Question

I set an UIImage in a UIImageView, with contentMode AspectToFit. How can I acces the frame of the resized displayed UIImage ? because imageView.image.size.width gives the original width of the image, not the resized width.

Thanks,

Property frame of UIImageView will return the frame of the displayed image.

If you want change frame you should just set new CGRect frame to your UIImageView

For example:

UIImageView *imgView;
imgView.frame = CGRectMake(0, 0, newWidth, newHeight);

Updated:

To calculate new size you can use following code:

UIImage *img;
UIImageView *iView;    
double widthRatio = img.size.width/iView.frame.size.width;
double heightRatio = img.size.height/iView.frame.size.height;
double ratio = widthRatio>heightRatio?widthRatio:heightRatio;
CGSize newImageSize;
newImageSize.width = img.size.width/ratio;
newImageSize.height = img.size.height/ratio;
