簡單整合原生的Camera拍照功能(swift)

要先在class宣告中加入下列兩個Delegate

UIImagePickerControllerDelegate, UINavigationControllerDelegate

在你要用來trigger的function中寫

if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera) {

            var cameraCaptureController = UIImagePickerController()

            cameraCaptureController.delegate = self

            cameraCaptureController.allowsEditing = true

            cameraCaptureController.sourceType = UIImagePickerControllerSourceType.Camera

            self.yourParentViewController?.presentViewController(cameraCaptureController, animated: true, completion: nil)

        }

最後再實作你的Delegate

//MARK: UIImagePickerControllerDelegate, UINavigationControllerDelegate

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {

        dismissCameraCaptureController(picker)

        //TODO: Pick camera capture here

        if let chosenImage = info[UIImagePickerControllerEditedImage] as? UIImage {

            //TODO: use chosenImage here

        } else {

            //TODO: Alert no picture selected.

        }

    }

    

    func imagePickerControllerDidCancel(picker: UIImagePickerController) {

        dismissCameraCaptureController(picker)

    }

    

    private func dismissCameraCaptureController(picker: UIImagePickerController) {

        picker.dismissViewControllerAnimated(true) { }

    }
