Ever wanted a custom crop area for the UIImagePickerController? Now you can have it with GKImagePicker. Just set your custom crop area and that's it. If you don't set it, it uses the same crop area as the default UIImagePickerController.
- just drag and drop the files in under "GKClasses" & "GKImages" into your project.
- look at the sample code below.
- this project contains a sample project as well, just have a look at the implementation of
ViewController.m - have fun and follow @gekitz.
First create and setup the GKImage picker:
let picker = GKImagePicker.init()
picker.delegate = self // required for the optioal delegate, if you want to re-use the cropped image.
picker.cropSize = CGSize.init(width: 200, height: 200) // specify your (starting) crop area
picker.hasResizeableCropArea = true // specify if the crop area can be resized:Then you can present the picker, in a popover for instance:
picker.imagePickerController = UIImagePickerController.init()
picker.imagePickerController!.modalPresentationStyle = .popover // or another presentation style
self.present(self.picker.imagePickerController!, animated: true, completion: nil)
if let popoverPresentationController = self.imagePicker.imagePickerController!.popoverPresentationController {
popoverPresentationController.permittedArrowDirections = .up
popoverPresentationController.barButtonItem = self.customBarButtonItemYou get the possibility to select an image from the photo library.
You need to implement this delegate, if you want to use the cropped image:
extension YourViewController: GKImagePickerDelegate {
func imagePicker(_ imagePicker: GKImagePicker, cropped image: UIImage) {
self.image = image // save the cropped image
self.imagePicker.imagePickerController!.dismiss(animated: true, completion: nil) // dismiss the controller
}
}This library is based on GKImagePicker
