#pragma mark Singleton Methods
+ (id)sharedManager {
    @synchronized(self) {
        if (sharedMyManager == nil)
            sharedMyManager = [[self alloc] init];
    }
    return sharedMyManager;
}
- (id)init {
    if (self = [super init]) {
//so some init stuff here
//...
}

-(void)savemethod {
//etc etc
}

I’m wondering if I am to call/initalize the singleton class to be used like so

//set up plist controller class as a singleton so that you dont loose cache numbers etc
    EnginePropertiesController *enginePC = [EnginePropertiesController sharedManager];

then later on in the same class where I have initialized the singleton I call the save method…

[enginePC saveMethod];

So what im wondering is saveMethod part of the same instance? I think it is because i am using the same initialization name enginePC.. but would like some clarification on this.

If I’m understanding you, you are correct that saveMethod would be called on the singleton instance. What you name a pointer has no bearing on what it points to.
