How to scale a UIImageView proportionally?

Question

I have a UIImageView and the objective is to scale it down proportionally by giving it either a height or width.

UIImage *image = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://farm4.static.flickr.com/3092/2915896504_a88b69c9de.jpg"]]]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image];   //Add image view [self.view addSubview:imageView];     //set contentMode to scale aspect to fit imageView.contentMode = UIViewContentModeScaleAspectFit;  //change width of frame CGRect frame = imageView.frame; frame.size.width = 100; imageView.frame = frame; 

The image did get resized but the position is not at the top left. What is the best approach to scaling image/imageView and how do I correct the position?

Answer 1

Fixed easily, once I found the documentation!

 imageView.contentMode = .scaleAspectFit
