Create a CGImage from the data then a UIImage from that

        CFDataRef cfdata = CFDataCreate(NULL, frameBuf, size);
        CGDataProviderRef dataProv = CGDataProviderCreateWithCFData(cfdata);
        CGImageRef cfimg = CGImageCreate(w, 
                                         w * bytesPP, 
                                         rgbColour, bmpInfo, dataProv, 

        [self setImage: [UIImage imageWithCGImage:cfimg]];

Something like that.
