    You have to implement it your self.

    The picker only performs 320x320 cropping.

    So instead set

    allowsImageEditing = NO;

    Now you will get the full image back. Then you will have to create a view/view controller that will crop to the proportions you desire.

    You can try ShittyImageCrop. It's good for cropping to a specific aspect ratio. In your case, present it with aspect ratio 4:3 (or 3:4 in landscape) like this:

    let cropVC = ShittyImageCropVC(frame: (self.navigationController?.view.frame)!, image: imageToCrop, aspectWidth: 4, aspectHeight: 3)
    self.navigationController?.present(cropVC, animated: true, completion: nil)
    

    After that you can use some other code to just scale it to desired resolution (320x240 or 240x320).

    This is the more recent answer with the necessary manual cropping code: Manual Crop

    There is still no escaping the hard work.
