Question

I know i have done this before, but I just cant remember how to do it.

I have a integer, that i want to be able to change in another class of mine.

how do i do it?

MainViewClass : UIViewController {
int score;
}


#import "MainViewClass.h"
OtherClass : MainViewClass{

}

Then in the .m of OtherClass i want to be able to use the variable score.

How do i do this?

I have searched around the internet, and have tried several things to try to get it to work will no success.

Thanks for looking!
Have a wonderful day.

In your MainViewClass.h, you’ll want to add your int as a property of that class.

@property (nonatomic, readwrite) int score;

Then in your MainViewClass.m, you’ll want to synthesize the property using:

@synthesize score;

Now since your subclassing MainViewClass in your OtherClass you can access it’s properties using some combination of the following.

In your OtherClass.h add

MainViewClass *mainViewClass;

in your OtherClass.m wherever you need access to the score, you should be able to access it as such.

mainViewClass = (MainViewClass *) self.parent;

and then the score using,

mainViewClass.score;
