如何知道UIImageView中的图像大小

Question

I have imageView with some frame

imageView.frame = CGRectMake(0,0, 100, 100);
imageView.contentMode = UIViewContentModeScaleAspectFit;

imageView.image = myImage;

The question is :

Is there any property or method in imageview to know the result size of the image after it's resizing (something like this : imageView.image.size)

(or should i calculate it myself using image size before and imageview frame)?

无法查询缩放图像的大小，您必须使用图像大小和大小限制自行计算。
