UIColor *brushPattern=[[UIColor alloc]initWithPatternImage:[UIImage imageNamed:@"[email protected]"]];
CGContextSetStrokeColorWithColor(UIGraphicsGetCurrentContext(),brushPattern.CGColor);

I have used the following code for the same

At ViewDidLoad or Where ever your going to start the assign this 

 patternColor = [UIColor colorWithPatternImage:image]

This will resolve your memory issues and below code willhelp you

UIGraphicsBeginImageContextWithOptions(view.frame.size, NO, [[UIScreen mainScreen] scale]);

CGContextRef context = UIGraphicsGetCurrentContext();
[view.image drawInRect:CGRectMake(0, 0, view.frame.size.width, view.frame.size.height)];

CGContextSetInterpolationQuality(context, kCGInterpolationHigh);
CGContextSetLineCap(context, kCGLineCapRound);
CGContextSetLineWidth(context, 10);

CGContextSetStrokeColorWithColor(UIGraphicsGetCurrentContext(), patternColor.CGColor);
CGContextSetBlendMode(context, kCGBlendModeNormal);

CGContextBeginPath(context);
CGContextMoveToPoint(context, lastPoint.x, lastPoint.y);
CGContextAddLineToPoint(context, currentPoint.x, currentPoint.y);
CGContextStrokePath(context);
UIImage * img = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
