Transfer data from Viewcontroller to UIview

I'm trying to draw a graph in a UIView with 

-(void)drawRect:(CGRect)rect
{
    [super drawRect:rect];
    CGContextMoveToPoint(context, 0f, 0f);
    CGContextAddLineToPoint(context, Value1, 0);
    CGContextStrokePath(context);
}

If I define Value1 Inside my UIView.m it works but: Value1 should be transferred from another ViewController, where i type the Value into a Textfield.

How do I transfer Value 1 into my UIView?

(I could transfer the Value to another ViewController, but in the ViewController my drawRect method doesn't work)

YourViewClass.h

{
@public
    CGFloat Value1;
}

ViewController

myView->Value1 = someValue;
[myView setNeedsDisplay];
