UIImage *image = (UIImage *) [info valueForKey:UIImagePickerControllerOriginalImage];
NSLog(@"%f %f %f %f ", (image.size.width/9), (image.size.height/16), (568/image.size.height), (round((568/image.size.height) * image.size.width)));
if((image.size.width/9)<(image.size.height/16)){
    imageLoad.frame = CGRectMake(0, 0, 320, round((320/image.size.height) * image.size.height));
}
else if((image.size.width/9)>(image.size.height/16)){
    imageLoad.frame = CGRectMake(0, 0, round((568/image.size.height) * image.size.width), 568);
}
else{
    imageLoad.frame = CGRectMake(0, 0, round((568/image.size.height) * image.size.width), 568);
}
NSLog(@"%f %f", imageLoad.frame.size.width, imageLoad.frame.size.height);
imageLoad.hidden = NO;
imageLoad.image = image;

我改变了UIImageView *imageLoadusing的大小CGRectMake，我以为UIImage *image会显示为UIImageView *imageLoad. 但是，它没有用。我应该怎么办？
