Question

Let’s say I have a view controller called vc1, which a synthesized property called property1, and i wants to access it from another view controller (vc2) and change it from vc2.

Now the methods created by the @syntisize to change and get properties are instance methods, so how can I get to them fro another view controller (do view controllers have instances in the app, and if so, what are they?)

Just to be clear I am using storyboards, so I never really instantiate the view controllers…

Answer 1

VC1.m:

-(void) yourMethod {
     ...
}

VC2.m

YOURViewController * vc2 = [[YOURViewController alloc]init];
[vc yourMethod];
[vc release];

Make sure to import your YOURViewController in your other view .m file
Something like that should work.

Or if you’re having problems, try this tutorial here:
