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

in your case:

float yourScaledImageWitdh =  attachmentImageNew.frame.size.height *  attachmentImageNew.image.size.width / attachmentImageNew.image.size.height
NSLog(@"width of resized pic is %f", yourScaledImageWitdh);

but you should also check, before, the original image proportion vs the imageView proportion, my line of code is good just in case the red area is added horizontally, not in case your original image proportion is wider than the imageView frame proportion
