Image Cropping API for iOS

Question

Is there any cropping image API for objective C that crops images dynamically in Xcode project? Please provide some tricks or techniques how could I crop camera images in iP

Answer 1

EDIT - Swift Version

let imageView = UIImageView(image: image)
imageView.contentMode = .scaleAspectFill
imageView.clipsToBounds = true

All these solutions seem quite complicated and many of them actually degrade the quality the image. You can do much simpler using UIImageView's out of the box methods.

Objective-C

self.imageView.contentMode = UIViewContentModeScaleAspectFill;
[self.imageView setClipsToBounds:YES];
[self.imageView setImage:img];

This will crop your image based on the dimensions you've set for your UIImageView (I've called mine imageView here).
It's that simple and works much better than the other solutions.
