How to pass Value from UIViewController to UIView?

i have creted a UIView Subclass:

@interface GraphClass : UIView
{
    NSString *str;
}

And i have assigned GraphClass: to a View of an UIViewController Class named:

@interface GraphViewController : UIViewController
{


}

Now i want to pass NSString *amount,value from another UIViewController Class

@interface MonthsListController : UIViewController
{
}
in viewDIdLoad

- (void)viewDidLoad
{
GraphClass *graph = [[GraphClass alloc]init];

graph.str = @"abc";

But am getting NULL value if i print str Value in GraphClass

-(void)drawRect:(CGRect)rect
{
    NSLog(@"Amount is = %@",str);//NULL VAlue :(
}
}

#import "GraphClass.h"

// in UIViewController Class 

GraphClass *graph = [[GraphClass alloc] init];

graph.recStr=Amount;

[self.view addSubview:graph];

// In GraphClass

@interface GraphClass : UIView
{
    NSString *recStr;
}

@propery (nonatomic,strong)  NSString *recStr;
