Question

I have a question about a certain type of method syntax.

For example I know what this does ..

NSString *theString = [[NSString alloc]init...blablabla];

The alloc is performed on the class (NSString in this case) and the init is performed on the instance of the class..

If we have

[variable method];

I know how that functions too.. the method is performed on “variable”

if I have

variable = [instance method];

the “method” method is performed on instance and stored in variable..

But where I get lost is at something that looks like this ..

[[CCDirector sharedDirector]something:parameter];

I’m not sure what action is being performed where..

Answer 1

[CCDirector sharedDirector] is getting the singleton instance of the director. Then you are calling the something method with parameter. It would be similar to doing this

CCDirector* director = [CCDirector sharedDirector];
[director something:parameter];
