I have a custom class which I want to "load" inside the firstViewController and then access it from other classes by segues. My Problem is, I can't even access and change the instance variable inside the firstViewController. Somehow I'm "loading" it wrong. Here is the code I used until now:

inside viewController.h

@property (strong, nonatomic) myClass *newClass;

inside viewController.m

@synthesize newClass;

I then try to access it by:

self.newClass.string = @"myString";
if(newClass.string == @"myString"){
  NSLog(@"didn't work");
}

Well, I get "didn't work". Why is that? When I write

myClass *newClass = [myClass new];

It does work. But the class and its properties gets overwritten every time the ViewController loads again.

What would you recommend? Thank you very much.
