iOS : Save image with custom resolution
===

Hi I am try to capture a view then save as an image into Photo Library , but I need create a custom resolution for captured image , here is my code but when app saves the images the resolution is low !

        UIGraphicsBeginImageContextWithOptions(self.captureView.bounds.size, self.captureView.opaque, 0.0);
        
        [self.captureView.layer renderInContext:UIGraphicsGetCurrentContext()];
        UIImage * screenshot = UIGraphicsGetImageFromCurrentImageContext();
    
    CGRect cropRect = CGRectMake(0 ,0 ,1435 ,1435);
        CGImageRef imageRef = CGImageCreateWithImageInRect([screenshot CGImage], cropRect);
        CGImageRelease(imageRef);
        
        UIImageWriteToSavedPhotosAlbum(screenshot , nil, nil, nil);
         
        UIGraphicsEndImageContext();

but the resolution in iPhone is : 320 x 320 and retina is : 640 x 640 

I would be grateful if you help me to fix this issue .
