how to convert UIView code into UIViewController with Nib in ipad - iphone

Question

I have found tutorial which I want to implement in my view controller but the code is written in UIView so how to convert UIView code into UIViewController it can work here is my code
#import <UIKit/UIKit.h>
#interface MyLineDrawingView : UIView {
UIBezierPath *myPath;
UIColor *brushPattern;
}
#end
#import "MyLineDrawingView.h"
#implementation MyLineDrawingView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
self.backgroundColor=[UIColor whiteColor];
myPath=[[UIBezierPath alloc]init];
myPath.lineCapStyle=kCGLineCapRound;
myPath.miterLimit=0;
myPath.lineWidth=10;
brushPattern=[UIColor redColor];
}
return self;
}
Only override drawRect: if you perform custom drawing.
An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
[brushPattern setStroke];
[myPath strokeWithBlendMode:kCGBlendModeNormal alpha:1.0];
// Drawing code
//[myPath stroke];
}
#pragma mark - Touch Methods
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *mytouch=[[touches allObjects] objectAtIndex:0];
[myPath moveToPoint:[mytouch locationInView:self]];
}
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *mytouch=[[touches allObjects] objectAtIndex:0];
[myPath addLineToPoint:[mytouch locationInView:self]];
[self setNeedsDisplay];
}
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
//handle touch event
}

Create a UIViewController Object and set the view property to this view. Something like this should work.
UIViewController *vc = [[UIViewController alloc] init];
MyLineDrawingView *myView = [[MyLineDrawingView alloc] init];
vc.view = myView;
