Fill an UIBezierPath with a UIImage

Question

I got an UIBezierpath with a circle shape:

UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:rect cornerRadius:100];

But then i want to fill the circle with an UIImage (show only a portion of the image which is inside the circle)

Best Regards Kristian

Edit:

Thanks to Daniel and Dave for excellent answers :D saved me a lot of trouble ;D

The solutions:

CGContextRef ctx = UIGraphicsGetCurrentContext();
CGContextAddPath(ctx, path.CGPath);
CGContextClip(ctx);

and:

path.addClip;

Both works perfectly but i ended up using the last method (by Dave) because it required less code.

you probably want a masked image which should be done without bezier path? — Eimantas, Mar 09 '11 at 17:39

Update: as Dave DeLong points out, there's no need to use Core Graphics functions. This should do the trick:

[path addClip];
[image drawAtPoint:CGPointZero];

+1, though you don't need to drop to CoreGraphics to do this. You can use `-[UIImage draw....]` and `-[UIBezierPath addClip]` to do this. – Dave DeLong Mar 09 '11 at 18:15
Good call Dave -- I hadn't noticed the `addClip` method. Updated the answer showing the UIKit implementation. – Daniel Dickison Mar 09 '11 at 21:14
