resize UIImage in table cell programmatically - ios4

Question

how can i resize the UIImage in table cell
cell.imageView.layer.masksToBounds = YES;
cell.imageView.layer.cornerRadius = 5.0;
cell.imageView.frame=CGRectMake(0, 0, 20, 30);
cell.imageView.image =[UIImage imageNamed:#"Diseases.png"];
it is not working

Answer 1

Use this method, pass the size and image, and get the image then show in cell
+ (UIImage *)imageWithImage:(UIImage *)image scaledToSize:(CGSize)newSize {
UIGraphicsBeginImageContext(newSize);
[image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
You can also make your custom UITableViewCell, and design as you want to look it

Answer 2

This worked for me.
///////////////////////////////// TO RESIZE IMAGE //////////////////////////////////
////////// FIRST WRITE DESIRED SIZE AND CALL BELOW FINCTION ///////
CGSize newSize ;
newSize.width = 30;
newSize.height = 30;
UIImage *imgSelectedNew = [self imageWithImage:savedImage scaledToSize:newSize];
- (UIImage*)imageWithImage:(UIImage*)sourceImage scaledToSize:(CGSize)targetSize
{
//UIImage *sourceImage = sourceImage;//= self;
UIImage *newImage = nil;
CGSize imageSize = sourceImage.size;
CGFloat width = imageSize.width;
CGFloat height = imageSize.height;
CGFloat targetWidth = targetSize.width;
CGFloat targetHeight = targetSize.height;
CGFloat scaleFactor = 0.0;
CGFloat scaledWidth = targetWidth;
CGFloat scaledHeight = targetHeight;
CGPoint thumbnailPoint = CGPointMake(0.0,0.0);
if (CGSizeEqualToSize(imageSize, targetSize) == NO) {
CGFloat widthFactor = targetWidth / width;
CGFloat heightFactor = targetHeight / height;
if (widthFactor < heightFactor)
scaleFactor = widthFactor;
else
scaleFactor = heightFactor;
scaledWidth = width * scaleFactor;
scaledHeight = height * scaleFactor;
// center the image
if (widthFactor < heightFactor) {
thumbnailPoint.y = (targetHeight - scaledHeight) * 0.5;
} else if (widthFactor > heightFactor) {
thumbnailPoint.x = (targetWidth - scaledWidth) * 0.5;
}
}
// this is actually the interesting part:
UIGraphicsBeginImageContext(targetSize);
CGRect thumbnailRect = CGRectZero;
thumbnailRect.origin = thumbnailPoint;
thumbnailRect.size.width = scaledWidth;
thumbnailRect.size.height = scaledHeight;
[sourceImage drawInRect:thumbnailRect];
newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
if(newImage == nil)
NSLog(#"could not scale image");
return newImage ;
}
well m also n indorian , Gud to see the other one !!! :)
