draw a stroke around the shape, core graphic - objective-c

Question

I am drawing a shape like following :
- (void)drawRect:(CGRect)rect
{
// Draw a cross rectagle
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSaveGState(context);
CGContextMoveToPoint(context, 190, 0);
CGContextAddLineToPoint(context, 220, 0);
CGContextAddLineToPoint(context, 310, 90);
CGContextAddLineToPoint(context, 310, 120);
CGContextSetFillColorWithColor(context, [UIColor lightGrayColor].CGColor);
CGContextFillPath(context);
CGContextRestoreGState(context);
}
I am getting a light-dark cross flag below
Now I would like to draw a stroke around the cross flag I have just drawn
What should I do to achieve this. Please advice me on this issue.
Thanks.

Answer 1

Surely CGContextDrawPath(context, kCGPathFillStroke); is what you're after
You can adjust the pattern and color using:
CGContextSetStrokePattern
CGContextSetStrokeColor
https://developer.apple.com/library/ios/#documentation/graphicsimaging/reference/CGContext/Reference/reference.html
So, in your case, assuming you want a plain black stroke, you'd have:
- (void)drawRect:(CGRect)rect
{
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSaveGState(context);
CGContextSetLineWidth(context, 2.0);
CGContextSetStrokeColorWithColor(context, [UIColor blackColor].CGColor);
CGContextSetFillColorWithColor(context, [UIColor lightGrayColor].CGColor);
CGContextMoveToPoint(context, 190, 0);
CGContextAddLineToPoint(context, 220, 0);
CGContextAddLineToPoint(context, 310, 90);
CGContextAddLineToPoint(context, 310, 120);
CGContextClosePath(context);
CGContextDrawPath(context, kCGPathFillStroke);
CGContextFillPath(context);
CGContextRestoreGState(context);
}

- (void)drawRect:(CGRect)rect
{
// Draw a cross rectagle
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSaveGState(context);
//New
CGContextSetLineWidth(context, 2.0);
CGContextMoveToPoint(context, 190, 0);
CGContextAddLineToPoint(context, 220, 0);
CGContextAddLineToPoint(context, 310, 90);
CGContextAddLineToPoint(context, 310, 120);
//New
CGContextSetStrokeColorWithColor(context, [UIColor blackColor].CGColor);
CGContextSetFillColorWithColor(context, [UIColor lightGrayColor].CGColor);
CGContextFillPath(context);
//New
CGContextStrokePath(context);
CGContextRestoreGState(context);
}
#WDUK :after spending hours to figure it out, I know why your above answer is not working.
The reason is when you do CGContextFillPath first, the path is eventually cleared and then you can no long do CGContextStrokePath on it again.
Therefore in order to do CGContextFillPath and CGContextStrokePath, we have to do
CGContextDrawPath(context, kCGPathFillStroke);
After trying it , I am getting the following
