(iphone) am I creating a leak when creating a new image from an image?
- by Eugene
Hi,
I have following code as UIImage+Scale.h category.
-(UIImage*)scaleToSize:(CGSize)size
{
UIGraphicsBeginImageContext(size);
[self drawInRect:CGRectMake(0, 0, size.width, size.height)];
// is this scaledImage auto-released?
UIImage* scaledImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return scaledImage;
}
I use image obtained as above and use it as following.
UIImage* image = [[UIImage alloc] initWithData: myData];
image = [image scaleToSize: size]; <- wouldn't this code create a leak since
image(before scaling) is lost somewhere?
i guess above codes work fine if image was first created with auto-release.
But if image was created using 'alloc', it would create a leak in my short knowledge.
How should I change scaleToSize: to guard against it?
Thank you
