Prevent Stretching image from uiimage in iphone sdk

enter image description here

Code snippet

        self.newsImage = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,300,130)];
        //set placeholder image or cell won't update when image is loaded
        self.newsImage.image = [UIImage imageNamed:@"newsDetail.png"];
        //load the image
        self.newsImage.imageURL = [NSURL URLWithString:imageBig];
        [imageBack addSubview:self.newsImage];

I have one image on 40*40 size but image view size 300*130. How to avoid stretching image.

I want center of the UIImageview.

Thanks in Advance !!!!

ou have to set CGSize as your image width and hight so image will not stretch and it arrange at the middle.

- (UIImage )imageWithImage:(UIImage )image scaledToFillSize:(CGSize)size
{
    CGFloat scale = MAX(size.width/image.size.width, size.height/image.size.height);
    CGFloat width = image.size.width * scale;
    CGFloat height = image.size.height * scale;
    CGRect imageRect = CGRectMake((size.width - width)/2.0f,
                                  (size.height - height)/2.0f,
                                  width,
                                  height);

    UIGraphicsBeginImageContextWithOptions(size, NO, 0);
    [image drawInRect:imageRect];
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return newImage;
}

Just center the content:

self.newsImage.contentMode = UIViewContentModeCenter;
