Get width of a resized image after UIViewContentModeScaleAspectFit

Question

I have my UIImageView and I put an image into it that I resize like this:

UIImageView *attachmentImageNew = [[UIImageView alloc] initWithFrame:CGRectMake(5.5, 6.         


        

Answer 1

I don't know is there more clear solution, but this works:

float widthRatio = imageView.bounds.size.width / imageView.image.size.width;
float heightRatio = imageView.bounds.size.height / imageView.image.size.height;
float scale = MIN(widthRatio, heightRatio);
float imageWidth = scale * imageView.image.size.width;
float imageHeight = scale * imageView.image.size.height;
