Mask Image to Round in iOS

I know there are many questions about mask but answers for them didn't help me (just partly).

I need to do my image round. I created mask.png and use it in code:

- (UIImage*) maskImage:(UIImage *)image withMask:(UIImage *)maskImage {    
CGImageRef maskRef = maskImage.CGImage; 

CGImageRef mask = CGImageMaskCreate(CGImageGetWidth(maskRef),
                                    CGImageGetHeight(maskRef),
                                    CGImageGetBitsPerComponent(maskRef),
                                    CGImageGetBitsPerPixel(maskRef),
                                    CGImageGetBytesPerRow(maskRef),
                                    CGImageGetDataProvider(maskRef), NULL, false);

CGImageRef masked = CGImageCreateWithMask([image CGImage], mask);
UIImage* maskedImage = [UIImage imageWithCGImage:masked];

CGImageRelease(masked);
CGImageRelease(mask);
return maskedImage;
}

Everything was great and everybody was happy. But when I start test this method at device I found that it isn't mask my image (in simulator everything working ok). How I can mask my image?

P.S. Temporarily I seted view.layes.mask as layer with my mask. And this variant is working at the device. May be any way to save round from this layer?

Its not required to do all those stuffs if all you needed is a round imageview.

UIImageView * myimageview = [[UIImageView alloc]init];
myimageview.layer.cornerRadius = myimageview.frame.size.height;
myimageview.layer.masksToBounds = true;

use the above code and set any image to that imageview and you will get a round imageview. here you're not making the image round, but the imageview.
