How to pass and store information through methods

In the following example when the screen in touched a method is called that passes a number to the view controller that is stored by MyViewController. Only problem the view controller doesn开发者_运维问答't store the number since I want to use it later in another method. Please help. Thank you.

MyViewController.h

@class MyView;

@interface ViewController : UIViewController {
     int number;
}

-(void)assignNumber(int)sentNumber;

@property int number;

MyViewController.m

-(void)loadView {
    MyView *aView = [[MyView alloc] initWithFrame:wholescreen];
    self.view = aView;
    [aView release]; 
}

-(id)initWithNibName...... {
    number = 0;
}

-(void)assignNumber:(int)sentNumber {
    number = sentNumber;
}

MyView.h & MyView.m

Default with TouchesBegin, when touched [viewController assignNumber:5];

If you don't declare @synthesize, you won't be able to access number from outside of the viewController internals. Try adding

@synthesize number;

to the top of MyView.m; This creates setters and getters. then, you can replace your

[viewController assignNumber:5];

call with

[viewController setNumber:5];

and access it with either viewController.number or [viewController number].

You may want to @synthesize the variable number in your ViewController implementation.
